In short
Simply Filtered carries out independent mould surveys across Fulham, from Parsons Green to Sands End. Duncan Ridley takes readings in each affected room to find out why condensation and mould are forming. Leaks and rising damp belong to other specialists, and the report names who to call.
Sound familiar?
Low on the walls, and a musty smell.
- “Our basement flat gets mould along the skirting every winter.”
- “The bathroom has no window and the ceiling keeps going black.”
- “My tenant says the bedroom's mouldy. Is it the flat, or how it's used?”
Homes in Fulham
- Victorian terraces
- Mould gathers where the wall is coldest: outside walls of back rooms, corners behind furniture and window reveals. Steam from showers and drying washing reaches those spots first.
- The answer is usually in the room making the moisture: a bathroom extractor that actually clears the steam, or somewhere better to dry washing.
- Houses with a lower ground floor
- The lowest floor runs cooler than the rest, so condensation shows there first, often low on the walls and in the corners by the floor.
- Those walls can also take in water from outside. Your survey works out which, so you don't pay for damp-proofing when it's condensation, or the reverse.
- Basement flats
- Below street level, moisture has fewer ways out, and in heavy rain basement flats are more likely to be hit by sewers backing up through drains and toilets.
- If that's happened, call Thames Water first. The room needs drying out before a mould survey can tell you what's going on.
About half of Hammersmith and Fulham is in conservation areas, and many Fulham streets have extra planning controls, so check with the council before changing windows, vents or anything else on the outside.
What gets measured
No drilling and no lifted floorboards. In each room that worries you, you get readings of:
- Humidity: how much moisture your air carries
- Dew point: where that moisture becomes water
- Wall, ceiling and window temperatures
- Extractor fan airflow, if you have fans

When it's not condensation
Some damp needs another trade:
- Leaks
- A leak detection company traces them.
- Rising damp
- We don't diagnose it; ask a damp surveyor.
- Flooding or a burst pipe
- Report sewer flooding to Thames Water, then book a water damage assessment.
- Getting rid of mould
- Wiping treats the surface only. Once the cause is known, antimicrobial fogging can help.

Questions
Questions from Fulham
Water came up through my basement drain. Do I need a mould survey?
Not first. Report it to Thames Water, then a water damage assessment covers drying and repair. A survey helps if mould returns once it's dry.
Is the Thames a flood risk for my Fulham home?
Very few homes are now likely to flood from the river, thanks to the Thames Barrier; heavy rain overwhelming the drains is the bigger risk. Check your address with GOV.UK's flood risk checker.
Can I fit a new extractor fan in a Fulham conservation area?
Anything that changes the outside, like a new vent on the front wall, may need permission on many Fulham streets. Ask the council first.
