Damp Proofing & Mould Removal Specialists in Hampstead
Hampstead has some of the most challenging damp conditions in North London. Heavy London clay on the Hampstead Ridge retains moisture at extreme levels; Georgian and Victorian basements that were never designed as habitable rooms now house thousands of residents; and high-value period properties are frequently extended downward, bringing new ground contact. We have the specialist knowledge these properties demand.
Why Damp & Mould Solutions
Damp Specialists Who Know Hampstead Properties
Hampstead’s Georgian and Victorian stock is exceptional — and exceptionally damp-prone. The Heath’s clay soils sit at near-saturation for most of the year. Basement conversions here are among the most technically demanding residential damp projects we undertake. We also survey a significant volume of high-value pre-purchase properties where accurate diagnosis has major financial implications.

Our services in Hampstead
Damp Proofing, Surveys & Mould Removal Across Hampstead
We treat every common cause of damp in Hampstead residential and commercial properties. Each service begins with a proper diagnosis — we don’t recommend treatment until we know the cause.
Rising Damp Treatment in Hampstead
Rising damp is common across Hampstead’s older housing stock — particularly pre-1940 properties where original DPCs have failed or are absent. It presents as tide marks, salt deposits, and damp lower walls up to around one metre.
- Chemical DPC injection — CSRT-specified method
- Tanking and replastering with damp-resistant render
- 10-year guarantee on completed works
- Salt removal and finishing included
Damp Survey in Hampstead
A professional damp survey is the only reliable way to distinguish rising damp from penetrating damp or condensation. We use calibrated moisture meters, boroscopes, and hygrometers to map your Hampstead property accurately.
- CSRT-qualified surveyor — independent, not sales-led
- Written report with photographs and moisture readings
- Suitable for home purchases, mortgage requirements, and insurance
- Fixed-price quotation provided where treatment is required
Penetrating Damp in Hampstead Properties
Penetrating damp — caused by defective pointing, cracked render, damaged roofing, or leaking gutters — appears as damp patches following rainfall. Common throughout Hampstead’s period and post-war stock.
- Source identified before any treatment is carried out
- External masonry repair, pointing, and waterproof coatings
- Internal tanking where required
- No surface-only treatments without root-cause repair
Mould Removal & Condensation Control in Hampstead
Black mould in Hampstead flats and converted houses is almost always caused by condensation and inadequate ventilation — not structural damp. We treat the mould and address the root cause so it doesn’t return.
- Professional mould removal and anti-fungal treatment
- Positive input ventilation (PIV) for whole-home humidity control
- Ventilation assessment and fan installation
- Landlord documentation provided on request
