Leak to dry to treated, one company in Richmond upon Thames

Richmond upon Thames combines Georgian and Victorian townhouses near the river, converted flats around Richmond and Kew, and 1930s semis in Whitton and Hampton. Solid brick walls, single glazing and proximity to the Thames floodplain in Petersham and Ham leave many homes prone to condensation, penetrating damp and slow-drying moisture that feeds mould growth.

Common causes of mould in Richmond upon Thames homes

Riverside damp near the Thames

Properties close to the river in Petersham, Ham and parts of Twickenham sit on ground prone to high water tables and seasonal flooding. Solid walls without cavities draw moisture upward and inward, leaving skirting boards, lower walls and cupboards damp. Once trapped, this moisture supports black mould that keeps returning until the source is properly diagnosed and sealed.

Poor ventilation in converted flats

Many Georgian and Victorian houses in Richmond, Kew and East Sheen have been split into flats, often with bathrooms and kitchens lacking adequate extraction. Steam and daily moisture have nowhere to escape, settling on cold external walls, window reveals and ceilings. Mould frequently appears behind wardrobes and beds pushed against these walls in bedrooms.

Condensation in 1930s semis

Suburban semis across Whitton, Hampton and Teddington often retain original single-glazed windows and solid or poorly insulated cavity walls. Cold surfaces meet warm, humid indoor air, causing persistent condensation on windows and bedroom walls. Loft conversions in these homes can also trap moisture if ventilation was not properly addressed during the works.

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 Richmond upon Thames 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.
