Quick answer: If you have black mould at a property in Soho, we remove it properly and deal with the moisture driving it, rather than painting over it. 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. We start with a damp and mould survey (£500) to find the cause, then treat the mould and fix the source. Call 020 3051 8478.

Leak to dry to treated, one company in Soho

Soho's housing stock is a dense mix of converted Georgian and Victorian terraces, mansion flats above shops, restaurants and clubs, and compact studio conversions squeezed into former commercial buildings. Solid brick walls, shared flues, low ceiling heights and limited through-ventilation trap moisture from cooking, showering and street-level humidity, giving mould an easy foothold across bedrooms, bathrooms and kitchens alike.

Common causes of mould in Soho homes

Flats Above Restaurants and Kitchen Extracts

Many Soho flats sit directly above restaurant kitchens, bars and cafes, where rising heat, steam and cooking extract fumes push warm moist air upward through floors and party walls. Combined with limited natural ventilation in these converted upper storeys, this constant moisture load condenses on cooler walls and ceilings, producing persistent black mould that returns quickly unless the extraction and airflow route is addressed.

Sash Windows and Solid Brick Facades

Soho's Georgian and Victorian buildings typically have solid brick walls and original single-glazed sash windows, both prone to penetrating damp where mortar has eroded or seals have failed. Rainwater tracking through parapets, window reveals and old render allows damp patches to develop around frames and in corners, creating cold, wet surfaces where black mould readily forms in bedrooms and living spaces.

Converted Attic Flats and Cramped Rooms

Many upper-floor Soho flats were carved out of old attics and storage spaces, with sloped ceilings, small windows and little cross-ventilation. Furniture pushed against external walls in these compact rooms blocks airflow, so condensation builds unseen behind wardrobes and beds. Left untreated, this trapped moisture soaks into plaster and timber, encouraging black mould to spread across ceilings and hidden wall surfaces.

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 Soho 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.
