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

Mortlake's housing runs from Victorian and Edwardian terraces near the High Street and Thames Path to 1930s semis around East Sheen and riverside conversions on the old brewery site. Solid brick walls, original sash windows and older extensions without adequate ventilation make many of these homes prone to condensation and damp-related mould, particularly close to the river.

Common causes of mould in Mortlake homes

Riverside Terraces and Rising Damp

The Victorian terraces close to the Thames Path and Mortlake High Street sit on ground with a naturally high water table, and many still have solid brick walls with no cavity. Combined with ageing damp-proof courses, this allows moisture to track up through walls and skirting, feeding black mould at floor level and in unventilated corners of front rooms.

Converted Flats with Poor Ventilation

Period houses split into flats around Sheen Lane and the Mortlake conservation area often have bathrooms and kitchens without working extractor fans, sometimes converted from box rooms with little natural airflow. Steam and daily moisture build up with nowhere to escape, settling as black mould on ceilings, around window frames and behind wardrobes pushed against cold external walls.

1930s Semis with Ageing Roofs and Gutters

The semi-detached houses off Vineyard Path and towards East Sheen were built with cavity walls but are now reaching the age where roof coverings, flashings and guttering fail quietly. Water tracks in behind rendering or through cracked pointing, leaving mould stains on bedroom ceilings and around upstairs windows long before any leak becomes obvious inside.

Really impressed with the whole experience. The surveyor did a proper, thorough job and didn't rush anything, they got to the root cause of the damp and explained it all clearly. Detailed, professional and reassuring from start to finish. Couldn't recommend them more highly.

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 Mortlake 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.
