Damp Proofing & Mould Removal Specialists in Mill Hill
Mill Hill’s housing spans four distinct eras: Edwardian properties on The Ridgeway and Lawrence Street, 1930s–50s detached and semi-detached across the main residential areas, and the newer Millbrook Park development. Each has different damp vulnerabilities — from failing Edwardian DPCs to cavity-wall tie corrosion in 1950s stock to condensation in energy-efficient new-build flats.
Why Damp & Mould Solutions
Damp Specialists Who Know Mill Hill Properties
Mill Hill’s 1930s and 1950s cavity-wall construction is distinctive — these properties can suffer from corroded wall ties allowing moisture to bridge the cavity. Combined with original DPCs approaching the end of their service life, this creates a specific damp pattern sometimes misidentified as penetrating damp. Newer Millbrook Park flats face condensation problems from very high thermal efficiency — low air permeability without adequate mechanical ventilation.

Our services in Mill Hill
Damp Proofing, Surveys & Mould Removal Across Mill Hill
We treat every common cause of damp in Mill Hill 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 Mill Hill
Rising damp is common across Mill Hill’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 Mill Hill
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 Mill Hill 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 Mill Hill Properties
Penetrating damp — caused by defective pointing, cracked render, damaged roofing, or leaking gutters — appears as damp patches following rainfall. Common throughout Mill Hill’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

- Ventilation assessment and fan installation
- Landlord documentation provided on request
