Quick answer: If you have black mould at a property in Brighton, 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 Brighton

Brighton's housing runs from Regency terraces and Victorian bay-fronted properties in Hanover and Kemptown to converted seafront flats, student HMOs near Moulsecoomb and Bevendean, and 1930s semis in Patcham and Woodingdean. Solid walls, single glazing, salt-laden coastal weather and high occupancy in shared houses all combine to trap moisture, making mould a recurring issue across the city's older and denser streets.

Common causes of mould in Brighton homes

Solid-wall Victorian and Regency terraces

Streets in Hanover, Fiveways and Seven Dials are lined with solid-wall Victorian terraces and Regency townhouses that lack cavity insulation and often keep original sash windows. Without adequate ventilation, moisture from cooking, bathing and drying washing condenses on cold internal walls and ceilings, producing black mould in bedrooms, bathrooms and behind wardrobes pushed against external walls.

Seafront flats and basement conversions

Converted flats along Kemptown and Hove's seafront, including basement and lower-ground properties, face driving rain and salt spray that force penetrating damp through render and pointing. Combined with limited daylight and airflow in basement rooms, this creates persistent surface mould on walls near window reveals and skirting, which redecoration alone will not resolve while the moisture source remains active.

Shared houses and student HMOs

Moulsecoomb, Bevendean and Whitehawk contain a high concentration of shared houses and student lets, where multiple occupants, irregular heating and overcrowded rooms raise indoor humidity sharply. Mould commonly develops around window frames, in bedroom corners and behind furniture pushed against external walls, often going unnoticed until landlords or tenants spot staining or a musty smell during changeovers.

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 Brighton 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.
