Why Cobham homes get damp, mould and hidden leaks
Cobham is one of Surrey’s most affluent towns, and its housing is dominated by large detached houses — mock-Tudor family homes, modern gated developments off the Fairmile and Oxshott roads, and period cottages around Church Street and old Cobham. Big houses hide leaks well: long concealed pipe runs, underfloor heating, multiple bathrooms and complex roofs with valley gutters all give water plenty of places to travel before it shows. In rooms that are used less, we also find condensation mould where ventilation is poor. Our leak detection and damp and mould surveys find the real cause before anyone opens up a wall or lifts an expensive floor.
Leak detection in Cobham’s large, high-value homes
In a large Cobham home a small leak can run for weeks — under a solid floor with underfloor heating, behind a plant room, or from a pool or irrigation system — before a stain finally appears somewhere unexpected. Ripping up stone or engineered floors on a guess is exactly what you want to avoid. We trace the source with thermal imaging, acoustic listening and moisture mapping, pinpoint it, and open up only the spot that matters. Cobham also sits on the River Mole, so around Downside, the Tilt and Fairmile we use moisture mapping to separate genuine ground damp from a plumbing leak.
What we do in Cobham

Frequently asked questions — Cobham
I think I have an underfloor heating leak — can you find it?
Yes. Leaks on underfloor heating and long concealed pipe runs are common in Cobham’s larger homes. We trace them with thermal imaging and acoustic equipment and open up only the exact spot, rather than lifting a whole floor on a guess.
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.
Why is there mould in a room we barely use?
Because mould is a symptom of moisture. In larger homes, less-used and less-ventilated rooms cool down and condensation forms. We find and fix the moisture source, then treat the mould.
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.
