Damp, mould & leak services in Feltham

Feltham's housing stock spans Edwardian and interwar terraces in areas like Hanworth and North Feltham, alongside a significant concentration of 1960s and 1970s local authority blocks and semi-detached homes. This mixture of older solid-wall construction, flat-roofed extensions, and ageing post-war builds creates persistent vulnerabilities to damp, mould, and water ingress.

Common damp problems in Feltham homes

Rising and Penetrating Damp in Hanworth and North Feltham Terraces

The interwar and Edwardian terraced properties common across Hanworth and North Feltham frequently lack effective or intact damp-proof courses. Ground-level moisture migrates upward through ageing brickwork, while poorly maintained pointing allows rainwater to penetrate external walls. Owners often discover damage only after internal plaster has already deteriorated significantly, making early survey work essential.

Condensation Mould in Post-War Flatted Developments

Feltham's stock of 1960s and 1970s council-era flats and maisonettes, particularly around Feltham Hill and Lower Feltham, suffers from inadequate insulation and thermal bridging at concrete junctions. These conditions encourage heavy condensation on cold surfaces, leading to persistent black mould on walls and window reveals. Poor natural ventilation in these layouts compounds the problem considerably throughout winter months.

Flat Roof and Gutter Failures Causing Hidden Leaks

Many Feltham properties, especially semi-detached and terraced homes extended during the 1970s and 1980s, feature flat-roofed rear additions with felt or built-up roofing systems now well past their serviceable life. Deteriorated membranes and blocked or sagging gutters along boundary walls allow water to track silently into ceiling voids and stud walls, where damage accumulates undetected for months before becoming visible internally.

★★★★★

I recently used a damp and mould specialist company and was extremely impressed with the service from start to finish. From the initial survey, they were knowledgeable, thorough, and took the time to clearly explain the cause of the issue rather than just treating the symptoms.

Tip: If a damp patch keeps coming back after redecorating, it is almost always a symptom, not the problem. A survey that finds the source first saves paying for the same repair twice.
