Quick answer: If you have black mould at a property in Epsom, we remove it properly and deal with the moisture driving it, rather than painting over it. A leak is not over when the water stops. 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 Epsom

Epsom's housing spans Edwardian and 1930s bay-fronted semis around the College Area and Woodcote Green, dense Victorian terraces near the town centre, and postwar estates towards Longmead and Horton. Solid brick walls, older single-glazed windows and converted flats with shared roofs and poor ventilation all trap moisture, giving mould a steady foothold across the borough's varied stock.

Common causes of mould in Epsom homes

Solid-wall Victorian and Edwardian terraces

Many terraces around Epsom town centre and the College Area have solid brick walls with no cavity, so they rely on breathable finishes and good airflow to stay dry. Modern paints, cement renders or poorly fitted damp-proofing trap moisture inside the wall, and it surfaces as black mould on chimney breasts, cold external corners and behind wardrobes pushed against outside walls.

1930s semis with cold, under-ventilated bathrooms

The bay-fronted semis common in Nork, Stoneleigh and Woodcote Green were built with small bathrooms tucked over side returns, often retrofitted with extractor fans that vent poorly or not at all. Steam from daily showers condenses on cold tiled walls and ceilings, feeding recurring black spot mould around windows and grout that simply painting over will not stop returning.

Converted flats and postwar estates with shared roofs

Flat conversions above shops in the town centre and postwar estate housing near Longmead and Horton frequently share roofs, lofts or party walls between units, so a slow leak or blocked gutter in one property can feed damp into a neighbour's bedroom or behind fitted furniture unnoticed. Without tracing the actual moisture source across the shared structure, surface treatments only mask the mould temporarily.

What our customers say

★★★★★

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 Epsom 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.
