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 Ewell

Ewell's housing spans Georgian and Victorian cottages around the historic village core, dense 1930s semis and terraces across Stoneleigh and Ruxley, and post-war estates in West Ewell and Ewell Court. This mix of solid-walled older properties and poorly ventilated interwar and 1950s stock means condensation, penetrating damp and old leak damage all surface regularly as mould on walls, ceilings and behind furniture.

Common causes of mould in Ewell homes

Condensation mould in 1930s semis and terraces

Stoneleigh and Ruxley are dominated by 1930s semis with small box bedrooms, single-glazed original windows in many cases, and limited trickle ventilation. Wardrobes and beds pushed against external walls trap moist air, so black mould develops behind furniture and in corners unnoticed until it has spread. Without improved airflow and insulation, redecorating alone never stops it returning.

Penetrating damp in Ewell Village's older cottages

The Georgian and Victorian cottages around Ewell Village and the High Street have solid brick walls, ageing pointing and, in some cases, no working damp proof course. Rainwater penetration and rising damp bring persistent mould to ground floor rooms and chimney breasts. Treating the visible mould without repairing the masonry, guttering or DPC leaves the underlying moisture source untouched and the problem recurs.

Bathroom and loft-related mould in West Ewell and Ewell Court estates

Post-war housing in West Ewell and Ewell Court often has flat-roofed extensions, thin loft insulation and undersized bathroom extractor fans. Steam from showers has nowhere to go, so mould builds around window frames, tiled walls and ceiling corners in bathrooms and adjoining bedrooms. Past leaks from flat roofs or plumbing add further trapped moisture, so fixing ventilation and the leak source is essential alongside any treatment.

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 Ewell 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.
