Why Farnham homes get damp, mould and hidden leaks

Farnham is a Georgian market town famous for its architecture — the elegant townhouses of Castle Street and West Street, many of them listed and built from soft handmade Farnham bricks, sit above a stock of Victorian terraces and 1930s semis spreading out through Firgrove, Upper Hale and Rowledge. The old town centre runs down toward the River Wey, so properties on the lower ground can sit damp for longer and are more exposed to escape of water and rising damp. In the Georgian and listed homes we most often trace penetrating damp through solid walls, failed parapet and valley gutters, and slow leaks behind old panelling. We start with a proper damp survey rather than guessing.

Careful work for Farnham’s listed and period homes

A great deal of central Farnham is listed or in a conservation area, so heavy-handed work is not an option. Our engineers use thermal imaging, acoustic listening and moisture mapping for trace and access, pinpointing a leak and opening up only the spot that matters — essential in a Georgian townhouse with lime plaster and original features. Where mould has appeared in a cold room, a cellar or a poorly ventilated bathroom, we deal with the moisture source first, then treat the mould so it does not simply return.

Insurance-ready leak reports in Farnham

When a leak has already stained a ceiling or damaged a floor, the priority is clear written evidence. We trace the source non-invasively, establish exactly where it sits, and give homeowners, landlords and managing agents an insurance-ready report. Trace and access may be covered under buildings insurance, depending on the policy; we provide the reports and evidence to support the claim.

Frequently asked questions — Farnham

Can you work on a listed or Georgian home in Farnham?

Yes. Much of central Farnham is listed or in a conservation area. Our non-invasive trace and access means we open up only the spot that matters, protecting original features and lime plaster.

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 and fix the cause, then treat the mould.

How fast can you get to Farnham?

Farnham sits on our west Surrey routes near Guildford, so we can usually attend GU9 and GU10 the same day, and we run genuine 24/7 emergency call-outs.
