Why Richmond homes get damp, mould and hidden leaks
Richmond upon Thames is one of the most desirable and historic parts of South West London, and its housing shows it. Around Richmond Green and Richmond Hill there are Georgian townhouses and grand villas, including the famous protected view over the Thames; across Kew and North Sheen the stock is largely Victorian and Edwardian terraces; and along the riverside there are mansion flats and converted period buildings. This older, high-value fabric has predictable weak points. In the Georgian and Victorian homes we most often trace leaks behind bay windows, parapet gutters and chimney breasts, penetrating damp through solid walls, and concealed pipe leaks under solid ground floors. In the riverside flats it is usually escape of water from a flat above, and in converted and rented rooms it is condensation mould. We survey and diagnose the real cause before anything is opened up.
Protecting Richmond’s period, riverside and conservation-area homes
Much of Richmond sits within conservation areas, and when a home is Georgian or riverside the last thing anyone wants is unnecessary damage to original plaster, cornicing, panelling or parquet. Our approach is non-invasive first — thermal imaging, moisture mapping and acoustic tracing to pinpoint a leak, so we open up only the exact spot that matters. Homes close to the Thames also face damp pressure from the river and periodic flood risk, so on solid period walls we distinguish carefully between rising damp, penetrating damp and condensation, because the correct fix for each is different. It all goes into a clear trace and access report you can rely on.
Mould and damp done properly in TW9 and TW10
Mould is a symptom, not the cause, so we investigate before we treat. Our team identifies whether the moisture is coming from a leak, rising or penetrating damp or condensation, and only then plans the mould treatment and any ventilation improvements. For flats and rented homes near Kew and the town centre, we also provide the independent written evidence leaseholders, landlords and managing agents need to settle who is responsible and to support an insurance claim.

Frequently asked questions — Richmond upon Thames
Can you find a leak without damaging my period features?
Yes. We use thermal imaging, acoustic listening and moisture mapping to pinpoint the leak, then open up only the precise spot, working carefully around original plaster, cornicing and parquet — which matters in Richmond’s Georgian and conservation-area homes.
My riverside flat has damp on a solid wall — is it rising damp?
Not always. Close to the Thames, damp on solid walls is often penetrating damp or condensation rather than true rising damp. We diagnose which it is before recommending any treatment.
I have a leak from the flat above — can you help?
Yes. Escape of water between flats is common in Richmond’s riverside and mansion blocks. We trace the source, establish whether it sits in your flat or the communal risers, and document it for the freeholder, managing agent and insurer.
Will my insurance pay for the work?
Trace and access may be covered under buildings insurance, depending on the policy. We provide insurance-ready reports and evidence to support the claim.
How fast can you get to Richmond?
Richmond is well within our regular South West London area, so we can usually attend TW9 and TW10 the same day, and we run genuine 24/7 emergency call-outs.
