Leak to dry to treated, one company in Hanwell

Hanwell's housing runs from Victorian and Edwardian terraces around the Uxbridge Road and Grand Union Canal to 1930s semis near Cuckoo Park and later flat conversions towards Greenford. Solid brick walls, ageing render and canal-side ground moisture leave many of these properties vulnerable to penetrating damp, while poorly ventilated bathrooms and loft conversions encourage condensation and recurring black mould.

Common causes of mould in Hanwell homes

Canal-side damp in Victorian terraces

Many Hanwell terraces near the Grand Union Canal and Hanwell Flight were built with solid brick walls and no cavity, so rainwater and ground moisture pass through easily. Where render has cracked or pointing has failed, damp tracks in behind plaster, feeding black mould on chimney breasts, external walls and ceilings that keeps returning until the entry point outside is actually repaired.

Condensation mould in 1930s semis

The semi-detached houses around Cuckoo Park and Elthorne Park typically have small bathrooms and box bedrooms with limited extraction. Daily washing, drying clothes indoors and single glazing push indoor humidity up, and without ventilation this settles as black mould around window reveals, in bathroom corners and on north-facing bedroom walls, particularly through autumn and winter.

Hidden mould in converted flats and behind furniture

Where larger Hanwell houses have been split into flats near the Uxbridge Road and station, shared plumbing, past leaks and restricted airflow between rooms raise the risk of hidden damp. Wardrobes and beds pushed against external walls trap moist air, so mould often develops unseen behind furniture before residents notice staining or a musty smell.

★★★★★

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: 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 Hanwell cost?
It depends on the cause and extent. We start with a damp and mould survey at £500 to find the moisture source, then quote the treatment. 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.
