How our coverage works

Damp, Mould & Leak Detection Ltd is based in London and covers all of Greater London, all of Surrey, Kent from the London border outwards and the RH-postcode part of West Sussex. The listings below are organised two ways: by region, council and town, and by postcode area and district. Both routes land on the same page for a place, so you can start from either.

Every location page explains what causes damp, mould, timber decay and hidden leaks in that area’s housing, what our engineers do about it, the evidence from investigations we have carried out nearby, what the written report contains and how the repairs are handled. There are no prices on these pages because every job is quoted individually once we understand the problem.
