Leak to dry to treated, one company in Hersham

Hersham's housing runs from Victorian and Edwardian cottages around Hersham Green through streets of 1930s semi-detached houses to the gated estate at Burwood Park and the almshouse cottages of Whiteley Village. Older solid-wall properties suffer penetrating damp, while the many 1930s cavity-wall semis and postwar homes near Rydens trap condensation in bathrooms and bedrooms, feeding black mould.

Common causes of mould in Hersham homes

Solid-Wall Cottages Around Hersham Green

The older brick cottages near Hersham Green predate cavity wall construction, so rain and ground moisture pass straight through solid walls. Once inside, damp plaster stays cold and black mould spreads across external walls and behind wardrobes pushed against them. Treating the mould alone does not work; we trace and fix the penetrating damp source, whether failed pointing, a blocked gutter or a bridged damp-proof course, before redecorating.

1930s Semis and Condensation in Bathrooms and Bedrooms

Much of Hersham was built up with 1930s semi-detached houses, many since fitted with double glazing and loft insulation that trap warm, moist air indoors. Without adequate ventilation, condensation forms on cold spots such as window reveals, north-facing bedroom walls and bathroom ceilings, and black mould follows. We treat the affected surfaces and improve airflow and heating patterns so the moisture causing it does not build up again.

Retirement Cottages at Whiteley Village and Older Bedrooms

Whiteley Village's almshouse cottages and other older retirement homes nearby often have limited ventilation, while residents may heat and air rooms less than modern households. This combination lets moisture linger, and mould develops behind furniture, in wardrobes and around window frames unnoticed. Our surveys identify the real moisture source, from poor extraction to rising damp, and recommend fixes that respect the building while stopping mould returning.

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 Hersham 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.
