Mould removal
Proper mould removal is three jobs: cleaning the mould off, treating the surface so it's slower to return, and finding out why it grew. Skip the third and you'll be paying for the first two again next winter.
Mould and Damp doesn't remove mould. We pass your enquiry to one independent specialist who covers your area, and they quote you directly. Free, no obligation.
What the work usually involves
- A look at the cause. Condensation, a leak, rain getting in or rising damp. A specialist should say which before they start cleaning.
- Protecting the room. Covering floors and furniture, and in bigger jobs sealing the area off so spores aren't spread around the home.
- Cleaning and treating. Removing visible growth and applying a fungicidal wash. Badly affected wallpaper, sealant, silicone or plasterboard may need taking out.
- Making good. Mould-resistant paint, new sealant around baths and showers, and drying the area out.
- Stopping it coming back. A better extractor fan, a ventilation unit, a repaired gutter, or advice on heating and airing. Some of this may be priced separately.
Where it tends to grow
- Bathroom ceilings and the silicone around baths and showers.
- Bedroom corners on outside walls, especially behind beds and wardrobes.
- Window reveals and frames, where glass and frames are coldest.
- Kitchens without a working cooker hood vented outside.
- Lofts, where warm air from the house meets a cold roof.
Who should get a professional in
Small patches can usually be handled at home. Get help when the mould covers more than a small area, keeps coming back after cleaning, is on soft materials like plasterboard or carpet, or is in a home where someone has a health condition that puts them at greater risk. The government guidance linked in the questions below lists who that includes.
Landlords should bear in mind that cleaning mould without fixing the cause rarely satisfies a tenant, a council or, for social landlords, the deadlines under Awaab's Law. See the landlords' page.

These figures cover cleaning and treating the mould. Fixing the cause, such as a new fan, ventilation unit or a gutter repair, is extra. The size of the area, how far the mould has got into plaster or plasterboard, and whether anything has to be stripped out all affect the price.

Common questions
Can I remove mould myself?
Small patches on hard surfaces often can be cleaned off. The government's guidance for landlords on damp and mould and health covers how it should be dealt with. Larger areas, mould that keeps coming back, or mould in a home where someone is vulnerable are better left to a specialist who can find the cause.
Will bleach kill mould?
Bleach can lighten mould on hard, non-porous surfaces like tiles, but it doesn't reach into porous materials such as plaster or wood well, and the mould often comes back. Specialists use fungicidal treatments meant for the surface they're working on.
How long does it take?
A single room is usually a few hours. A whole property, or a job that includes stripping wallpaper, treating plaster and fitting a fan, can run to a couple of days.
Does the mould come back?
It will if the cause isn't dealt with. Treatment buys time; fixing condensation, a leak or rain penetration is what stops it for good. A specialist who only sprays and leaves isn't doing the full job.
What about mouldy furniture, clothes and carpets?
Some items can be cleaned; soft furnishings and carpets with deep mould growth often can't be saved. The specialist can tell you what's worth trying.
