Sound familiar?
The same corner, every winter.
- “Our back bedroom goes mouldy every winter, however often I clean it.”
- “We're in a conservation area. What are we allowed to change?”
- “We've been quoted for damp-proofing. Do we actually need it?”
Homes in Ealing and Acton
- Victorian and Edwardian terraces
- Mould usually starts in your back bedroom, behind wardrobes on outside walls and around bay windows. Solid walls and corners cool quickly, and steam from cooking, showers and drying washing settles there.
- Your fix is usually better extraction in the kitchen and bathroom and more air moving through the room that suffers, not work on the walls.
- Garden suburb houses
- In cottage-style homes like those on the Brentham estate, condensation tends to form on cold window reveals and in small rooms, especially where draughts have been sealed without adding ventilation.
- Replacing windows here needs planning permission, so find out whether yours are part of the problem first. Many fixes change nothing on the outside.
- Basement and lower-ground flats
- Rooms below ground stay cool, so everyday moisture condenses on walls that sit against the earth. Water getting in from outside can look much the same.
- The readings tell the two apart, so you don't pay for ventilation when water is getting in, or for damp-proofing when it's condensation.
If your home is in one of Ealing and Acton's conservation areas, external insulation usually isn't an option, and on some estates new windows need permission. Ealing Council's conservation area pages have the details.
What the survey measures
Nothing is drilled or lifted. In each room you're worried about, the survey records:
- Relative humidity: how much moisture the air holds
- Dew point: the temperature at which it turns to water
- Surface temperatures, to find your cold spots
- Airflow from your extractor fans, where relevant

If it isn't condensation
Your report tells you who you need instead:
- A leak
- Call a leak detection company.
- Rising damp
- We don't diagnose it. You'd need a damp surveyor.
- After a flood or burst pipe
- You need a water damage assessment.
- Mould removal
- Cleaning won't last while the cause remains. Antimicrobial fogging can follow once you know it.
