Leak to dry to treated, one company in Tolworth

Tolworth's housing stock ranges from 1930s semi-detached and detached bay-fronted houses along Fullers Way and Red Lion Road to the ex-council maisonettes near Tolworth Tower and post-war flats along Ewell Road. Small original bathrooms, flat-roofed extensions and solid or narrow-cavity walls make many of these homes prone to condensation and damp, and therefore black mould.

Common causes of mould in Tolworth homes

Condensation mould in 1930s semi-detached bathrooms

Many of Tolworth's inter-war semis were built with small bathrooms and no mechanical extraction, relying on a single window for ventilation. Showers and baths push moisture into the air faster than it can escape, and it settles on cold tiled walls and ceilings above the bath. Left untreated, black spotting spreads across grout lines and plaster, and the underlying warm, moist air needs addressing, not just a wipe-down, or it returns within weeks.

Cold-bridging mould around windows in Tolworth Tower flats

The concrete-framed flats around Tolworth Tower and the Broadway have solid sections of wall and metal window frames that conduct cold through to the inside face. Where warm, humid room air meets these cold bridges, condensation forms on reveals and sills, and black mould develops around window edges and in corners even when the property looks well kept. Improving ventilation and insulating the cold spots stops the cycle repeating each winter.

Penetrating damp mould in flat-roofed extensions and maisonettes

Many Tolworth homes near Hook Road and Old Malden have single-storey flat-roofed kitchen or bathroom extensions, and the ex-local authority maisonettes off Kingston Road have flat roofs too. Ageing felt or asphalt lets water track through the roof deck and down the inside of external walls, feeding mould growth behind wardrobes, sofas and beds pushed against those walls. Fixing the roof covering, not just treating the mould, is what stops it coming back.

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 Tolworth 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.
