Leak to dry to treated, one company in Colliers Wood

Colliers Wood mixes Victorian and Edwardian terraces around the high street with 1930s semis, ex-council low-rise blocks and newer riverside flats along the Wandle. Solid brick walls with no cavity, ageing damp-proof courses and densely packed modern flats with limited through-ventilation all create the damp, poorly ventilated conditions that let black mould take hold.

Common causes of mould in Colliers Wood homes

Condensation mould in riverside and high-rise flats

The newer apartment blocks near the Wandle and Colliers Wood High Street often have sealed double glazing and limited extraction, so cooking, showering and drying laundry indoors raise moisture with nowhere to escape. Black mould builds up on bedroom walls, around window reveals and in bathrooms, worsened by proximity to the river pushing up ambient humidity.

Penetrating damp in Victorian and Edwardian terraces

Older terraced housing off the high street has solid walls, original single-skin construction and, in many cases, a failing or missing damp-proof course. Rainwater penetration through pointing, render or old sash windows drives damp into the fabric, showing up as mould patches on external walls, in alcoves and behind wardrobes and sofas pushed against cold masonry.

Past leaks and poor ventilation in 1930s and ex-council homes

Semi-detached houses and low-rise estate blocks around Colliers Wood commonly suffer roof, guttering or plumbing leaks that leave hidden pockets of damp behind plaster and under flooring. Combined with small, poorly ventilated bathrooms and north-facing bedrooms, this produces recurring black mould that keeps returning unless the original moisture source is properly traced and fixed.

What our customers say

★★★★★

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 Colliers Wood 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.
