Leak to dry to treated, one company in Kensington and Chelsea

Kensington and Chelsea's housing stock is dominated by stucco-fronted Victorian and Georgian terraces, garden squares and mansion blocks, many split into flats with basement or lower-ground floor conversions. Solid brick walls without cavities, conservation area restrictions on external alterations and single glazing trap moisture indoors, creating ideal conditions for condensation and black mould.

Common causes of mould in Kensington and Chelsea homes

Solid-wall terraces and conservation area restrictions

Many of the borough's Victorian and Georgian terraces in Notting Hill and Chelsea have solid brick walls with no cavity, so cold spots form on north-facing rooms and behind wardrobes. Conservation area rules often restrict extractor fans, trickle vents and external wall insulation, so warm moist air from cooking, bathing and drying laundry has nowhere to escape, settling as black mould on walls and ceilings.

Basement and lower-ground floor conversions

Basement and lower-ground floor flats, common across South Kensington and Earl's Court after decades of subdivision, sit below street level and are prone to penetrating damp through retaining walls and rising damp where tanking has failed or aged. Poor natural ventilation and limited airflow behind fitted furniture allow spores to spread quickly in bedrooms, hallways and cupboards, especially once a leak has gone unnoticed.

Mansion blocks with shared roofs and communal leaks

Mansion blocks and converted flats around Earl's Court and Holland Park often share roofs, parapet gutters and downpipes maintained by freeholders or management companies, so a slow leak can take months to trace and mould appears in a bathroom or bedroom before the source is fixed. Once the leak stops, redecorating without treating the underlying moisture lets black mould return within weeks.

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 and Chelsea 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.
