In short
Simply Filtered carries out independent mould surveys in Battersea. Duncan Ridley takes humidity and temperature readings in each affected room to show why condensation is forming. Rising damp and leaks are outside the survey, and the report tells you who to bring in.
Sound familiar?
Small rooms, steamed-up windows, black corners.
- “Our flat by the park gets mould in the bedroom corners every winter.”
- “The windows in our cottage stream with condensation every morning.”
- “Our bathroom has no window, and the ceiling won't stay clean.”
Homes in Battersea
- Mansion flats by the park
- The late Victorian mansion blocks facing Battersea Park are five storeys of flats. Mould tends to collect in your coldest bedroom, behind wardrobes and around the window frames.
- Better extraction and steady heating usually help most. Some changes may need the freeholder's say, so a report everyone can read saves arguments later.
- Workers' cottages
- The Shaftesbury Park Estate is built on the Victorian worker's cottage: low, two-storey terraced houses with small rooms, where moisture from cooking, bathing and drying clothes has little space to spread.
- Small changes, such as a fan that actually works and a better place to dry washing, can make a real difference.
- Long terraces and terrace flats
- In Park Town, some long terraces were built as flats that look like houses, and many two-storey terraces have bay windows and timber sashes. Bays and old sashes are common cold spots where condensation forms first.
- Your report says whether the windows are part of the problem before anyone suggests replacing them, which matters in a conservation area.
Battersea Park, Shaftesbury Park and Park Town are all conservation areas, so check with Wandsworth Council before changing windows or anything else on the outside.
On the survey visit
Nothing is drilled or taken up. In each room you want looked at, the survey measures:
- Relative humidity in your rooms
- Dew point, where moisture starts forming on surfaces
- Temperatures across your walls, ceilings and windows
- Extract fan airflow, if you have fans

Problems a mould survey won't solve
These need someone else, and the report says who:
- Leaks
- Bring in a leak detection company.
- Rising damp
- That's for a damp surveyor to assess.
- Water damage
- After a flood or burst pipe, book a water damage assessment.
- Mould removal
- Killing the mould without fixing the cause won't last. Antimicrobial fogging comes after the fix.

Questions
Questions from Battersea
Our mansion flat overlooks the park. Why is the bedroom mouldy?
Often because moisture from the rest of the flat settles on the coldest outside wall. The survey finds which surfaces reach dew point, and why.
Can we replace the sash windows in our Park Town house?
Park Town is a conservation area, so check with Wandsworth Council first. The survey shows whether the windows are behind the condensation at all, before you spend on new ones.
Do you cover Clapham Junction and Northcote Road?
Yes, including Clapham Junction and the Northcote Road area.
