What you pay to deal with mould depends far more on why it's there than on the mould itself. Cleaning off a patch is relatively cheap. Fixing the leak, cold spot or ventilation problem behind it is where the real cost usually lies.

The figures below are rough national guides, last reviewed in September 2026. They are not quotes.

Typical prices

Checkatrade's 2026 cost guides give these typical figures:

  • Mould removal, one room: around £300
  • Mould removal, whole home: around £1,200
  • Hourly rate for mould removal: around £30 an hour
  • Damp survey, 2-bedroom flat: around £200
  • Damp survey, 3-bedroom terraced house: around £400
  • Damp survey, 4-bedroom detached house: around £600

Prices are usually higher in London and the South East, and urgent or same-day visits can cost extra.

What pushes the price up

  • how much of the home is affected, and whether mould has got into plaster, carpet or woodwork that needs removing
  • access, such as high ceilings, lofts or cellars
  • what's causing the moisture, and what it takes to fix it
  • making good afterwards: re-plastering and redecorating

Costs that aren't "mould removal"

Quotes for mould removal often don't include fixing the cause, which might mean:

  • a new or more powerful extractor fan
  • repairs to gutters, roofs, pointing or window seals
  • plumbing repairs
  • insulation for cold spots
  • a ventilation system for the whole home

Ask for these to be priced separately so you can compare quotes properly.

Getting good value

  1. Find out the cause first. Paying for cleaning alone usually means paying again when the mould returns.
  2. Get a written quote that says what will be done, with what, and for how much.
  3. Get more than one quote for larger jobs.
  4. Be wary of being sold an expensive damp-proof course or chemical treatment for what is really condensation, which is far more common. Ask how the cause was diagnosed.
  5. Read what any guarantee covers, and who backs it if the company stops trading.

Insurance

Home insurance may cover mould that results from something sudden, like a burst pipe, depending on your policy. Many policies exclude damage that builds up gradually or comes from wear and tear. Check your policy wording or ask your insurer before work starts.

If you rent

You shouldn't be paying to fix damp and mould caused by the building. That's normally the landlord's responsibility. See who has to fix damp and mould in a rented home.
