Quick answer: Damp & Mould Solutions UK removes and treats black mould at properties in Lewes, 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 Lewes

Lewes's housing stock is dominated by flint, brick and timber-framed cottages in Cliffe, Southover and the historic town centre, many within the conservation area, alongside Victorian terraces on the hillside streets and newer estates on the fringes. Solid walls, small windows and restricted alterations on older properties all limit airflow, making condensation and black mould a recurring problem.

Common causes of mould in Lewes homes

Solid-wall cottages and Victorian terraces

Many homes in Cliffe, Southover and Landport were built with solid brick or flint walls and no cavity, so they hold moisture rather than shedding it. Combined with small original windows and limited ventilation, warm moist air from cooking, bathing and drying washing condenses on cold internal walls, producing black mould on ceilings, in bathrooms, on bedroom walls and behind wardrobes pushed against external walls.

Listed buildings and conservation area restrictions

Lewes has a large number of listed and conservation area properties where fitting extractor fans, replacing single-glazed sash windows or adding external insulation needs consent and is often refused or delayed. Moisture from daily living gets trapped indoors with nowhere to escape, leading to persistent surface mould around window reveals, in loft spaces and in rooms with little natural ventilation, particularly through the damper autumn and winter months.

Riverside flooding and rising damp near the Ouse

Properties in Cliffe, Landport and other low-lying streets close to the River Ouse have a history of flooding and sit on ground with a high water table. Past flood water and slow-draining clay subsoil push moisture up through floors and walls, causing rising and penetrating damp that reappears behind skirting boards, under stairs and behind furniture long after any visible water has gone if the underlying source is not properly fixed.

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 Lewes 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.
