Damp, mould & leak services in Heston

Heston's housing stock is dominated by 1930s bay-fronted semis and terraces built as London expanded along the Great West Road, alongside postwar council-built estates around Heston West and Vicarage Farm and newer flat developments near Heston Road. Solid-wall interwar brick, ageing rendered elevations and flat-roofed extensions common across these properties all make penetrating damp, condensation and roof leaks persistent problems.

Mould Inspection

Find the moisture source feeding the mould, not just treat the surface. Mould inspection →

Structural Drying

Common damp problems in Heston homes

Solid-wall damp in 1930s semis

Many of Heston's bay-fronted semis and terraces off Heston Road and Vicarage Farm Road were built with solid brick walls and no cavity, so driving rain and rising groundwater penetrate more easily than in newer housing. Original render is now cracking or spalling in places, and cement-based repairs trap moisture behind the wall, leading to damp patches, blown plaster and mould around skirtings and chimney breasts.

Condensation in postwar council flats

The postwar low-rise blocks and maisonettes around Heston West and North Hyde were built with limited insulation and small kitchens and bathrooms lacking effective extraction. Combined with double glazing retrofits that sealed properties without adding ventilation, moisture from cooking, drying washing and bathing has nowhere to escape, producing black mould on north-facing walls, window reveals and behind wardrobes.

Flat-roof and extension leaks near Osterley and Spring Grove

Many Heston properties near Osterley and Spring Grove have had rear kitchen or bathroom extensions added with flat felt or asphalt roofs, a common feature of 1960s-80s home improvements in this part of west London. These roofs degrade after 15-20 years, and failed flashing where the extension meets the original brickwork lets water track down internal walls, causing staining, damp plasterboard and mould in newly built-out spaces.

★★★★★

Really impressed with the whole experience. The surveyor did a proper, thorough job and didn't rush anything, they got to the root cause of the damp and explained it all clearly. Detailed, professional and reassuring from start to finish. Couldn't recommend them more highly.

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.
