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

Kensington's housing stock is dominated by grand Victorian and Edwardian stucco-fronted terraces and mansion blocks, many long since divided into flats, alongside garden squares, mews cottages and lower ground floor conversions. Solid brick walls, single glazing and shared roofs and gutters, combined with dense conversion into smaller flats, create restricted ventilation and cold surfaces that readily encourage condensation and mould.

Common causes of mould in Kensington homes

Converted flats with poor ventilation

Many Kensington terraces were subdivided into flats decades ago, leaving internal bathrooms and kitchens with no external wall or window for natural airflow. Extractor fans are often undersized or poorly ducted, so steam and moisture linger on cold plaster. Over time this produces persistent black mould around shower enclosures, ceilings and skirting boards, particularly in smaller studio and one-bedroom conversions.

Stucco render and parapet gutter failures

The stucco-fronted facades and hidden parapet gutters typical of Kensington's period terraces are prone to hairline cracking and blocked outlets, letting rainwater track slowly into solid brick walls. This penetrating damp often surfaces well away from the original defect, appearing as mould on chimney breasts, top-floor ceilings and around window reveals long after the roofline fault first developed.

Lower ground floor and basement conversions

Lower ground floor and basement flats, common across South and West Kensington's garden squares, sit partly below street level with solid walls that struggle to stay dry. Inadequate tanking or ageing damp-proofing allows moisture to migrate inward, while limited light and airflow slow evaporation. The result is mould developing behind wardrobes, sofas and beds pushed against external walls.

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 Kensington 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.
