Damp Proofing & Mould Removal Specialists in Hendon
Hendon’s housing spans Victorian terraces near the Welsh Harp, 1930s semi-detached properties throughout the centre and south, and more recent flat developments near Brent Cross. Each generation of housing brings different damp risks — failed Victorian DPCs, ageing 1930s bitumen membranes, and condensation in modern flat conversions. We identify which before recommending any treatment.
Why Damp & Mould Solutions
Damp Specialists Who Know Hendon Properties
Hendon’s proximity to the Welsh Harp and the Brent river catchment means groundwater levels in parts of NW4 are historically elevated — adding to the moisture pressure on older properties without effective DPCs. Victorian terraces near the reservoir and 1930s semis throughout Central Hendon both have original DPCs that are failing or have failed entirely.

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

Black mould in Hendon 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.

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