Damp Proofing & Mould Removal Specialists in Acton
Acton was developed almost entirely between 1880 and 1914, creating a compact stock of solid 9-inch brick terraces that are now approaching, or well past, their first century. The area’s high rate of conversion into flats — accelerated during the 1970s and 1980s — means many properties have had their original sub-floor ventilation disrupted, their DPCs bridged by raised external levels, and their moisture management fractured across multiple leasehold units. We diagnose the cause accurately — and tell you honestly what is and isn’t needed.
Why Damp & Mould Solutions
Damp Specialists Who Understand Acton’s Housing Stock
Acton sits within the London Borough of Ealing and spans five distinct neighbourhoods — North Acton, East Acton, South Acton, Acton Central, and West Acton — each with its own property character. The vast majority of residential housing is solid-brick Victorian and Edwardian. Unlike later cavity-wall construction, solid walls offer no barrier to lateral moisture movement. The South Acton estate — one of the largest post-war council redevelopments in West London — introduces a separate set of damp issues: flat-roofed blocks, thermal bridging at concrete floor-to-wall junctions, and condensation generated by poor-performing windows. We work across all property types in W3 and W4.

Our services in Acton
Damp Proofing, Surveys & Mould Removal Across Acton
We treat every common cause of damp in Acton 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 Acton
Rising damp is widespread in Acton’s solid-brick Victorian stock. Original DPCs — slate or bitumen — have passed their reliable service life. Tide marks, salt deposits, and damp lower walls up to approximately one metre are the characteristic presentation.
- 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 Acton
In Acton’s conversion flats, identifying whether damp is structural or condensation-driven is critical — the cause determines both the solution and who is responsible. We use calibrated moisture meters, boroscopes, and hygrometers to map your 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 where treatment is required
Penetrating Damp in Acton Properties
Penetrating damp — moisture entering through defective pointing, cracked render, or failed flashings — is common in Acton’s older and mid-century stock. It presents as damp patches following or during rainfall, often tracking down from parapets or chimney stacks.
- 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 Acton
Black mould in Acton flats is overwhelmingly caused by condensation and inadequate ventilation. This is particularly acute in the area’s large converted terrace flats, where cooking, bathing, and sleeping all occur in a compact footprint with limited natural ventilation.
- 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
Timber Treatment in Acton — Wet Rot, Dry Rot & Woodworm
Acton’s Victorian properties with suspended timber ground floors are at risk from sub-floor damp, particularly where air bricks have been blocked or where external ground levels have risen around the property perimeter.
- Wet rot and dry rot identification and eradication
- Woodworm treatment and preventive application
- Joist and floor repair or replacement where required
- Moisture source addressed as part of the same works

Recent work in Acton
Damp Problems We’ve Solved Across Acton
A selection of recent jobs in the Acton area, illustrating the range of causes and solutions across W3 and W4 property types.
Victorian Terrace, Acton Central — Failed DPC to Ground Floor
Hallway, front bay, and kitchen showing persistent tide marks and salt efflorescence. Survey confirmed original slate DPC had failed in solid brick construction built 1901. Chemical injection DPC applied, walls tanked and replastered with renovation render. 10-year guarantee issued.
Ground Floor Flat, W3 — Condensation Mould Misdiagnosed as Rising Damp
Tenant had been living with persistent black mould. Previous contractor had recommended full DPC injection. Our survey found no rising damp — the cause was inadequate extract ventilation and cold external walls in a poorly insulated conversion. PIV unit installed; mould treated. No structural works required.
Edwardian Terrace, South Acton — Damp Timber Floor From Blocked Vents
Musty ground floor and bouncy floorboards. Survey confirmed all sub-floor air bricks had been rendered over during a 1990s external improvement scheme. Air bricks reinstated, sub-floor void cleared. No chemical treatment needed — joists found sound on inspection.
