Leak to dry to treated, one company in Feltham
Feltham's housing runs from 1930s bay-fronted semis and postwar council terraces near Hanworth and Bedfont to newer flat developments around the station and Bedfont Lakes. Solid concrete and timber-frame construction from that era, combined with Heathrow flight-path noise insulation and double glazing retrofits, often traps moisture indoors, giving mould a steady foothold in older and newer homes alike.

Common causes of mould in Feltham homes
Postwar semis with solid concrete floors and cold external walls
Many Feltham streets are lined with 1930s to 1950s semis built with solid concrete ground floors and minimal cavity insulation. These cold, thermally weak walls encourage condensation to form on plaster in corners and behind wardrobes, especially in north-facing bedrooms. Left untreated, black mould spreads across skirting boards and lower wall sections, feeding on the persistent damp surface film.
Ex-council flats and maisonettes with poor cross-ventilation
Feltham has a significant stock of ex-council flats and maisonettes, particularly around Hanworth and Bedfont, where single-aspect layouts and sealed secondary glazing restrict airflow. Steam from kitchens and bathrooms has nowhere to escape, settling on ceilings and tile grout. This chronic humidity produces recurring mould around extractor fans, window reveals and bathroom ceilings that simply repainting will not resolve.
Heathrow-adjacent double glazing sealing in moisture
Homes near the Heathrow flight path, including much of Feltham and North Feltham, have often had secondary or heavy-duty double glazing fitted to cut noise, which also reduces natural draught and background ventilation. Without trickle vents or extractor upgrades, warm moist air condenses on cooler window frames and reveals overnight, encouraging black mould growth on sills, curtains and adjacent plaster that returns quickly if the glazing seal is not addressed alongside treatment.

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.
