Wallpaper Peeling Away From the Wall

1st September 2026 Matt Warren

Wallpaper peeling away from the wall is annoying, but it is also useful evidence. If the wall is dry and only one seam has lifted, it may be a simple decorating repair. If the paper feels damp, smells musty or keeps coming loose after you stick it back, the wallpaper is probably showing you a problem behind the surface.

If you searched for wallpaper peeling off wall because it has suddenly started lifting, start with a few quick checks before buying more paste. The right next step depends on whether this is a decorating issue, a damp issue, a leak or a plaster problem.

Quick checks before you try to fix it

Do not pull large sheets off straight away. You may remove useful clues, and if the wall is damp you could make a small repair look much worse.

Start by looking at where the wallpaper is peeling. Paper lifting near a window, external wall, chimney breast, bathroom, kitchen or radiator can point to moisture. Paper lifting across a whole room, especially soon after decorating, often points to poor wall preparation or paste failure.

Use the back of your hand to feel the wall lightly. If it feels cold and slightly damp, or if there is a musty smell, staining, black specks, bubbling paint or soft plaster underneath, treat the wallpaper as a symptom rather than the main problem.

If water is actively dripping or running down the wall, turn off the water at the stop tap if you can do so safely and call a plumber. If the wall is wet near sockets, switches or electrical fittings, do not touch the electrics. Turn off the affected circuit only if it is safe and easy to do, then get professional help.

Common causes of wallpaper peeling and who to call

Most dry peeling wallpaper is handled by a painter and decorator. If the wall is wet, crumbling or stained, another trade may need to fix the root cause before any redecorating will last. You can compare current painter and decorator rates on HaMuch before asking for quotes, which helps you avoid vague national averages and see real local pricing.

Likely cause	What you might notice	Trade usually needed first
Poor surface preparation	Dry seams lifting, paper coming away in sheets, no staining or smell	Painter & Decorator
Old paste or old wallpaper	Edges curling, brittle paper, gaps at seams	Painter & Decorator
Condensation	Peeling near windows, external walls or behind furniture, possible black mould	Ventilation & AC Engineer, then Painter & Decorator
Plumbing leak	Localised damp patch, staining, peeling below a bathroom or near a radiator	Plumber
Penetrating damp	Peeling after rain, damp on an external wall, chimney breast or ceiling edge	Builder or roofing and guttering specialist
Damaged or fresh plaster	Bubbling, hollow patches, powdery plaster or paper not sticking to new walls	Plasterer, then Painter & Decorator
Heat and steam	Peeling in kitchens, bathrooms or behind radiators	Painter & Decorator, sometimes Ventilation & AC Engineer

This table is a guide, not a diagnosis. The important point is sequence. If moisture is causing the paper to lift, a decorator can make it look better for a short time, but the wallpaper will often peel again until the damp, leak or ventilation issue is fixed.

When it is probably a decorating problem

A straightforward decorating issue is likely when the wall feels dry, there are no brown stains, no mould, no soft plaster and the peeling is mainly at seams or corners. This can happen when wallpaper has been hung over dusty plaster, shiny paint, old paste residue or a wall that was not properly sealed before papering.

It can also happen if the wallpaper is old. Paste weakens over time, especially in rooms with changing temperatures. South-facing rooms, radiator walls and homes that have been empty for a while can all have curling edges without there being a leak.

A painter and decorator may repair a small lifted seam with specialist seam adhesive, smooth down blisters, strip and rehang a damaged section or recommend removing and repapering the wall. If several drops of paper are loose, patching may not be the best use of money because the remaining adhesive may already be failing.

For landlords and property managers, it is worth asking the decorator whether the repair is cosmetic or whether they can see signs of a deeper fault. That note can help you decide whether to send another trade before redecorating a rental property.

When peeling wallpaper points to damp, leaks or ventilation

Moisture is one of the most common reasons wallpaper peels away from a wall. Wallpaper paste is water based, so damp can soften it, loosen the bond and leave the paper bubbling or curling.

Condensation is common in bedrooms, bathrooms and kitchens. Warm moist air settles on cold surfaces, especially external walls, window reveals and corners with poor airflow. If the paper is peeling behind a wardrobe, near a window or in a room with regular black mould, the problem may be ventilation rather than a hidden leak. A Ventilation & AC Engineer can advise on extractor fans, airflow and practical improvements, while a decorator can repair the finish once the wall is dry.

In rental homes, damp and mould should be taken seriously. GOV.UK guidance on damp and mould in rented property makes clear that landlords should identify and deal with the underlying cause rather than simply treating mould as a housekeeping issue.

A plumbing leak is more likely when peeling is localised below a bathroom, near a radiator, behind a kitchen unit or on a ceiling line under a water source. If you suspect a leak, compare local plumber rates on HaMuch before booking, or use HaMuch's checklist for finding a reliable plumber if you have not hired one before.

Penetrating damp usually starts from outside. Rainwater can get in through cracked render, damaged brickwork, faulty gutters, failed seals around windows or roofline problems. In that case, a builder or roofing and guttering specialist usually needs to investigate before the inside wall is repaired. You can check current builder rates by location if the wallpaper is peeling on an external wall and the issue gets worse after rain.

If the wallpaper is peeling because the plaster underneath is loose, powdery or blown, a decorator may not be able to guarantee a lasting finish. A plasterer may need to repair or skim the wall first. HaMuch also lists plasterer rates, which is useful if you need to budget for wall preparation before decorating.

How much might it cost to sort?

The cost depends less on the wallpaper itself and more on what is causing it to peel. A dry seam repair is very different from a damp wall that needs a leak fixed, plaster repaired and the room redecorated.

HaMuch is built to make this easier to compare. Instead of giving you one vague figure for the whole country, HaMuch shows real, comparable pricing by trade and UK location. That matters because labour rates can vary between large city areas, surrounding towns and smaller local markets.

Cost factor	Why it changes the quote
Size of the affected area	A small seam repair is quicker than stripping and repapering a full wall
Whether the wall is dry	Damp walls need the cause fixed and drying time before decorating
Condition of the plaster	Crumbly or hollow plaster may need repair before wallpaper will stick
Access	High walls, stairwells and awkward corners take longer
Matching existing wallpaper	Older or discontinued wallpaper may make patch repairs harder
Number of trades needed	A plumber, builder or plasterer may be needed before the decorator

If you are comparing quotes, ask each tradesperson what is included. For example, does the decorator include stripping loose paper, preparing the wall and supplying adhesive, or is the quote only for hanging new paper? If a plumber fixes a leak, will they make good the wall, or will you need a plasterer and decorator afterwards?

Can you fix peeling wallpaper yourself?

If the wall is completely dry and only a small seam has lifted, a DIY repair may be enough. Gently lift the loose edge, remove dusty old adhesive, apply wallpaper seam adhesive, smooth it back down with a clean cloth and wipe away excess adhesive. Keep the room at a steady temperature while it dries.

Do not glue wet wallpaper back onto the wall. It may trap moisture, encourage mould and hide a leak for longer. You should also avoid painting over peeling wallpaper unless you are sure the surface is dry, sound and firmly stuck down. Paint can make peeling edges more obvious and harder to repair neatly.

If the wallpaper is bubbling over a wide area, the plaster feels soft or the same patch keeps peeling after repair, it is time to get a tradesperson involved. A good decorator will tell you if the job is not ready for decorating yet, which can save you paying twice for the same wall.

What to tell a tradesperson when asking for quotes

A clear job description helps you get more accurate quotes. Before posting the job, take photos from the room and from a closer distance, but avoid pulling large areas off the wall. Note whether the wall feels damp, whether the peeling changes after rain, whether there is mould and whether there is a bathroom, kitchen, radiator or external wall nearby.

If you manage a rental property, include when the tenant first reported the problem and whether it is affecting one room or several. If there has been a previous leak or decorating work, mention it. This helps the right trade respond rather than sending a decorator to what is really a plumbing or damp issue.

You do not need to diagnose the fault perfectly. Describe what you can see and feel. A useful description might be: wallpaper peeling on external bedroom wall, cold to touch, slight black mould near window, worse in winter. That points a tradesperson towards ventilation and damp checks rather than a simple paste repair.

Frequently Asked Questions

Why is my wallpaper peeling away from the wall? Wallpaper usually peels because the adhesive has failed, the wall was not prepared properly, the paper is old or moisture is affecting the wall. Moisture can come from condensation, a plumbing leak or rain getting through the outside of the property.

Does peeling wallpaper always mean damp? No. Dry peeling at seams or corners is often a decorating issue. Damp is more likely if the wall feels wet or cold, has brown staining, smells musty, has mould or the peeling keeps coming back after repair.

Who should I call for wallpaper peeling off the wall? For dry peeling, call a painter and decorator. For wet patches near pipework, bathrooms or radiators, call a plumber first. For crumbling plaster, call a plasterer. For rain related damp on an external wall, a builder or roofing and guttering specialist may be needed before decorating.

Can a decorator repair peeling wallpaper in one visit? Sometimes, yes, if it is a small dry seam or corner. If the wall needs stripping, drying, plaster repair or leak repairs, it may take more than one visit and another trade may need to attend first.

Should I remove the wallpaper before getting quotes? Usually, no. Photos of the wallpaper as it is can help tradespeople understand the pattern of the problem. Only remove loose paper if it is already falling away and safe to do so. Do not strip damp wallpaper near electrics.

Is peeling wallpaper a landlord repair issue? It can be. If the peeling is caused by damp, leaks, defective plaster or poor ventilation in the property, the landlord normally needs to investigate and arrange repairs. If it is simple wear and tear or minor cosmetic damage, the response may depend on the tenancy and the cause.

Get the right trade to look at it

If your wallpaper is peeling and you are not sure whether to call a decorator, plumber, plasterer or builder, post the job on HaMuch. Describe where the wallpaper is lifting, whether the wall feels damp and whether the problem changes after rain, heating or shower use.

HaMuch lets you request quotes from local tradespeople, compare genuine reviews and check transparent pricing before you decide. It is free for homeowners to use, and there is no obligation to book until you are happy with who you have found.

Electric Shower Suddenly Running Cold

30th August 2026 Matt Warren

If your electric shower suddenly runs cold, it is usually one of three things: the shower is not getting the right water flow, the unit is not heating properly or there is an electrical fault stopping

The good news is that you can do a few simple checks without touching anything dangerous. The key is knowing where to stop. Electric showers mix water and high-powered electrics, so you should never remove the cover, poke inside the unit or keep resetting a tripping fuse box to “see if it works this time”.

This guide explains why an electric shower keeps going cold, what you can safely check now and whether you need an electrician, a plumber or both.

First, stop using the shower if there are warning signs

A cold shower is annoying, but some symptoms mean you should turn it off and get help quickly. Stop using the shower if you notice a burning smell, buzzing, crackling, flickering lights, scorch marks, water leaking from the shower casing or a consumer unit that trips when the shower is switched on.

If the shower has tripped the electrics, do not keep resetting the switch. Repeated tripping can point to a faulty shower unit, damaged wiring, water getting where it should not or an overloaded circuit. HaMuch has a separate guide on what to do when a fuse box keeps tripping for no obvious reason, but for an electric shower fault you should treat it as a job for a qualified electrician.

If there is water leaking from the shower unit itself, switch it off at the pull cord or isolator only if it is safe and dry to do so. Keep clear of the shower and call a tradesperson.

Why an electric shower can suddenly run cold

An electric shower works differently from a mixer shower. It does not usually use hot water from your boiler or cylinder. Instead, it takes cold mains water and heats it instantly inside the shower unit.

That means a cold electric shower is not normally caused by your boiler. Your hot kitchen tap may be fine, but the shower can still run cold because the problem is inside the shower unit, the electrical supply or the incoming cold water flow.

A useful way to think about it is this: the shower has to balance water flow and heat. If the water moves through too quickly, it may not heat enough. If the flow drops too low, the unit may cut the heat for safety. If an internal part fails, the shower may run completely cold even though water still comes out.

Safe checks you can do before calling someone

Before you book a tradesperson, check the simple things from outside the shower unit. These checks may help you describe the fault clearly, and in some cases they may solve a minor issue.

Check the temperature dial has not been moved to cold or eco mode.
Turn the flow down slightly and see whether the water warms up.
Remove and descale the showerhead if the spray is weak or uneven.
Check whether the problem happens when another tap, washing machine or toilet is being used.
Look at the consumer unit to see whether the shower circuit or RCD has tripped.
Check whether the pull cord or isolator switch is fully on, but do not touch it if it is wet, damaged or discoloured.

Do not remove the shower cover. Even when the shower is switched off at the front panel, parts of the circuit may still be dangerous unless properly isolated and tested.

If turning the flow down makes the shower warm again, the unit may be struggling to heat the amount of water passing through it. If there is no heat at all, or if the shower heats for a short time then goes cold again, it is more likely to need a professional check.

Common causes and who to call

The same symptom can point to different faults, so the right trade depends on what else is happening. In many cases, an electrician is the first person to call because the heating parts and power supply are inside the electric shower unit. A plumber may be needed where the issue is water pressure, pipework, valves or a leak.

What you notice	Likely cause	Trade to call
Shower runs warm, then cold when the flow is high	Water is passing through too quickly for the unit to heat it	Electrician or plumber, depending on whether the unit or flow is the issue
Low pressure light comes on and the water goes cold	Poor mains pressure, blocked filter, limescale or restricted water supply	Plumber
Power light is on but the water is cold	Failed heating element, thermostat, thermal cut-out or internal fault	Electrician
Consumer unit trips when the shower is used	Electrical fault, moisture, faulty element or circuit problem	Electrician urgently
Shower goes cold when other taps are used	Shared mains supply pressure drop	Plumber
Old shower becomes unreliable or needs repeated resets	Unit may be nearing the end of its working life	Electrician, plus a plumber if pipework changes are needed

If you are unsure, describe the full symptom when requesting quotes. “Electric shower suddenly running cold, no tripping, low pressure light on” points to a different job from “electric shower cold and RCD trips every time”.

When the problem is water flow or pressure

Electric showers need enough water pressure to work, but too much flow can also make the water cooler because the unit has less time to heat it. This is why some showers feel colder in winter, when the incoming mains water is much colder than in summer.

If the shower has been fine for months and suddenly runs cold, look for changes. Has a new appliance been fitted? Is the pressure lower at other cold taps? Does the shower only go cold when someone flushes a toilet or runs a kitchen tap? These clues point towards a plumbing or mains pressure issue rather than a failed shower heater.

Limescale can also cause trouble, especially in hard water areas. A scaled showerhead can restrict the spray pattern and affect flow through the unit. Descaling the showerhead is safe and cheap, but if the problem is inside the inlet filter or valve, a plumber should deal with it.

For water pressure, valves, leaks or supply pipe issues, compare local costs on HaMuch’s plumber rates page before booking. It helps you see realistic trade rates by area rather than relying on vague estimates.

When the problem is inside the shower unit

If water comes out at a normal rate but stays cold, the fault may be inside the shower. Common culprits include the heating element, thermostat, pressure switch, thermal cut-out or wiring within the unit.

These are not DIY parts. Electric showers draw a lot of power and sit in a bathroom environment where water and electricity are close together. A qualified electrician can test the supply safely, check whether the shower is receiving power correctly and confirm whether the unit can be repaired or should be replaced.

In some cases, replacement is more sensible than repair, especially for an older shower where parts are hard to source or several components are worn. If it is a straightforward like-for-like replacement, an electrician may be able to handle the job. If pipework needs altering, a plumber may also be required.

Before agreeing to work, ask whether the quote includes testing, fitting, certification where needed and disposal of the old unit. If you are in London, Birmingham or Manchester, the same job can vary in cost because travel time, parking, availability and local demand all affect pricing. HaMuch lets you compare electrician rates by trade and UK location, so you can check what is typical before you accept a quote.

If the shower trips the fuse box

A shower that trips the fuse box or RCD should be treated differently from a shower that simply runs cold. Tripping means the electrical system has detected a fault or unsafe condition. It could be the shower unit, the cable, the isolator, the circuit protection or moisture affecting the electrics.

Do not keep switching it back on. If it trips once and then works, you may be tempted to ignore it, but if it happens again you should stop using the shower until it has been checked.

Call an electrician and explain exactly what happens. For example, say whether it trips as soon as you pull the cord, when you press start, after a few minutes of running or only on the hottest setting. That timing helps the electrician narrow down the likely fault.

Repair or replace: how to decide

Whether to repair or replace an electric shower depends on the age of the unit, the availability of parts, the condition of the existing circuit and whether the shower is powerful enough for your household.

A small external issue, such as a scaled showerhead or reduced water pressure, may be inexpensive to sort. An internal electrical fault can be less straightforward. If the shower is old, unreliable or has already needed several repairs, a replacement may be the better long-term option.

The replacement also needs to suit the existing electrical circuit. You cannot simply fit a more powerful shower because you want better performance. The cable, protective device and installation must be suitable for the shower rating. That is why an electrician should check before any upgrade.

For landlords and property managers, the safest route is to get the shower inspected promptly, keep a record of the repair and use appropriately qualified tradespeople. A tenant reporting an electric shower suddenly running cold may be describing a comfort issue, but if tripping, burning smells or leaks are involved, it becomes a safety issue.

What affects the cost of fixing an electric shower?

HaMuch avoids vague guesswork by showing real, comparable pricing data for UK tradespeople. The final cost will still depend on what is wrong and where the property is.

Cost factor	Why it matters
Fault type	A simple flow issue is very different from an electrical fault inside the unit
Repair versus replacement	Replacement may involve fitting a new shower, testing and disposal of the old one
Access	Awkward bathrooms, tight airing cupboards or difficult cable routes can add time
Location	Rates can vary between large cities, commuter towns and smaller areas
Urgency	Same-day or out-of-hours attendance usually costs more than a planned visit
Extra trades	Some jobs need both an electrician and a plumber

When requesting quotes, give the shower make and model if you can see it safely, describe the fault in plain English and mention any tripping, leaks or pressure warnings. Photos of the shower from a normal distance can also help, but do not take anything apart to get a better picture.

Frequently asked questions

Why does my electric shower go cold after a few minutes? It may be losing heat because of low water pressure, a flow problem, limescale, a thermal cut-out or a fault inside the shower unit. If it happens repeatedly, stop using it and get it checked.

Is it my boiler if the electric shower keeps going cold? Usually not. Most electric showers heat cold mains water inside the shower unit, so the boiler is normally separate. If your hot taps work but the electric shower is cold, the shower, water supply or electrical circuit is more likely.

Can I fix an electric shower myself? You can safely check the settings, descale the showerhead and look for obvious pressure changes. You should not remove the shower cover or work on the electrics. Call an electrician for internal faults or tripping issues.

Should I call a plumber or an electrician for a cold electric shower? Call an electrician if the shower has power but no heat, trips the electrics, smells hot or seems faulty inside the unit. Call a plumber if the problem looks like low pressure, restricted flow, a leak or pipework trouble.

Can I keep using the shower if it only runs cold? If there are no electrical warning signs, using cold water briefly may not be dangerous, but it will not fix the fault. If there is tripping, leaking from the unit, buzzing, flickering lights or a burning smell, stop using it immediately.

Need the shower fixed? Compare local quotes on HaMuch

If your electric shower has suddenly started running cold, do not guess at the fault or accept the first unclear quote. Post the job on HaMuch and compare local electricians and plumbers with genuine customer reviews and transparent, comparable pricing.

For urgent warning signs such as tripping electrics, burning smells or water leaking from the shower casing, switch the shower off if safe and request an electrician as soon as possible. For pressure or water flow problems, a plumber may be the right first call. HaMuch helps you compare before you decide, with no obligation to book.

Grout Turning Black or Crumbling in the Shower

30th August 2026 Matt Warren

Black grout in a shower is common, but it is not something to ignore if the grout is also crumbling, cracking or falling out. In many homes it is simply surface mould feeding on soap residue and damp

Black grout in a shower is common, but it is not something to ignore if the grout is also crumbling, cracking or falling out. In many homes it is simply surface mould feeding on soap residue and damp air. In others, it is a sign that water is getting behind the tiles or that the seal around the shower tray has failed.

The aim is to work out which situation you have, then call the right trade before a small bathroom job turns into damaged plasterboard, loose tiles or a leak into the room below.

First, decide whether it is a cleaning issue or a repair issue

A useful starting point is the simple wipe test. If the black marks mostly come off with bathroom cleaner and the grout underneath feels hard, you are probably dealing with surface mould or staining. If the grout feels sandy, has holes in it or comes away when gently rubbed, the grout has failed and cleaning will not fix the problem.

Try these quick checks before you book anyone:

Wipe a small black patch with a suitable bathroom cleaner and see whether it lifts from the surface.
Press gently on nearby tiles. If any tile moves, sounds hollow or feels loose, stop using the shower until it has been checked.
Look at the silicone seal around the shower tray, bath edge and corners. Gaps, peeling or black staining under the seal can let water escape.
Check the ceiling or wall below the bathroom for damp marks, bubbling paint or a musty smell.
Notice whether the black marks return quickly after cleaning, as that often points to poor ventilation or constant moisture.

If water is dripping through a ceiling, running down a wall or reaching lights, switches or sockets, stop using the shower straight away. Do not touch wet electrical fittings. In that situation you may need a plumber urgently, followed by a tiler or builder once the leak has been made safe.

Why shower grout turns black

Shower grout is exposed to warm water, body oils, shampoo, soap residue and steam every day. That makes it one of the hardest working surfaces in a bathroom. Even good grout can become stained if the room stays damp for long periods.

The most common cause of black shower grout is mould growing on the surface. Bathrooms with weak extractor fans, no opening window or poor airflow give mould the damp conditions it needs. The NHS advice on damp and mould explains that mould can affect health, especially for people with allergies, asthma or weaker immune systems, so it is worth dealing with the moisture source rather than just wiping the marks away.

Black staining can also appear when grout has become porous with age. Cement-based grout is water-resistant, but it is not a complete waterproof barrier on its own. When grout cracks or wears away, water can sit behind the tile surface. Over time that can soften adhesive, damage the wall behind the tiles or create a damp smell that does not go away after cleaning.

Another common culprit is failed silicone sealant. The flexible seal around a shower tray or bath edge is there because these areas move slightly as people stand in the shower and the tray fills with water. Grout is rigid, so it often cracks in corners or edges where silicone should have been used. If the sealant is black, peeling or split, water may be slipping into the gap every time the shower runs.

Crumbling grout can also be caused by old age, poor original mixing, applying grout too thinly or cleaning with harsh acidic products. Strong descalers and abrasive scrubbing can wear grout down faster, especially in hard water areas.

Which trade should you call?

Most black or crumbling shower grout problems are a tiler job, but not always. The right person depends on what else you can see.

What you can see	Likely cause	Who usually deals with it
Black marks wipe away and grout feels solid	Surface mould, soap residue or poor ventilation	Cleaner first, then a Ventilation & AC Engineer if the extractor fan is poor
Grout is powdery, missing or cracked but tiles are firm	Failed or ageing grout	Tiler
Black sealant around the shower tray is peeling or split	Failed silicone seal	Tiler, bathroom fitter or plumber depending on the shower setup
Tiles are loose or the wall feels soft	Water has got behind the tiles	Tiler, with a plumber first if a leak is suspected
Damp patch appears below the bathroom after showering	Leak from shower waste, pipework or failed waterproofing	Plumber first, then tiler or builder for repairs

When cleaning is enough

Cleaning is a reasonable first step when the grout is intact and the black marks look like they are sitting on the surface. Use a bathroom mould remover that is suitable for tiles and grout, follow the label instructions and keep the room well ventilated. Wear gloves and never mix bleach-based products with other cleaners.

After cleaning, dry the shower area and watch what happens over the next few days. If the black staining returns almost immediately, the cleaner is only treating the symptom. The room may need better extraction, the shower may be staying wet too long or there may be water sitting behind a failing seal.

For landlords and property managers, it is sensible to keep photos before and after cleaning, note when the tenant reported the issue and arrange repairs promptly if the grout is breaking down. That paper trail helps show that you responded properly and did not treat a repair problem as ordinary cleaning.

When the shower needs regrouting

If grout is cracked, missing or crumbling, a tiler will usually remove the loose grout and replace it. This is more than cosmetic. Good grout helps shed water from the tile surface and stops dirt and moisture collecting in gaps.

Regrouting is usually suitable when the tiles are still firmly attached and the wall behind them appears sound. A tiler may also recommend replacing old silicone at the same visit, especially around the shower tray, bath edge and vertical corners. That is often the difference between a tidy-looking repair and one that actually keeps water where it belongs.

Do not simply grout over loose, wet or mouldy grout. New grout needs a clean, stable surface. If the old grout is crumbling because the wall behind the tiles is damp or the tiles are moving, a surface repair may fail again quickly.

When to suspect a hidden leak

Black grout alone does not automatically mean your shower is leaking, but crumbling grout plus damp patches is a stronger warning sign. Be more cautious if the floor outside the shower feels damp, skirting boards are swelling, paint is bubbling on the wall below or the bathroom smells musty even when dry.

A plumber is the first call if there is evidence of water escaping from pipework, the shower waste or the area under the shower tray. You can compare local plumber rates on HaMuch before booking, and if you are not sure what to look for, HaMuch also has a plain-English checklist on choosing a reliable plumber.

Once the plumbing fault is fixed, a tiler, bathroom fitter or builder may be needed to repair the wall, replace damaged boards or retile the area. The key is to fix the source of moisture before making the shower look good again.

How much could it cost to fix black or crumbling shower grout?

The cost depends on the size of the shower, how much grout needs removing, whether silicone needs replacing and whether there is hidden water damage. A small regrouting job is very different from removing loose tiles, drying the area and replacing damaged backing.

Location matters too. Labour rates can vary between smaller towns and larger cities, especially where parking, travel time and demand affect availability. Before booking a tiler in London, Birmingham or Manchester, you can use HaMuch to compare real hourly and daily rates from local tradespeople rather than relying on vague national averages.

That is where HaMuch is designed to be useful. You can see comparable pricing information, read genuine customer reviews and request quotes without being obliged to book. For a job like shower grout repair, where the visible problem may hide a leak or failed seal, comparing a few local tradespeople helps you understand who is best suited to inspect it properly.

How to stop black grout coming back

Once the grout has been cleaned or replaced, keeping the shower dry is the most effective long-term habit. Run the extractor fan during showers and for a while afterwards, or open a window where possible. Wiping down tiles with a squeegee takes less than a minute and removes much of the water that mould relies on.

Avoid leaving bottles pressed against tiled corners, as they trap moisture and soap residue. Use gentle bathroom cleaners rather than harsh acids unless the product clearly says it is safe for grout. If the silicone seal starts lifting, deal with it early. A thin gap around a tray can let in a surprising amount of water over time.

If the bathroom has persistent mould on grout, windows and walls, the issue may be ventilation rather than cleaning. A Ventilation & AC Engineer can check whether the extractor fan is suitable for the room and working as it should.

Frequently Asked Questions

Is black grout in a shower always mould? Not always. It is often surface mould or staining, but black grout can also be caused by old grout becoming porous, failed silicone, water sitting behind tiles or dirt trapped in cracked grout.

Can I just bleach black shower grout? Bleach-based bathroom products may lighten surface mould, but they will not repair cracked or crumbling grout. Always follow the product label, ventilate the room and never mix cleaning chemicals.

Who fixes crumbling grout in a shower? A tiler usually fixes crumbling grout, especially if the tiles are still firm. If there are damp patches, leaks or water damage below the bathroom, call a plumber first.

Does crumbling grout mean the shower has to be retiled? Not always. If the tiles and wall behind them are sound, regrouting may be enough. If tiles are loose or the wall is damp, some tiles may need to come off so the damaged area can be repaired properly.

Should I stop using the shower? Stop using it if grout is missing, tiles are loose, water is appearing outside the shower or there are damp marks below. If it is only light surface staining and the grout is solid, you can clean it while arranging a non-urgent check if the problem keeps returning.

Get local help before the damage spreads

If your shower grout is turning black but still solid, start with cleaning and better ventilation. If it is crumbling, cracking or letting water into gaps, it is time to get it checked by a local tiler. If there is any sign of an active leak, bring in a plumber first and avoid using the shower until it has been assessed.

You can request quotes through HaMuch and compare local tradespeople with transparent pricing, reviews and no obligation to book. Describe what you can see, mention whether the grout is black, crumbling or missing and include any damp patches nearby so the right trade can respond with a realistic quote.

Bath or Sink Draining Very Slowly

29th August 2026 Matt Warren

A bath or sink draining very slowly is one of those household problems that starts as a nuisance, then quickly becomes difficult to ignore. Water sits around your feet in the shower, the basin takes a

In most homes, the cause is a partial blockage rather than a serious plumbing fault. Hair, soap residue, food scraps, grease and general build-up can narrow the pipe until water struggles to get through. The good news is that there are a few safe things you can check before calling anyone out. The key is knowing when DIY is sensible and when it is time to call a plumber.

If only one bath, sink or basin is draining slowly, the blockage is usually close to that fixture. If several drains are slow at once, or dirty water is coming back up, treat it as more urgent and get professional help.

What to do first if your bath or sink is draining slowly

Start by using the affected bath or sink as little as possible. A slow drain can become a full blockage, especially if more water, soap, food waste or bath products keep going into it.

Before trying any fix, check whether the problem is limited to one place. Run a little water in nearby fixtures and watch how they drain. For example, if the bathroom basin is slow but the bath and toilet are normal, the issue is probably local to the basin waste. If the bath, basin and kitchen sink are all slow, the blockage may be further along the waste pipe or external drain.

Remove any obvious surface debris from the plughole. In a bathroom, hair is the usual culprit. In a kitchen, scraps of food or congealed fat can sit just below the plughole and slow the flow. Wear rubber gloves and avoid pushing anything further down.

Do not keep pouring boiling water, bleach or strong chemicals down the drain in the hope that it will clear itself. Some products can damage seals or make the job more unpleasant for a plumber. If you have already used a chemical drain cleaner, tell the plumber before they start work.

Common causes of a slow draining bath or sink

A slow draining sink or bath can have several causes, but most fall into a handful of common patterns. The table below shows what might be happening and who normally deals with it.

Symptom	Likely cause	Who to call
Bathroom basin drains slowly only	Hair, soap scum or toothpaste build-up near the plughole	Plumber
Bath or shower tray fills while in use	Hair and soap build-up in the trap or waste pipe	Plumber
Kitchen sink drains slowly after cooking or washing up	Grease, fat, food scraps or detergent residue	Plumber
Sink glugs or smells when draining	Partial blockage, poor pipe flow or air movement issue	Plumber
Several sinks, bath or shower are slow	Blockage further along the waste pipe or drain	Plumber, sometimes a drainage specialist
Dirty water comes back up into another fixture	More serious blockage or shared waste problem	Plumber urgently

For most indoor slow-drain problems, a plumber is the right first trade. They can clear local blockages, remove and clean traps, check waste pipes and advise if the issue is actually outside the property. If the problem is in a shared drain, sewer or external pipe, you may need a drainage specialist or your water company, but a plumber can usually help identify that.

If you are trying to judge whether a quote is fair, check the current plumber rates on HaMuch before booking. HaMuch shows real, comparable pricing by trade and location, so you are not relying on vague call-out estimates.

Safe fixes you can try yourself

If the water is draining slowly but not completely blocked, there are a few low-risk steps worth trying. Stop if the problem gets worse, if water starts backing up or if you are unsure how to reassemble anything you remove.

A simple plunger can work well on sinks and baths when there is a partial blockage. Make sure there is enough water to cover the rubber cup, cover any overflow opening with a damp cloth and use steady up-and-down pressure. The aim is to shift the blockage, not force the pipework apart.

For a bathroom basin or bath, a plastic drain hair remover can pull out hair near the plughole. These are cheap and can be effective, but use them gently so you do not damage the waste fitting.

For a kitchen sink, warm water with washing-up liquid may help soften grease near the plughole. Avoid pouring large amounts of fat, oil or greasy water down the sink afterwards, as it can cool and harden further along the pipe.

If you are comfortable doing so, you may be able to unscrew and clean the trap under a basin or kitchen sink. The trap is the curved section below the plughole that holds water to stop smells coming back up. Put a bowl and towel underneath first, take a photo before you undo anything and do not overtighten the fittings when you put them back.

When you should call a plumber

Call a plumber if the bath or sink is still slow after basic checks, or if the same problem keeps coming back. Repeat blockages usually mean there is build-up further along the pipe, poor pipe alignment or another issue that cannot be fixed from the plughole.

You should also get help quickly if you notice any of the following:

Water backing up into the bath, shower or another sink
A bad drain smell that does not clear after cleaning
Gurgling from other plugholes when one fixture drains
Leaking from under the sink after you have tried to clear it
Slow drainage affecting more than one room
A rental property where tenants cannot use washing or bathing facilities properly

A plumber may clear the blockage manually, remove and clean the trap, use specialist rods or check whether the waste pipe needs repair. For more complex cases, they may recommend a camera inspection or drainage contractor, especially if the blockage appears to be outside the property.

Bath, bathroom sink or kitchen sink: what the location tells you

The room where the problem happens gives useful clues.

A slow draining bath is often caused by hair and soap products collecting in the trap. This is especially common in homes where several people use the same shower over the bath. If water pools around your feet within a minute or two, the restriction is likely close to the bath waste.

A bathroom basin usually blocks with a mixture of hair, toothpaste, shaving foam and soap residue. If the plughole also smells, the trap may need cleaning. This is normally a straightforward plumbing job unless access under the basin is awkward.

A slow kitchen sink is more likely to involve grease or food waste. Even if you use hot water, fats can cool inside the pipe and stick to the sides. Over time, the opening narrows and the sink drains more slowly. If you have a washing machine or dishwasher connected to the same waste, symptoms may show up when those appliances empty.

If the toilet is also affected, or water is coming up through a shower tray when another fixture drains, do not keep testing it. That points to a more significant blockage and you should call for help.

How much does it cost to fix a slow draining sink or bath?

The cost depends on what the plumber has to do, how accessible the pipework is and whether the problem is local or further along the drainage system. A simple trap clean is usually quicker than tracing a repeated blockage behind units, under a bath panel or outside the property.

Location also affects labour rates. Plumber pricing in London, Birmingham, Manchester and surrounding areas can vary due to travel time, parking, demand and whether the job is urgent. Rather than relying on a national average that may not match your area, HaMuch lets you compare local plumbers and see transparent rate information before you request quotes.

The main factors that influence the final price are:

Whether it is a normal appointment or an emergency call-out
Whether the blockage is in one fixture or several drains
How easy it is to access the trap and pipework
Whether parts need replacing, such as a damaged trap or waste fitting
Whether specialist drainage equipment is needed

If you also have a dripping or faulty tap at the same sink, that is a separate job from the drainage issue. You can check typical repair considerations in HaMuch's guide to how much it costs to fix a leaking tap, but a slow drain itself is normally about the waste pipe rather than the tap.

Advice for landlords and property managers

For rental homes, a slow drain is worth dealing with early. Tenants may keep using the bath or sink because it still drains eventually, but the blockage can worsen and lead to leaks, smells or unusable facilities.

Ask the tenant for clear details before booking a plumber. Which fixture is affected? How long does it take to drain? Are any other sinks, baths, showers or toilets slow? Has any drain cleaner been used? A short video can also help the plumber understand the problem before arriving.

If the property is in a block of flats or converted house, ask whether neighbours have similar symptoms. Shared drainage can complicate responsibility and may involve the freeholder, managing agent or water company.

How to prevent it happening again

Once the drain is clear, small habits make a big difference. Use a hair catcher in baths and showers, wipe grease from pans with kitchen roll before washing them and avoid rinsing coffee grounds or food scraps down the sink.

Clean plugholes regularly, especially in busy bathrooms. If a sink starts to slow again within days of being cleared, do not just repeat the same DIY fix. That usually means the underlying issue has not been solved.

For older homes, recurring slow drainage can sometimes be linked to poor pipe layout, long pipe runs or previous DIY plumbing alterations. A plumber can advise whether a repair or adjustment would be more sensible than repeatedly clearing the same blockage.

Frequently Asked Questions

Why is my sink draining slowly but not blocked? It is probably partially blocked. Water can still pass through, but hair, soap, grease or food residue has narrowed the pipe so it drains much more slowly.

Can I use chemical drain cleaner for a slow draining sink? You can use products according to the label, but they are not always the best option. Never mix drain cleaners with bleach or other chemicals, and tell your plumber if you have used one.

Why does my bath drain slowly after every shower? Hair and soap residue are the most common causes. A hair catcher and regular plughole cleaning can help, but if the problem returns quickly, the blockage may be deeper in the waste pipe.

Should I call a plumber or a drainage company? For one slow sink, basin or bath, call a plumber first. If several drains are affected or the blockage appears to be outside the property, a drainage specialist may be needed.

Is a slow draining sink an emergency? Not always. If it is only slow and water is not backing up, you can usually arrange a normal plumbing visit. If dirty water is coming back up, several fixtures are affected or there is leaking, treat it as urgent.

Kitchen Extractor Fan Not Pulling Any Air Through

28th August 2026 Matt Warren

If your kitchen extractor fan is running but steam, cooking smells and smoke are still hanging around, the problem is usually airflow rather than the whole appliance being beyond repair. A fan can sound as if it is working while clogged filters, blocked ducting or a weak motor stop it pulling air through properly.

Start with the simple checks you can do safely. If those do not improve the suction, the next step is to work out whether you need a ventilation and AC engineer, an electrician or another trade. This guide explains the most common causes, what to avoid and how to describe the job when you ask for quotes.

First, check what type of extractor you have

Kitchen extractors usually work in one of two ways. A ducted extractor pulls air through the hood and sends it outside through a wall, roof or duct run. A recirculating extractor pulls air through grease and charcoal filters, then blows it back into the room.

This matters because a recirculating hood will not push air outside, even when it is working correctly. If you are expecting to feel air at an outside vent but the unit was set up to recirculate, the fan may not be faulty at all. It may simply need fresh filters and better general ventilation, such as opening a window while cooking.

Look for an outside grille on the wall, a duct going through a cupboard above the hood or a switchable setting in the manual. If you have just moved into the property, do not assume the visible hood is ducted. Many flats and rented homes use recirculating extractors because ducting to an external wall is not always practical.

Safe checks to try before calling someone

Before touching the extractor, turn it off at the switch and let it cool. Do not put fingers, cloths or tools near moving fan blades. If the unit is hardwired and you suspect an electrical fault, stop there and call an electrician.

You can still carry out a few basic checks without dismantling anything:

Check the speed setting and isolator switch: Some cooker hoods have a separate wall switch or fused spur nearby. If the lights work but the fan does not, the control or fan motor could still be faulty.
Clean the grease filters: Metal mesh filters can become packed with grease, which restricts airflow. Wash them according to the manufacturer’s instructions, often in hot soapy water or a dishwasher if suitable.
Replace charcoal filters if fitted: Recirculating extractors often use charcoal filters that lose effectiveness over time. Many manufacturers suggest changing them every few months, depending on use.
Check the outside vent from ground level: If it is safe to see the grille, look for a stuck flap, leaves, cobwebs or obvious obstruction. Do not climb ladders or remove external covers if you are unsure.
Try opening a window slightly: Extractors need replacement air to enter the room. In very airtight homes, suction can feel weak unless there is a small source of fresh air.

A simple tissue test can help, but keep it away from any moving parts. Hold a light piece of tissue near the intake grille while the fan is running. If it barely moves after the filters have been cleaned, you are likely dealing with a ducting, installation or motor issue.

Common reasons a kitchen extractor fan is not pulling air

The table below gives a practical way to match the symptom to the likely cause and the trade you may need.

What you notice	Likely cause	Who usually deals with it
Fan runs but suction is weak	Grease filters or charcoal filters are clogged	Homeowner, cleaner or appliance repairer
Fan runs but no air comes out of the outside vent	Ducting is blocked, crushed, disconnected or badly routed	Ventilation and AC engineer
Lights work but the fan does not spin	Faulty fan motor, control switch or internal connection	Electrician or appliance repairer
Fan hums, rattles or starts slowly	Motor is failing or fan blades are obstructed	Electrician or appliance repairer
Airflow drops after kitchen refit work	Ducting may have been kinked, reduced or boxed in incorrectly	Ventilation and AC engineer or kitchen fitter
Steam clears poorly in a flat or internal kitchen	Recirculating extractor is overloaded or not suitable for the room	Ventilation and AC engineer

For most airflow faults, especially where ducting is involved, a ventilation and AC engineer is usually the best first call. If the fan has no power, smells hot or the controls are faulty, compare local prices on HaMuch’s electrician rates page before booking electrical work.

Filters are the easiest problem to rule out

A blocked grease filter is one of the most common reasons an extractor fan is not working as expected. Cooking oils cool as they rise, then stick to the mesh filter. Over time, that layer of grease restricts airflow and makes the fan work harder.

If your extractor has metal filters, remove them carefully and check whether light passes through the mesh. If they feel sticky or look dark, clean them and let them dry fully before refitting. Paper, foam or charcoal filters normally need replacing rather than washing, unless the manual says otherwise.

Keeping filters clean also reduces fire risk. The London Fire Brigade includes extractor fans and filters in its advice on keeping cooking areas free from grease build-up. If you cook often, especially frying or searing, filter maintenance is not just about smells. It helps the appliance work safely and efficiently.

Ducting problems can make a working fan feel useless

If the fan sounds normal but hardly any air leaves the building, the problem may be somewhere between the hood and the outside vent. Ducting can become crushed behind cupboards, disconnected during refit work or blocked by debris at the outlet.

Long duct runs can also reduce performance, especially if they have several bends. Flexible ducting that sags or folds sharply can restrict airflow much more than homeowners expect. In some kitchens, the hood has been connected to ducting that is too narrow for the fan, making the unit noisy but ineffective.

A ventilation engineer can check whether the duct route is clear, correctly sized and safely terminated outside. If you are in London, Birmingham, Manchester or a surrounding town, labour availability and rates can vary noticeably, so it is worth comparing local tradespeople rather than accepting the first estimate.

Electrical faults need a qualified electrician

If the extractor fan is completely dead, only the light works or the fan makes a humming sound without spinning, it may be an electrical or motor fault. Cooker hoods are often connected through a fused spur or wired into the kitchen circuit, so this is not a job to guess at.

Switch the fan off if you notice any of these warning signs:

A burning smell from the hood or switch
A hot or discoloured control panel
Buzzing from the switch, fused spur or appliance
The fan cutting in and out unpredictably
Tripping electrics when the fan is turned on

An electrician can test the power supply, switch, fuse and wiring, then advise whether the fan itself needs repair or replacement. For landlords, a faulty hardwired extractor should be dealt with promptly, particularly if tenants are reporting damp, smells or electrical symptoms.

If there is any smell of gas near the hob, boiler or meter, do not use the extractor, light switches or flames. Leave the property, call the National Gas Emergency Service on 0800 111 999 and follow Gas Safe Register gas emergency advice. After the emergency has been made safe, use a Gas Safe registered engineer for gas appliance checks.

Poor installation can cause weak extraction from day one

Sometimes the extractor fan has never pulled properly. This is common after kitchen refurbishments where the visible hood looks fine but the hidden ducting is an afterthought.

A few installation issues can cause poor extraction:

The hood is too high above the hob
The duct has too many bends
The duct outlet is blocked by a flap that cannot open fully
The fan is set to recirculate when the homeowner expected external extraction
The kitchen has no easy source of replacement air
The extractor is too small for the way the room is used

A kitchen fitter may be needed if cabinets, boxing-in or the hood housing need altering. A ventilation and AC engineer is better placed to assess duct routes and airflow. An electrician may also be needed if the unit is being replaced or moved.

This is where comparing quotes helps. One tradesperson may quote to replace the hood, another may identify a simpler ducting problem. HaMuch is built to make those comparisons easier by showing real, transparent pricing and local reviews, not just a list of names with no cost context.

Should you repair or replace the extractor fan?

Repair is often sensible when the issue is a blocked duct, dirty filters, a failed switch or a loose connection. Replacement may be better if the unit is old, noisy, underpowered or needs parts that are hard to source.

If you are already planning kitchen work, it may be worth upgrading from recirculating extraction to ducted extraction where the layout allows. Ducted systems are usually better at removing moisture from cooking, which can help reduce condensation on windows, cupboards and walls. That said, not every home can be ducted easily, especially flats with internal kitchens or restrictions on external vents.

Ask the tradesperson to separate the quote into labour, parts and any making-good work. For example, replacing a built-in hood may involve electrical disconnection, fitting the new unit, adjusting a cabinet panel and checking the duct. Seeing the work broken down helps you compare quotes fairly.

What to tell the tradesperson when you ask for quotes

A clear description saves time and can help you get more accurate prices. When posting the job, include the type of extractor if you know it, whether air should vent outside and what changed before the problem started.

Helpful details include the brand and model, whether the light still works, whether the fan makes any noise, when the filters were last cleaned or replaced, and whether there is an outside grille. Photos are useful too, but take them from a normal distance rather than trying to photograph inside the appliance.

If you manage rental properties, mention whether the tenant is reporting condensation, mould, cooking smells in other rooms or a complete loss of power to the hood. These details help separate a cleaning issue from a ventilation or electrical fault.

How to avoid the same problem coming back

Once the extractor is working again, a little routine care goes a long way. Clean grease filters regularly, replace charcoal filters when needed and keep the area around the outside vent clear where it is safe to do so.

Try to use the extractor before steam builds up, not only after the kitchen is already full of moisture. Turning it on a few minutes before heavy cooking and leaving it running for a short time afterwards can help clear air more effectively. If the fan is ducted, listen for changes in noise. A sudden rattle, whistle or deeper hum can be an early sign of a loose cover, blocked duct or tired motor.

For landlords, keep a note of filter changes, repairs and tenant reports. Extractor issues can contribute to damp and mould complaints, so it is better to act early than wait until decoration, plaster or cupboards are affected.

Frequently Asked Questions

Why is my kitchen extractor fan not pulling air through? The most common causes are clogged grease filters, old charcoal filters, blocked or crushed ducting, a stuck outside vent flap or a weak fan motor. Start by cleaning or replacing filters, then call a ventilation engineer or electrician if airflow is still poor.

Who should I call if my extractor fan is not working? Call an electrician if there is no power, a burning smell, tripping electrics or faulty controls. Call a ventilation and AC engineer if the fan runs but does not pull air through or the ducting seems blocked. A kitchen fitter may be needed if cupboards or built-in housing need altering.

Can I keep cooking if the extractor fan is not working? You can usually cook with extra care if there is no electrical fault, no burning smell and no gas smell, but open windows and avoid creating lots of steam or smoke. If you smell gas, leave the property and call the National Gas Emergency Service on 0800 111 999.

How often should kitchen extractor filters be cleaned? Metal grease filters should be cleaned regularly, often monthly in busy kitchens. Charcoal filters in recirculating extractors normally need replacing every few months, but always follow the manufacturer’s instructions for your model.

Is weak suction always a sign I need a new cooker hood? No. Many suction problems are caused by dirty filters, blocked vents or poor ducting. A tradesperson can check whether the existing fan can be restored before you pay for a replacement.

Need your kitchen extractor checked?

If your kitchen extractor fan is not pulling air through after the basic filter checks, post the job on HaMuch. You can compare local tradespeople, see transparent pricing and read genuine customer reviews before deciding who to contact.

For airflow and ducting problems, ask for a ventilation and AC engineer. For power, switches, burning smells or a fan that will not spin, choose an electrician. If the issue feels urgent or unsafe, stop using the extractor and request help straight away.

Slates or Tiles Missing From the Roof After a Storm

27th August 2026 Matt Warren

If you have spotted slates or roof tiles missing after a storm, the main thing is not to panic and not to climb onto the roof. A missing tile can look small from the garden or street, but it can expos

In most cases, this is a job for a roofing contractor or a builder who carries out roof repairs. If water has reached lights, sockets or the consumer unit, you may also need an electrician. If the ceiling or plaster has been damaged, that comes later, once the roof is watertight.

This guide explains what to do now, what the damage might mean, who to call and how to compare local repair costs before booking anyone.

What to do first if roof tiles are missing after a storm

Start with safe checks from ground level. Do not go onto the roof, lean out of upstairs windows or try to refit tiles yourself. Roofs can be slippery after rain, and storm damage can leave surrounding tiles loose even if they still look attached.

Your first steps should be simple and practical:

Check the roof from the ground, the garden or the opposite side of the road if it is safe to do so.
Take clear photos of the missing slates or tiles, plus any broken pieces on the ground.
Move furniture, electrical items and valuables away from any damp ceiling areas inside.
Put a bucket or container under an active drip, but do not touch light fittings or switches if water is nearby.
Check the loft only if it is safe, well lit and you can stay on boarded areas.
Contact your insurer if you think the damage was caused by a named storm or severe weather.

If there is water coming through the ceiling near electrics, treat that as urgent. Switch off the affected circuit only if you can do so safely and without touching wet surfaces. Then contact a qualified electrician and a roof repair tradesperson. You can compare local electrician rates on HaMuch if electrical safety needs checking after water ingress.

What missing slates or tiles can mean

A roof covering is designed to overlap so rain is shed downwards and away from the structure. When a slate or tile is missing, that protective pattern is broken. Sometimes the underlay beneath the tiles will keep out light rain for a short time, but it is not meant to act as the main weatherproof layer.

Storms can also cause damage you cannot see from the ground. A tile may have blown off because it was already cracked, the fixing had corroded or the batten underneath had weakened. That is why a good tradesperson will usually check the surrounding area, not just replace one visible tile.

What you can see	Possible cause	Trade to call
One or two missing roof tiles or slates	Wind uplift, old fixings or previous cracking	Roofer or builder who handles roof repairs
Several missing tiles in one area	Wider storm damage, failed battens or loose surrounding tiles	Roofer or builder, possibly with scaffolding
Missing ridge or hip tiles	Mortar failure or storm movement along the roof peak	Roofer or builder
Damp patch on upstairs ceiling	Rain getting through the roof covering, flashing or chimney area	Roofer or builder first, plasterer later if needed
Water near light fittings	Roof leak reaching electrical fittings	Electrician urgently, plus roofer or builder
Loose guttering or fascia damage	Wind has pulled fixings away	Builder, roofer or guttering specialist

The key point is that the visible missing tile may only be the first sign. A proper inspection helps stop repeat leaks, especially before the next spell of bad weather.

Who should you call for missing roof tiles?

For most storm-related missing slates or tiles, call a roofing contractor or a builder experienced in roof repairs. On HaMuch, homeowners can compare tradespeople by location, reviews and clear local rates, rather than trying to guess what a fair price should be.

If you are in London, Birmingham, Manchester or the surrounding areas, labour rates and access costs can vary a lot from one property to another. A terraced house with restricted rear access is not the same job as a low roof on a detached home with space for ladders or scaffolding. Checking local builder rates on HaMuch gives you a clearer starting point before you request quotes.

You may need more than one trade if the storm damage has spread inside the property. The usual order is roof first, electrics if water has got near fittings, then plastering or redecoration after the affected area has dried. If the ceiling is stained, cracked or blown after the leak has been repaired, compare plasterer rates near you before arranging internal repairs.

How urgent is a missing roof tile?

A missing tile is not always an emergency in the same way as water pouring through the ceiling, but it should not be left for weeks. The risk depends on the weather forecast, how many tiles are missing and whether water is already getting inside.

If the weather is dry and only one tile has slipped, you may be able to book the repair for the next available visit. If rain is forecast, there are several missing slates or you can see daylight in the loft, ask for a prompt inspection. If water is actively entering the property, tell the tradesperson it is an active roof leak caused by storm damage.

You can also check the Met Office weather warnings if another storm is due. That can help you explain the urgency when requesting quotes and decide whether a temporary weatherproofing visit is needed before a full repair.

What affects the cost of replacing missing roof tiles?

It is difficult to give one sensible price without seeing the roof, because the visible repair can be the smallest part of the job. A straightforward replacement of a few accessible tiles is very different from storm damage on a steep roof, a third storey roofline or a chimney area that needs scaffolding.

The main cost factors are usually:

How many slates or tiles are missing, cracked or loose.
Whether matching replacement tiles are easy to source.
The height and pitch of the roof.
Whether safe ladder access is enough or scaffolding is needed.
Whether the underlay, battens, flashing, ridge tiles or chimney pointing are also damaged.
Whether it is an emergency callout after a storm.
Your location, especially in high-demand areas after severe weather.

This is where upfront comparison helps. HaMuch shows real, comparable pricing by trade and location, so you can sense-check quotes rather than relying on vague estimates. After a storm, many homeowners contact the first available tradesperson, but you can still ask for a clear breakdown of labour, materials, access equipment and any temporary weatherproofing.

Can you temporarily cover the gap yourself?

Only do what you can do safely from inside the property. If you can access the loft without stepping off boarded areas, you may be able to place a container under a drip or move stored items away from the wet area. Avoid stapling, nailing or fixing anything to roof timbers unless you know what you are doing.

Do not climb onto the roof to fit a tarpaulin, replace a tile or inspect a chimney. It may look like a quick job, but roofs are dangerous after high winds and rain. A professional will also know whether the surrounding tiles are secure enough to work around and whether extra access equipment is needed.

If broken tiles have fallen into a garden, driveway or path, move people away from the area until it has been checked. If there are loose tiles over a public pavement or shared entrance, make that clear when you request quotes so the job is treated with the right urgency.

What a tradesperson will usually check

A good roof repair visit should go beyond replacing the most obvious missing tile. The aim is to make the roof watertight and reduce the chance of the same area failing again in the next storm.

The tradesperson may check:

The surrounding tiles or slates for cracks, looseness or slipped fixings.
The condition of the battens and felt beneath the damaged area.
Ridge tiles, hip tiles and verge edges where wind damage is common.
Lead flashing around chimneys, roof windows or joins.
Gutters, fascia boards and downpipes affected by wind or falling debris.
Internal signs of water entry in the loft or top floor rooms.

Ask whether the quote includes removing broken debris, matching the replacement tiles as closely as possible and making good any small associated defects found during the repair. If the tradesperson says extra work is needed once they are on the roof, ask for photos so you can see what has changed.

What landlords and property managers should do

If a tenant reports missing roof tiles after a storm, ask for photos from a safe distance and whether there is any water inside. Do not ask tenants to inspect the roof or enter unsafe loft spaces.

For rental properties, speed matters because a small leak can quickly affect ceilings, electrics and decoration. Keep a written record of when the issue was reported, what photos were supplied, which tradespeople you contacted and any temporary measures taken. If an insurance claim is likely, those records can be useful.

It is also worth arranging the roof repair first rather than decorating straight away. Plaster and paint repairs should wait until the source of water ingress is fixed and the affected area has had time to dry.

How to describe the job when requesting quotes

The clearer your job description, the easier it is for tradespeople to respond with useful information. You do not need to diagnose the roof yourself. Just describe what you can see and what is happening inside.

Include:

The type of property, such as terraced, semi-detached, detached or flat.
The number of storeys.
Whether the missing slates or tiles are at the front, rear or side.
Whether water is coming inside now or there are only external signs.
Whether access is easy from a driveway, garden or shared area.
Photos from ground level, if you have them.
Whether you need a temporary repair, a full repair or both.

For example, you might write: "Several roof tiles are missing at the rear of a two-storey terraced house after last night’s storm. There is a damp patch on the upstairs bedroom ceiling but no active dripping at the moment. Photos attached. Please quote for inspection and repair."

That gives a tradesperson enough detail to judge urgency, likely access needs and whether they should ask follow-up questions before visiting.

Frequently Asked Questions

Can rain get in through one missing roof tile? Yes, it can. The underlay may resist some rain for a short time, but it is not designed to be the main waterproof layer. One missing tile should still be checked and repaired before more bad weather.

Is a missing roof tile an emergency? It is urgent if water is coming in, several tiles are missing, loose tiles could fall or more stormy weather is forecast. If the weather is dry and there is no internal leak, it may be a prompt repair rather than an emergency callout.

Can I replace a missing roof tile myself? It is not recommended unless you are trained and have proper roof access equipment. The fall risk is serious, and nearby tiles may also be loose after a storm.

Will home insurance cover missing roof tiles after a storm? It depends on your policy, the cause of damage and the condition of the roof before the storm. Take photos, keep invoices and contact your insurer before authorising non-urgent work if you plan to claim.

Do I need a roofer or a builder? A roofer is the most direct choice, but many builders also handle roof repairs such as replacing tiles, fixing ridge tiles and repairing storm damage. If water has reached electrics, call an electrician as well.

Should I repair the ceiling straight away? No. Fix the roof first, then allow the affected ceiling or wall to dry properly. Plastering and decorating too soon can trap moisture and lead to further staining or mould.

Get missing roof tiles repaired before the next storm

If slates or tiles are missing from your roof after a storm, act early and stay off the roof yourself. Post the job on HaMuch, add photos if you have them and compare local tradespeople with transparent rates and genuine customer reviews.

If water is coming in now, say that clearly in the job description so local roof repair tradespeople can understand the urgency. HaMuch is free for homeowners to use, and there is no obligation to book until you have compared your options and chosen the right person for the job.

Fuse Box Keeps Tripping for No Obvious Reason

25th August 2026 Matt Warren

A fuse box that trips once can be a nuisance. A fuse box that keeps tripping, especially when you cannot see an obvious reason, is your electrics asking for attention. The good news is that the trip s

A fuse box that trips once can be a nuisance. A fuse box that keeps tripping, especially when you cannot see an obvious reason, is your electrics asking for attention.

The good news is that the trip switch is doing its job. It is cutting power because something on the circuit may be unsafe, overloaded or faulty. The less good news is that repeatedly resetting it without finding the cause can make the fault harder to diagnose and, in some cases, risk damage to wiring or appliances.

Most of the time, this is a job for a qualified electrician. Before you call one, there are a few safe checks you can do from the outside, without opening the consumer unit or touching any wiring.

First, is it an emergency?

Stop trying to reset the fuse box and get help quickly if you notice any of the following:

A burning smell, smoke, sparks or crackling from a socket, switch, appliance or the fuse box area
A switch, plug, socket or cable that feels hot
Water leaking near lights, sockets, appliances or the fuse box
The same breaker trips immediately every time you switch it back on
You have had an electric shock, even a small one

If there is smoke or fire, call 999. If water is coming through a ceiling or wall near electrics, keep away from the wet area and turn off the power at the main switch only if it is safe to reach. You may need both an electrician and a plumber, because the leak has to be stopped and the electrical parts need checking before they are used again.

If the problem involves a boiler and you can smell gas, do not troubleshoot the electrics. Call the National Gas Emergency Service on 0800 111 999 immediately, then arrange a Gas Safe registered engineer when advised it is safe.

Why your fuse box trips

Most modern UK homes have a consumer unit, although many people still call it a fuse box. Inside are switches that protect different parts of the electrical system. Some switches protect a single circuit, such as upstairs lights or kitchen sockets. Others can protect several circuits at once.

A trip usually means one of three things:

Something is overloaded: Too much demand is being placed on the circuit.
Something is faulty: An appliance, cable, socket, light fitting or switch is not working safely.
Moisture is involved: Water has got into an outside light, garden socket, bathroom fitting or appliance.

A fuse box can seem to trip for no obvious reason because the trigger is not always visible. A dishwasher may only fault halfway through a cycle. An outside light may only trip when it rains. A fridge or freezer may trip when its motor starts. A heating system may trip when the programmer calls for heat.

Common causes and who normally fixes them

The table below shows the most common reasons a fuse box keeps tripping and the trade you are most likely to need.

What you notice	Likely cause	Who to call	What to do next
It trips when you use one appliance	Faulty kettle, toaster, washing machine, oven, dishwasher or similar	Appliance repair engineer or electrician	Stop using the appliance and unplug it if safe
It trips when several appliances are on	Overloaded socket circuit or too many high-power items used together	Electrician	Reduce the load and get the circuit checked if it keeps happening
It trips after rain	Water in outdoor lights, garden sockets, exterior cables or shed electrics	Electrician	Leave the affected circuit off until checked
It trips when lights are switched on	Faulty light fitting, switch, bulb holder or damaged lighting cable	Electrician	Do not remove fittings yourself
It trips when heating or hot water starts	Boiler controls, pump, programmer, immersion heater or wiring fault	Heating engineer or electrician	If there is no gas smell, note when it trips and tell the tradesperson
It trips after DIY, drilling or new shelves	Possible damaged cable in a wall or ceiling	Electrician	Stop using the affected circuit
It trips with everything unplugged	Fixed wiring fault, hidden damp, faulty consumer unit component or hard-wired appliance	Electrician	Arrange a fault-finding visit
It trips in a rental property	Any of the above, plus possible need for electrical safety records	Electrician or landlord’s managing contractor	Report it promptly and do not keep resetting it

For general household electrical faults, an electrician is usually the right first call. If the electrician finds that the fault is inside a standalone appliance, they may advise an appliance repair specialist instead. If the fault is caused by an active leak, a plumber may be needed before the electrician can safely test the affected area.

Safe checks you can do before calling an electrician

You do not need to understand electrics to gather useful information. The aim is not to repair the problem yourself. It is to narrow down what was happening when the fuse box tripped.

Start by looking at which switch has moved to the off position. If the consumer unit is labelled, write down the label, such as kitchen sockets, downstairs lights or cooker. If it is not labelled, do not guess by opening anything up. Just make a note of what lost power.

If a socket circuit has tripped, unplug appliances on that circuit. This means pulling the plug out from the wall, not just switching the appliance off. Once everything is unplugged, try resetting the switch once. If it stays on, plug appliances back in one at a time. If it trips when one appliance is plugged in or turned on, stop using that appliance.

If the switch trips again even with appliances unplugged, leave it off and call an electrician. The fault could be in the fixed wiring, a socket, an outdoor cable or a hard-wired appliance such as an oven, extractor fan, boiler, immersion heater or electric shower.

For a lighting circuit, you can safely switch lights off at the wall and replace a failed bulb if the fitting is normal and accessible. Do not remove ceiling roses, switches, downlights or bathroom fittings. A loose or damp light fitting is an electrician’s job.

You should also avoid these quick fixes:

Do not tape a trip switch in place.
Do not keep resetting the same switch over and over.
Do not use extension leads to work around a circuit that keeps tripping.
Do not remove the consumer unit cover.
Do not ignore tripping that only happens occasionally.

Electrical Safety First gives clear advice on avoiding overloaded sockets and unsafe electrical habits, which is useful if the problem seems linked to several appliances being used at once.

Why it may only trip at certain times

Random tripping is not always random. It often follows a pattern, but the pattern may not be obvious until you watch for it over a day or two.

If it happens early in the morning, the trigger could be a shower, kettle, immersion heater, storage heater or boiler timer. If it happens in the evening, it may be linked to cooking appliances, outdoor lights or several high-power items being used together. If it happens during wet weather, outdoor lighting and garden electrics move up the list of likely suspects.

Appliances with motors and heating elements can also be misleading. A washing machine might be fine during the wash stage but trip when it heats water or starts spinning. A fridge may trip only when the compressor starts. An oven may only trip once it reaches a certain temperature.

When you request a quote, include these details. A short description such as “kitchen sockets trip after the dishwasher has been on for 20 minutes” is far more helpful than “fuse box keeps tripping”. It helps the electrician plan the right tests and may reduce wasted time on site.

What an electrician will check

An electrician will usually start by asking when the tripping happens, which circuits are affected and whether any recent changes have been made. Recent work matters, even if it seems unrelated. New kitchen appliances, outdoor lighting, plastering, drilling, damp patches or rodent activity can all give clues.

They may then test the circuit, sockets, switches and connected equipment using electrical testing tools. If the issue is with fixed wiring, they can trace where the fault is likely to be. If the trip switch itself is faulty or your consumer unit is outdated, they can explain whether repair or replacement is needed.

For landlords and property managers, repeated tripping should be treated as a repair issue, not just an inconvenience for the tenant. In England, private rented properties must have electrical installations inspected and tested at least every five years under government rules. If you need a formal inspection as well as fault finding, HaMuch has a guide to the cost of an EICR landlord certificate that explains what the report covers.

How much does it cost to fix a fuse box that keeps tripping?

The cost depends on what is causing the trip. A simple fault-finding visit may be straightforward if one appliance is clearly to blame. Costs can increase if the electrician has to trace an intermittent fault, test multiple circuits, repair outdoor wiring or replace parts in the consumer unit.

Rather than relying on vague national averages, HaMuch lets you compare real electrician pricing by area. That matters because callout rates and hourly rates can vary between cities and even between nearby towns. You can compare local pricing for electricians in London, electricians in Birmingham and electricians in Manchester, as well as surrounding areas.

When asking for quotes, give the electrician enough information to price the visit sensibly. You do not need to diagnose the fault yourself, but these details help:

Information to include	Why it helps
Which switch trips, if labelled	Helps identify the affected circuit
When it trips	Points to appliances, heating, lighting or weather-related faults
Whether it trips immediately or after a delay	Helps separate fixed wiring faults from appliance faults
Recent works or new appliances	Gives clues about damaged cables or new load on a circuit
Whether there is damp, a leak or outdoor electrics	Helps the electrician prepare for water-related issues
Photos from a normal distance	Lets the electrician see the consumer unit layout without needing a close-up of wiring

Ask whether the quote includes fault finding, callout, VAT and any parts. If the job may need a second visit, ask how that will be priced. A transparent electrician should be able to explain what is included before you agree to the visit.

Can you reset the fuse box and carry on?

If it tripped once and you found an obvious cause, such as a faulty toaster that you have now unplugged, it may be reasonable to reset it and monitor the situation. If it trips again, do not keep repeating the process.

A trip switch is a safety device, not an annoyance to override. Repeated tripping means the electrical system is reacting to something. Even if the power comes back on each time, the underlying fault is still there.

This is especially important with older properties, HMOs, rental homes and houses where DIY electrical work may have been done in the past. Poorly labelled circuits, old wiring and mixed-age electrical installations can make a simple symptom harder to trace without proper testing.

Frequently Asked Questions

Why does my fuse box keep tripping when nothing is plugged in? If everything is unplugged and it still trips, the fault may be in the fixed wiring, a socket, outdoor electrics, a light fitting or a hard-wired appliance. Leave the affected circuit off and call an electrician.

Can a faulty appliance trip the whole fuse box? Yes. A faulty kettle, washing machine, oven, dishwasher, fridge or tumble dryer can trip a protective switch, especially if moisture or a heating element is involved. Stop using the appliance until it has been checked.

Is it dangerous if the fuse box keeps tripping? It can be. The trip switch is protecting you from a possible fault, overload or leakage of electricity. One trip with a clear cause may not be serious, but repeated tripping should be checked by a qualified electrician.

Who should I call if the boiler makes the fuse box trip? If there is no smell of gas, the issue may need a heating engineer, an electrician or both. Boiler controls and pumps can cause electrical trips, but the circuit supplying them may also need testing. If you smell gas, call 0800 111 999 immediately.

Should a landlord arrange an electrician for a tripping fuse box? Yes. Tenants should report repeated tripping promptly and landlords should arrange a qualified electrician or approved contractor to investigate. It may also be worth checking whether the property’s EICR is up to date.

Get an electrician to trace the fault

If your fuse box keeps tripping for no obvious reason, do the safe checks you can, then leave the affected circuit off and get it tested properly. Electrical faults are much easier to deal with when they are diagnosed calmly and correctly.

You can post your electrical job on HaMuch for free, compare local electricians, check transparent pricing and read genuine customer reviews before deciding who to contact. There is no obligation to book, so you can compare first and choose the right electrician for your home or rental property.

Black Mould Appearing Around Window Frames

25th August 2026 Matt Warren

Black mould appearing around window frames is usually a sign that moisture is collecting on cold surfaces. In many UK homes, the cause is condensation rather than a serious structural fault. That said, it is still worth dealing with properly, because mould can come back quickly if you only wipe the surface and leave the cause untouched.

The reassuring part is that the pattern of the mould often gives you useful clues. Mould on the silicone, along the bottom of the glass or in the corners of the window reveal usually points to everyday condensation and poor airflow. Mould spreading into plaster, bubbling paint or damp timber can suggest a leak, failed seal or damp problem that needs a tradesperson to investigate.

This guide explains the likely causes, what you can safely do today and which trade to call if black mould around your window frames keeps returning.

Why black mould grows around window frames

Black mould needs moisture, a food source and a surface where spores can settle. Window frames often provide all three. They are colder than the surrounding room, they collect dust and they can trap moisture behind curtains, blinds and window recesses.

In winter, warm indoor air holds more moisture. When that air touches cold glass or a cold frame, the moisture turns into condensation. If the condensation sits there for hours, especially overnight, mould can start to grow on silicone, painted timber, uPVC frames and the plaster around the window.

Common household sources of moisture include showers, cooking, drying clothes indoors, unvented tumble dryers, people breathing overnight and rooms that are kept shut for long periods. Bedrooms, bathrooms and kitchens are often the first rooms to show the problem.

The NHS explains that damp and mould can affect health, particularly for babies, older people and anyone with asthma, allergies or a weakened immune system. You do not need to panic, but you should remove mould safely and tackle the moisture source.

Quick checks before you call anyone

Before booking a tradesperson, spend a few minutes looking at where the mould is and when it appears. This can help you describe the problem clearly and avoid paying for the wrong fix.

If the mould is worst first thing in the morning, appears mainly on the glass, frame and silicone, and improves when windows are opened, condensation is the most likely cause. If the area feels damp even on dry days, paint is flaking or plaster is soft around the reveal, there may be a leak or damp issue.

Use this simple guide as a starting point:

What you notice	Most likely cause	Trade to consider
Water droplets on glass and black mould on silicone	Condensation and poor airflow	Ventilation & AC engineer, cleaner for light mould removal
Mould behind blinds or curtains but wall feels dry	Trapped moisture and poor circulation	Ventilation & AC engineer, cleaner
Peeling paint, soft plaster or damp patches around the window reveal	Damp entering around the opening	Builder or plasterer
Rotten timber frame or cracked sealant	Failed frame seal, damaged timber or poor maintenance	Carpenter & joiner, builder or window specialist
Mould below a window with damp marks from above	External leak, guttering issue or roofline problem	Builder or roofer
Mould near pipework, an upstairs bathroom or a radiator pipe route	Possible plumbing leak	Plumber

If the mould is small and clearly linked to condensation, you may be able to clean it and improve ventilation yourself. If it returns quickly, spreads into surrounding plaster or keeps the wall damp, it is time to get professional advice.

The most common causes in more detail

Condensation from everyday moisture

Condensation is the most common reason for black mould around window frames. It is especially common in well-sealed homes where old draughts have been removed but ventilation has not been improved at the same time.

You might notice condensation on bedroom windows in the morning, bathroom windows after showers or kitchen windows after cooking. If the frame is wet most days, mould has a reliable moisture supply.

A ventilation specialist can check whether extractor fans are working properly, whether trickle vents are blocked or missing and whether the room needs better background ventilation. If you want to understand likely labour costs before booking, HaMuch lets you compare local ventilation and AC engineer rates rather than relying on vague estimates.

Poor heating patterns and cold spots

Mould often appears where part of a room is colder than the rest. A window recess, external wall corner or area hidden behind heavy curtains can become a cold spot. Warm moist air then condenses there first.

This does not always mean you need a major repair. Sometimes the answer is better airflow, steadier heating and keeping curtains slightly away from the glass. In other cases, a builder may need to check for missing insulation, a badly fitted window or cold bridging around the opening.

Damaged sealant or ageing window frames

If black mould is sitting on old silicone, cracked caulk or bare timber, the surface itself may be part of the problem. Mould can become embedded in damaged sealant, so cleaning may only improve it for a short time.

Replacing mouldy silicone can help, but it should not be treated as the whole solution if the frame is constantly wet. The new sealant will go the same way unless the moisture issue is fixed.

Timber windows need extra attention. Soft wood, flaking paint or a musty smell can point to rot. A carpenter and joiner can inspect the frame and advise whether it can be repaired or needs more extensive work.

Leaks around the window opening

Sometimes mould around a window is not mainly caused by indoor condensation. Rain can enter through damaged pointing, cracked render, poor flashing, blocked gutters or gaps around the external frame.

Clues include damp that appears after rain, staining on the wall around the top or sides of the window, bubbling plaster and a patch that stays wet even when the room is ventilated. In this situation, cleaning the mould will not solve the problem because moisture is still entering the wall.

A builder can check the outside of the window opening and surrounding masonry. If the plaster has been damaged, a plasterer may be needed after the leak is fixed and the wall has dried.

Hidden plumbing leaks

Less commonly, black mould near a window can be linked to a plumbing leak, especially where there is a bathroom above, radiator pipework in the wall or a leak tracking along a ceiling or reveal.

Look for water staining, a damp smell, a patch that grows regardless of weather or condensation that seems out of proportion to normal room use. If there are signs of a leak, compare local plumber rates and get it checked before paying for cosmetic repairs.

What you can do today

For a small patch of mould on a window frame, start by reducing the moisture and cleaning the visible mould safely. Avoid dry brushing, as this can spread spores into the air. Wear gloves, ventilate the room and follow the instructions on any mould removal product you use. Never mix cleaning products, especially bleach with anything containing ammonia.

After cleaning, dry the area thoroughly. Keep an eye on how quickly the mould returns. If it reappears within days, the underlying moisture problem has not been solved.

Practical steps that often help include:

Wipe condensation from windows each morning during colder months.
Open trickle vents if your windows have them.
Use extractor fans during showers and cooking, then leave them running for a short while afterwards.
Keep bathroom and kitchen doors closed when producing steam, then ventilate those rooms directly.
Avoid drying clothes on radiators if possible.
Leave a small gap between curtains, blinds and the window frame so air can circulate.
Keep rooms heated more steadily rather than allowing them to become very cold and then heating them quickly.

If the mould covers a large area, has spread into plasterboard, keeps returning after cleaning or affects someone with breathing problems, it is sensible to call a professional rather than continuing to scrub it yourself.

When to call a tradesperson

Call a tradesperson if you are seeing more than surface mould, if the wall feels damp or if you cannot identify why the area is staying wet. You should also get help if you are a landlord or property manager and the issue is in a rental property, as mould complaints need to be handled promptly and documented properly.

The right trade depends on what the mould is telling you:

Situation	Best next step
Mould is mainly on glass, silicone and frame	Ask a ventilation specialist to assess airflow and extraction
Mould is established but surfaces are otherwise sound	A cleaner may be able to remove it safely, then ventilation still needs attention
Sealant is black, cracked or peeling	Ask a suitable tradesperson to reseal after the moisture cause is addressed
Plaster is stained, soft or blown	Builder or plasterer investigation before redecorating
Timber is soft or rotten	Carpenter and joiner inspection
There are signs of a water leak	Plumber, builder or roofer depending on the source

Try not to jump straight to repainting. Anti-mould paint can be useful once the problem is fixed, but it is not a cure for a damp wall or poor ventilation. If the surface is still wet, new paint is likely to fail.

After the cause has been repaired and the wall has dried, you may need a decorator to stain-block and repaint the area. HaMuch can help you compare painter and decorator rates so you can see local pricing before asking for quotes.

What a good tradesperson should check

A good visit should involve more than a quick look at the mould. The tradesperson should ask when the mould appears, which rooms are affected, whether condensation forms on the glass and whether the issue changes with weather.

They may check extractor fans, trickle vents, window seals, external walls, guttering, surrounding plaster and signs of leaks. They should explain whether they think the problem is condensation, water ingress or a mix of both.

Be cautious if the only recommendation is to paint over the mould without dealing with moisture. That may hide the staining for a while, but it usually does not stop it returning.

When comparing quotes, ask each tradesperson to separate investigation, repair, cleaning and decorating costs. This makes it easier to compare like for like. HaMuch is useful here because it shows real, comparable pricing by trade and location, with local reviews, so homeowners and landlords can check the market before deciding who to contact.

Advice for landlords and property managers

If black mould around window frames is reported in a rental property, deal with it as a repair and health concern rather than a housekeeping issue. Ask for clear photos, note which rooms are affected and arrange an inspection if the mould is recurring or spreading.

Landlords should check whether extractor fans work, whether windows open properly, whether seals and frames are sound and whether any structural damp or leaks are present. Tenants can help by using ventilation and reporting condensation, but they cannot fix a faulty fan, leaking frame or damp wall.

Keeping a record of reports, visits, findings and completed repairs is important. It protects the tenant, helps the landlord show the issue has been handled properly and gives future tradespeople useful context if the mould returns.

How to stop black mould returning

Long-term prevention is about keeping window areas dry enough that mould cannot thrive. That usually means balancing heating, ventilation and moisture control.

Aim to remove moisture at source where possible. Use lids on pans, run the extractor when showering, avoid drying laundry indoors without ventilation and keep air moving around window recesses. If you regularly see heavy condensation despite doing these things, your home may need better extraction or background ventilation.

It also helps to maintain the window area itself. Replace failed sealant, repair flaking paint on timber frames and fix external defects before water gets into the wall. Once the surface is dry and sound, mould-resistant products can help slow future growth, but they work best as a finishing measure, not as the main fix.

Frequently Asked Questions

Is black mould around window frames dangerous? Small areas are common in UK homes, but mould should still be removed and the cause fixed. It can aggravate asthma, allergies and respiratory conditions, so take extra care if anyone in the home is vulnerable.

Can I just clean black mould off the window frame? You can clean a small surface patch, but cleaning alone will not stop it returning if the frame keeps getting wet. If mould comes back quickly, look at ventilation, condensation, leaks or damaged sealant.

Why is mould worse around bedroom windows? Bedrooms often have closed doors, lower overnight temperatures and moisture from breathing while people sleep. That moisture condenses on cold glass and frames, especially in winter.

Who should I call for black mould around window frames? For condensation and poor airflow, start with a ventilation specialist. For damp plaster, damaged walls or external leaks, a builder or plasterer may be needed. For suspected pipe leaks, call a plumber.

Should landlords pay to fix mould around windows? If the mould is linked to disrepair, poor ventilation, faulty windows, damp or leaks, landlords should arrange appropriate repairs. Tenants should report the issue promptly and provide photos.
