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

Thamesmead's housing stock is dominated by the 1960s and 70s concrete-panel estates built on reclaimed Erith Marshes, alongside deck-access maisonettes and newer Peabody-led developments around Southmere. Solid concrete construction, flat roofs and thermal bridging at wall and floor junctions make many homes prone to condensation and mould, while the area's low-lying, once-marshland ground adds persistent penetrating damp risk.

Common causes of mould in Thamesmead homes

Cold concrete walls and condensation mould

The solid concrete panel construction common across Thamesmead's estates conducts heat away from internal wall surfaces, creating cold bridging at corners, window reveals and behind wardrobes. Without added insulation, warm moist air condenses on these surfaces overnight, and black spot mould builds up on bedroom and living room walls even where residents ventilate and heat sensibly.

Flat roof and balcony leaks in maisonettes

Many Thamesmead blocks use flat roofs and open deck access balconies that were never designed for a fifty-year service life. Ageing membranes and cracked upstands let water track into ceiling voids and top-floor flats, showing up as brown staining and mould blooming across ceilings well away from the actual entry point, often mistaken for simple condensation.

Poor airflow in deck-access and low-rise flats

Deck-access flats and lower-ground maisonettes around Thamesmead often have single aspect layouts, small or sealed windows and bathrooms with no working extractor fan. Steam from cooking and showering has nowhere to escape, so it settles on tiled walls, grout and behind furniture pushed against external walls, feeding recurring mould that returns quickly after a simple wipe-down clean.

What our customers say

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 Thamesmead 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.
