Leak to dry to treated, one company in Mitcham

Mitcham's housing spans Victorian and Edwardian terraces around Cricket Green, 1930s bay-fronted semis near Pollards Hill, and postwar council low-rise around Phipps Bridge and Eastfields. Many older properties have failed or bridged damp-proof courses and solid brick walls, while converted terraces and flats above shops often lack adequate extraction, leaving both prone to condensation and rising damp that feed black mould.

Common causes of mould in Mitcham homes

Solid-wall Victorian terraces around Cricket Green and Lower Mitcham

The older terraced streets near Cricket Green and Lower Mitcham were built with solid brick walls and no cavity, so they rely on a sound damp-proof course and lime-based plaster to stay dry. Where paths or flowerbeds have been raised above the DPC, or repointing has used hard cement, moisture tracks up internal walls and shows as black mould at skirting height and behind wardrobes on external walls.

Poorly ventilated flats and conversions near Mitcham Junction

Many Edwardian houses near Mitcham Junction and Figges Marsh have been split into flats, often with bathrooms and kitchens fitted into small internal rooms with no window or working extractor fan. Cooking and shower steam has nowhere to go, condensing on cold walls and ceilings, and mould develops around window reveals, in corners and behind furniture pushed against external walls where air cannot circulate.

Postwar council stock at Pollards Hill and Phipps Bridge

The concrete and system-built homes around Pollards Hill and Phipps Bridge were designed with different heating assumptions and can suffer cold bridging through concrete panels and lintels. Combined with double glazing that traps moisture indoors, this produces persistent condensation on external walls and around window frames, with black mould reappearing in bedrooms and behind fitted furniture even after redecoration unless the underlying cold spots and ventilation are addressed.

What our customers say

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 Mitcham 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.
