Why Dorking homes get damp, mould and hidden leaks
Dorking is a Surrey Hills market town wrapped by the North Downs and Box Hill, and its housing is heavily period stock — Georgian and Victorian houses on and around the High Street, the antiques shops of West Street, and older cottages built into the greensand hillside. That greensand and the springs running off the Downs mean penetrating and rising damp are common at the lower ground levels, and homes cut into a slope often suffer lateral damp against retaining walls. In the town’s Victorian houses we regularly trace leaks from valley gutters, chimney flashings and old lead. We begin with a proper damp survey to find the real cause.
Older Dorking homes and hidden leaks
Period homes hide their leaks well — behind lime plaster, under solid floors and inside boxed-in pipework. Our engineers use thermal imaging, acoustic listening and moisture mapping for trace and access, pinpointing the source and opening up only the spot that matters, which protects the character of an older Dorking property. Where mould has appeared in a cold room or a poorly ventilated bathroom, we deal with the moisture source first, then treat the mould so it does not simply grow back.

Frequently asked questions — Dorking
Can you find a leak without damaging a period home?
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, which is important in Dorking’s older homes.
My house is built into the hillside — is that why it’s damp?
It can be. Homes cut into the greensand slopes around Dorking often get lateral and penetrating damp against retaining walls. A full survey establishes whether it is that, rising damp or a hidden leak.
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 Dorking?
Dorking is on our Surrey Hills routes, so we can usually attend RH4 the same day, and we run genuine 24/7 emergency call-outs.
