In short

Duncan Ridley measures the rooms where mould keeps appearing to find whether condensation is the cause, and why. Rising damp and leaks are for other specialists, and your report says if the readings point that way.
Sound familiar?
It started after the new windows went in.
- “Since we replaced the windows, the bedroom walls have started going black.”
- “The bathroom mirror and window are dripping every morning.”
- “Our mansion flat's back bedroom smells musty, and the managing agent says it's us.”
Homes in Wandsworth and Putney
- Victorian and Edwardian houses
- Across Putney and Earlsfield, mould tends to start on cold outside corners, behind wardrobes and around bay windows, and in back kitchens and bathrooms where steam builds up with nowhere to go.
- Deal with the moisture where it's made first: working extraction in your kitchen and bathroom usually matters more than anything done to the walls.
- Older homes with new windows
- Draughty old windows let moisture escape. Replace them with airtight units and it stays in, settling on your coldest walls instead.
- You don't need to rip the windows out, but ventilation may need to go in with them. In a conservation area, overhauling the originals and adding secondary glazing is another route.
- Mansion flats
- With fewer outside walls and small bathrooms, moisture leaves a flat slowly, so it gathers in the coldest bedroom and behind furniture against outside walls.
- Some fixes may fall to your landlord or managing agent, so a measured report helps everyone agree what's needed instead of arguing about who's to blame.
Wandsworth has 46 conservation areas, including West Putney and Putney Embankment, so ask Wandsworth Council before changing windows or anything else on the front of your home.
What your survey records
Non-invasive: no drilling, nothing lifted. In the rooms that concern you, it records:
- Relative humidity, the share of moisture the air is holding
- Dew point, the temperature where condensation forms
- How cold your walls, ceilings and window frames get
- Whether your extractor fans move enough air

Your written report

- Readings for every room surveyed
- Photographs, and thermal images where they're useful
- The underlying cause
- Recommendations to deal with it, typically ventilation

Not condensation?
Your report points you to the right person:
- Leaks
- A leak detection company.
- Rising damp
- A damp surveyor is the right specialist; it's outside our survey.
- Flood or burst pipe damage
- A water damage assessment comes first.
- Mould removal
- Clearing mould without fixing the cause only buys time. Antimicrobial fogging can come after.

Questions
Questions from Wandsworth and Putney
We replaced our windows in Putney and now get mould. Why?
Airtight windows stop the draughts that used to carry moisture out, so it settles on your coldest walls. The survey shows where, and whether ventilation is the answer.
Is mould in a mansion flat my landlord's problem or mine?
A survey shows whether the cause is the building, how the flat is used, or both, so you and your landlord or managing agent can agree who fixes what.
Do you cover Earlsfield and Southfields too?
Yes, all of Wandsworth borough, Earlsfield and Southfields included.
