★★★★★ 5.0 from 20 Google reviews · trusted by Chelmsford homeowners, landlords & property managers
Quick answer: Damp & Mould Solutions UK removes and treats black mould at properties in Chelmsford, and deals with the moisture driving it rather than painting over it. Mould treatment starts from £300, with a fixed price confirmed from photos or a short video before we attend. 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. If the cause of the moisture is not clear, a full damp and mould survey is a separate service, £500, or £450 when you book online and pay the deposit. Call 020 3051 8478.

Leak to dry to treated, one company in Chelmsford

Chelmsford's housing spans Victorian and Edwardian terraces in Moulsham and Springfield, 1930s and postwar semis across Broomfield and Galleywood, and dense new-build estates at Beaulieu Park and Chelmer Village. Solid brick walls, tired render and airtight modern construction each trap moisture differently, so mould here rarely has one single cause.

Common causes of mould in Chelmsford homes

Solid-wall terraces in Moulsham and Springfield

Many of Chelmsford's older terraces around Moulsham and Springfield were built with solid brick walls and no cavity, so rain-saturated brickwork carries damp straight through to internal plaster. This penetrating damp shows as dark mould patches on chimney breasts, external-facing bedroom walls and ceilings below poorly maintained guttering, especially through wetter months.

Postwar semis with failed cavity insulation

The 1930s to 1970s semis common across Broomfield, Galleywood and Great Baddow often have cavity wall insulation that has settled, slipped or was never topped up, leaving cold bridging at corners and behind wardrobes. Combined with limited bathroom extraction, this produces recurring condensation mould on north-facing bedroom walls and behind furniture pushed against external walls.

Airtight new-builds around Beaulieu Park and Chelmer Village

Newer estates at Beaulieu Park and Chelmer Village are built to modern airtightness standards, which keeps heat in but also traps everyday moisture from cooking, showering and drying laundry indoors. Without trickle vents or extractor fans working properly, humidity builds up and settles as mould around window reveals, in en-suite bathrooms and inside built-in storage.

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 Chelmsford cost?
Mould treatment starts from £300, with a fixed price confirmed from photos or a short video before we attend. If the cause of the moisture is not clear, a full damp and mould survey is a separate service, £500, or £450 when you book online and pay the deposit. 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.
