Quick answer: Damp & Mould Solutions UK removes and treats black mould at properties in Feltham, and deals with the moisture driving it rather than painting over it. Mould treatment starts from £300, with a fixed price confirmed from photos or a short video before we attend. A leak is not over when the water stops. Mould can start within 48 hours, so we find the source, dry the structure and treat any mould, all with one company. If the cause of the moisture is not clear, a full damp and mould survey is a separate service, £500, or £450 when you book online and pay the deposit. Call 020 3051 8478.

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.

Tip: Wiping mould off with bleach and repainting hides it for a few weeks, then it returns. Mould is a moisture problem, so unless the condensation, damp or leak feeding it is fixed, it always comes back.

Frequently asked questions

How much does mould removal in Feltham cost?
Mould treatment starts from £300, with a fixed price confirmed from photos or a short video before we attend. If the cause of the moisture is not clear, a full damp and mould survey is a separate service, £500, or £450 when you book online and pay the deposit. Treating the surface without the source means the mould returns.
Is black mould in my home dangerous?
Black mould affects indoor air quality and is best removed promptly. We treat the mould and fix the moisture driving it, so the problem is dealt with at the cause.
Will the mould come back after treatment?
Not if the moisture source is fixed. We find and address the cause, whether condensation, penetrating damp or a leak, rather than just cleaning the surface.
Do you find what is causing the mould?
Yes. Every job starts by identifying why the mould is there, using a proper damp and mould survey, so the treatment lasts.
