Why choose our London damp surveyors
Unlike free surveys from damp-proofing companies — who profit from the treatments they recommend — an independent damp surveyor diagnoses the actual cause. London’s Victorian and Edwardian housing stock suffers from bridged damp-proof courses, raised external ground levels, blocked cavities and condensation from modern sealed windows. We inspect with calibrated moisture meters, check sub-floor timbers where accessible, and give you a costed, prioritised repair schedule.
What a damp and timber survey covers
- Identification of rising damp, penetrating damp and condensation
- Moisture profiling of affected walls and readings map
- Timber inspection for wet rot, dry rot and wood-boring insects
- Photographic evidence and a lender-acceptable written report
- Recommended remedial works with realistic costs — and what NOT to spend money on
Damp survey cost in London
An independent damp and timber survey in London typically costs £200–£400 for a flat or terraced house, depending on size and access. See our full guide to damp and timber report costs and damp survey prices across the UK.
When you need a damp survey
Book one when a mortgage valuation flags damp, before buying an older property, when you can see staining, peeling paper or smell mustiness, or when a neighbour’s building work may have affected shared walls — damp appearing after works next door can also be a party wall matter.

“Report arrived next day and the lender accepted it without question.” — buyer, Walthamstow
