Damp Proofing & Mould Removal Specialists in Willesden
Willesden’s housing was built in a concentrated period between 1880 and 1910, producing a uniform stock of two-storey Victorian terraces that are now over 100 years old. Original DPCs have failed or are failing; sub-floor ventilation has been compromised through decades of alteration; and the area’s high density of conversion flats means individual units are often unable to manage their own moisture independently. We diagnose accurately — and tell you honestly what is and isn’t needed.
Why Damp & Mould Solutions
Damp Specialists Who Know Willesden Properties
Willesden Green, Willesden Junction, and the surrounding streets were developed as one of London’s first commuter suburbs. These properties were built as solid 9-inch brick construction (no cavity) with original DPCs — slate or bitumen — that have now passed their reliable service life by several decades. Blocked air bricks are among the most common causes of damp we identify in Willesden. Commercial units on Willesden Lane frequently have concrete floors with no DPC.

- 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 Willesden Properties
Penetrating damp — caused by defective pointing, cracked render, damaged roofing, or leaking gutters — appears as damp patches following rainfall. Common throughout Willesden’s period and post-war stock.

- External masonry repair, pointing, and waterproof coatings
- Internal tanking where required
- No surface-only treatments without root-cause repair
