King's Lynn has a large stock of older property, and with age comes damp. Solid brick and lime-built walls, and low-lying or exposed ground, mean rising and penetrating damp are common here — and, just as often, misdiagnosed. We connect homeowners across King's Lynn, Downham Market, Hunstanton and west Norfolk with a local, insured damp specialist who finds the real cause before recommending treatment.
That matters, because the most expensive mistake in this trade is injecting a chemical damp course into a wall that never had rising damp in the first place.
Getting the diagnosis right
Damp comes in three main forms, and they need completely different fixes:
- Rising damp draws moisture up from the ground through the wall. It is less common than the industry implies, but real in older solid-wall homes without an effective damp course.
- Penetrating damp comes through the wall from outside — a failed gutter, cracked render or leaking roof. Fixing the source solves it; injecting the wall does not.
- Condensation is the most common of all, and is about ventilation and heating rather than the structure. It is also the cheapest to resolve.
A proper survey tells you which you actually have. Only then does a fixed quote make sense.
Local knowledge
King's Lynn has a remarkable stock of Hanseatic, Georgian and Victorian property around its historic quays and town centre — solid-wall brick and lime construction on low-lying ground near the Great Ouse. These older walls are prone to damp, and, just as often, to misdiagnosis.

Frequently asked questions
How much does damp proofing cost in King's Lynn?
Most treatments fall between £800 and £3,000 depending on the type of damp, how much wall is affected and whether replastering is needed. A survey is the only way to get a firm figure — misdiagnosed damp is the most common reason people overpay.
Is it definitely rising damp?
Often it is not. Many older homes are diagnosed with rising damp when the real cause is penetrating damp, a failed gutter or condensation. A good survey checks the actual cause before recommending an injected damp course, which you should be wary of anyone selling without one.
Do you treat the timbers too?
Yes. Where damp has affected skirtings, joists or roof timbers, the contractor can inspect for wet rot or woodworm and treat it as part of the works.
Will I get a report for my mortgage?
Yes. Where a lender or buyer needs it, the contractor provides a written damp report setting out the findings and any treatment.
