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 Twickenham

Twickenham's housing stock ranges from Victorian and Edwardian terraces around St Margarets and Cross Deep to 1930s semis in Whitton and riverside mansion flats near Marble Hill. Solid brick walls without cavity insulation, converted period properties with added bathrooms, and homes close to the Thames all struggle to manage moisture, making condensation and damp-related mould a recurring problem across the area.

Common causes of mould in Twickenham homes

Solid-wall Victorian and Edwardian terraces

Streets around St Margarets, East Twickenham and Cross Deep are lined with solid brick terraces built without cavity insulation. These walls carry cold through to the internal plaster, creating cold bridging that draws condensation onto bedroom walls, chimney breasts and the corners of ceilings. Furniture pushed against external walls blocks airflow further, so mould often develops unseen behind wardrobes and headboards until it has spread.

Riverside properties and ground moisture

Twickenham's position beside the Thames means many older houses near Marble Hill and Cross Deep sit on ground that stays damp for long periods, and some lack an effective damp proof course. Rising and penetrating damp draws moisture up through walls and floors, softening plaster and skirting near ground level. Left untreated, this feeds mould growth low on walls, particularly in front rooms and hallways of older riverside homes.

Converted flats and poorly ventilated bathrooms

Many Edwardian houses in Whitton, Fulwell and Hampton Hill have been split into flats, often with bathrooms fitted into former box rooms or landings with limited or no extraction. Steam from daily showers has nowhere to escape, settling on cold windows, tiles and ceilings. Combined with shared party walls and restricted airflow between converted units, this consistently produces black mould around window frames and in bathroom corners.

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.

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 Twickenham 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.
