Leak Detection, Trace & Access and Mould Treatment Across London

Our south west London coverage

South west London is the heart of what we do. Working across New Malden and Kingston, our engineers cover Kingston and Wimbledon and run right into the higher-value central patch: Clapham, Battersea, Fulham and Chelsea. It is dense, largely period and largely flatted, which brings a very particular set of leak and damp problems. Wherever you are, we diagnose the real cause first using thermal imaging, acoustic listening and moisture mapping, then open up only the spot that matters and put a clear written report behind it.

London property and the problems it brings

The south west London housing stock has three big characters, each with its own faults. The classic Victorian terraces of Clapham, Fulham and Wimbledon leak behind bay windows, in valley gutters and around chimney flashings, and their solid walls and old ground floors bring penetrating and rising damp. The area’s many mansion blocks and converted flats (huge in Chelsea, Battersea and Fulham) suffer condensation mould in cold, poorly ventilated rooms and slow concealed leaks in shared risers and old pipework. And the new riverside builds along the Thames at Battersea, Fulham and Kingston see escape of water from a flat above and condensation where mechanical ventilation is not keeping up. Guessing wastes money. We find the source, then fix it.

Escape of water between flats

Because so much of south west London is flats, a large part of our work is escape of water, where a leak in one flat shows up as a stain in another. We trace the source non-invasively, work out whether it sits in the demised flat or the communal risers, and give leaseholders, freeholders and managing agents a clear written report, the evidence needed to settle who is responsible and to support an insurance claim. Trace and access may be covered under buildings insurance, depending on the policy; we provide insurance-ready reports and evidence to support the claim.

Insurance leaks & trace and access

Trace and access may be covered under buildings insurance, depending on the policy. We provide insurance-ready reports and evidence to support the claim. Our London engineers give you the non-invasive trace, the photographs and readings, and a written report you can hand straight to your insurer or loss adjuster.

London questions we are often asked

We have a leak from the flat above. Can you help? Yes. Escape of water between flats is a lot of our south west London work. We trace the source, establish whether it is demised or communal, and document it for the leaseholder, freeholder, managing agent and insurer.

Can you find a leak without smashing the flat up? Yes. That is the point of professional leak detection. We use thermal imaging, acoustic listening and moisture mapping to pinpoint it, then open up only the spot that matters.

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.

My mould keeps coming back. Why? Because mould is a symptom. If the moisture source (a leak, condensation or damp) is not fixed, it returns. We find the cause first and set out the fix in writing, so any mould treatment that follows actually lasts.

Do you work with managing agents and blocks? Yes. We regularly report to managing agents and freeholders on flats and mansion blocks, setting out where a leak sits and providing the written evidence needed to resolve responsibility and support a claim.
