Our Surrey coverage

Surrey is a large, mixed county and we work right across it. From our routes into the Guildford and Woking area in the west, through the Godalming and Cranleigh villages, across to Epsom, Leatherhead and Ashtead, and down to the Reigate and Redhill line, our engineers reach most of Surrey quickly. Whether it is a hidden leak, a damp problem or persistent mould, 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.

Surrey property and the problems it brings

Surrey’s housing runs the full range, and each type has its own weak points. Period village cottages in places like Cranleigh, Shalford and Ripley bring solid walls, old chimney breasts and low ground levels, so we see rising and penetrating damp and slow leaks under solid floors. The Victorian and Edwardian town stock in Guildford, Reigate and Epsom tends to leak behind bay windows, valley gutters and around chimney flashings. The county’s many 1930s semis suffer cold-wall condensation, blocked cavities and failed bathroom seals feeding hidden leaks. And the new-build flats and riverside apartments around Woking, Redhill and the Kingston border see escape of water from a flat above and condensation mould where ventilation is poor. Guessing wastes money. We find the source, then fix it.

Insurance-ready reports for Surrey claims

A lot of Surrey work involves a leak that has already caused damage: a stained ceiling, a ruined floor, or water showing up between flats. We trace the source non-invasively, establish exactly where it sits, and give homeowners, landlords and managing agents the clear written evidence they need. Trace and access may be covered under buildings insurance, depending on the policy; we provide insurance-ready reports and evidence to support the claim.

What we do in Surrey

Leak detection

Thermal imaging, acoustic and moisture tracing to pinpoint a hidden leak before any wall comes down.

Emergency & burst pipes

Urgent cases are prioritised when water is coming through a ceiling or a pipe has burst.

Trace & access (insurance)

We find and expose the leak and document it for your escape-of-water claim.

Mould treatment & investigation

We find the moisture source, treat the mould and stop it returning, with a written report.

Insurance-ready reports

Clear, evidenced reports written for insurers, solicitors and managing agents.

Damp & mould surveys

A proper diagnosis (condensation, penetrating or rising damp) so you fix the right thing once.

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 Surrey 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.

Surrey questions we are often asked

Do you cover the whole of Surrey? Yes. Our engineers and surveyors work right across the county, from Guildford and Woking in the west through to Reigate, Redhill and the south west London border.

Can you find a leak without smashing the house 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.

How quickly can you get to me in Surrey? It depends where you are: call 0800 054 1524 for the earliest available appointment; urgent leaks are prioritised.
