Mould can start within 48 hours, so we find the source, dry the structure and treat any mould, all with one company. 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 Chesham

Chesham's housing runs from timber-framed and flint cottages in the Old Town to Victorian terraces along the River Chess, 1930s semis climbing the valley sides towards Pednor and Asheridge, and newer estates around Waterside. Solid-wall construction, a high water table on the valley floor and poorly ventilated older bathrooms all combine to make mould a recurring problem across the town.

Common causes of mould in Chesham homes

Old Town cottages and solid-wall damp

Many cottages around the Old Town and Blucher Street have solid brick, flint or timber-framed walls with no cavity, built long before damp-proof courses were standard. Moisture works through from outside or rises from the ground, and once trapped by modern plaster or retrofitted insulation it feeds black mould on internal wall surfaces, particularly in corners, behind skirtings and around old window frames.

Valley floor properties near the River Chess

Chesham sits in a narrow Chiltern valley, and homes near Waterside and the lower part of town are close to the River Chess with a naturally high water table. During wetter periods groundwater and surface water push moisture into ground floor walls and under-floor voids, driving rising and penetrating damp that shows up as mould on ceilings, skirting boards and the base of chimney breasts.

1930s semis and condensation behind furniture

The semi-detached and detached housing built up the hillside towards Pednor, Asheridge and Ley Hill often has original single glazing or later replacement windows fitted without adequate trickle ventilation. Combined with small bathrooms and bedrooms where wardrobes sit against outer walls, warm moist air condenses on cold surfaces overnight, leaving mould to develop unseen behind furniture and inside built-in cupboards.

★★★★★

I recently used a damp and mould specialist company and was extremely impressed with the service from start to finish. From the initial survey, they were knowledgeable, thorough, and took the time to clearly explain the cause of the issue rather than just treating the symptoms.

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 Chesham 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.
