Quick answer: Damp & Mould Solutions UK removes and treats black mould at properties in Hounslow, 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 Hounslow

Hounslow's housing spans solid-wall Victorian and Edwardian terraces around Hounslow Central and Isleworth, 1930s semis in Heston and Cranford, post-war council blocks, and dense flat conversions near the town centre and Heathrow flight paths. Older solid walls lack cavity insulation, while double glazing fitted for noise reduction often traps moisture indoors, together encouraging mould growth.

Common causes of mould in Hounslow homes

Solid-wall terraces with no cavity insulation

Many Victorian and Edwardian terraces around Hounslow Central, Isleworth and Lampton were built with solid brick walls and no cavity, so cold spots form easily on internal wall surfaces. Combined with original single-course brickwork and ageing pointing, this lets penetrating damp and condensation take hold together, producing black mould on chimney breasts, external walls and behind wardrobes pushed against cold masonry.

Flat conversions and HMOs with poor ventilation

Hounslow West, Feltham and Bedfont have numerous converted houses and flats let as multiple occupancy, often with bathrooms that have no working extractor fan and kitchens sharing a single air brick. Steam and cooking moisture cannot escape, settling on ceilings, tiled corners and window reveals, so mould reappears within weeks of cleaning unless the extraction and airflow issue is actually fixed.

Heathrow-driven double glazing trapping moisture

Properties near the Heathrow flight path in Cranford, Hounslow East and Heston are frequently fitted with secondary or acoustic double glazing to cut noise, which also seals rooms far more tightly than before. Without trickle vents or regular ventilation, humidity builds up around window frames and reveals, leading to persistent black spotting on sills, curtains and adjoining plasterwork through autumn and winter.

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 Hounslow 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.
