In short
Simply Filtered carries out independent mould surveys in Chiswick, from Bedford Park and Turnham Green to Strand on the Green. Duncan Ridley takes readings in your affected rooms to find what's driving the condensation and mould. He doesn't diagnose rising damp or trace leaks, and the report tells you who does.
Sound familiar?
A big, cold room and black corners.
- “Our front room is cold all winter and the corners keep going black.”
- “The ground floor of our cottage by the river always smells damp.”
- “We've been told to strip the plaster and damp-proof. Is that really needed?”
Homes in Chiswick
- Large Victorian and Edwardian houses
- Big rooms with high ceilings and solid walls take a long time to warm through. Moisture settles on cold corners, bay windows and the walls of your least-heated rooms.
- Keeping big rooms evenly warm and venting moisture where it's made usually does more than treating the walls, and changes nothing on the outside. Your report says which rooms need what.
- Riverside cottages
- Older cottages near the river have small rooms, thick walls and ground floors that stay cool, so condensation builds wherever the air hardly moves, often behind furniture and in corners.
- Your survey separates condensation from water getting in from outside, which needs drying and repair rather than more ventilation.
- 1930s semis and flats
- Mould often shows around bay windows and in bathrooms and box rooms with small windows, where steam lingers after showers and cooking, and in rooms kept shut through winter.
- This is usually a matter of better extraction and airflow in those rooms, not damp-proofing the walls themselves.
Chiswick's conservation areas include Bedford Park, Turnham Green, Grove Park and Strand on the Green, so check with Hounslow Council before changing windows or anything on the outside.
Readings taken on the visit
Nothing gets drilled or lifted. In each room you're concerned about, the visit checks:
- Humidity in your rooms
- The dew point, below which surfaces get wet
- Surface temperatures across your walls, ceilings and windows
- Airflow from any extractor fans

When you need a different specialist
If it isn't condensation, your report says who to call:
- Leaks
- Book a leak detection firm.
- Rising damp
- It's for a damp surveyor to diagnose, not your mould survey.
- River or rain water getting in
- Start with a water damage assessment.
- Removing mould
- It returns if the cause stays. Antimicrobial fogging follows once the cause is dealt with.

Questions
Questions from Chiswick
Does Strand on the Green flood?
The riverside path floods at spring tides, but property flooding there has been rare since the Thames Barrier was built. If water has got into your home, a water damage assessment comes before any mould survey.
Our Bedford Park house has its original windows. Should we replace them to stop the condensation?
Not before you know the cause. Bedford Park has extra planning controls, so check with the council before replacing windows. The survey shows whether they're part of the problem and what else would help.
Do you survey flats as well as houses in Chiswick?
Yes, flats and houses alike.
