Leak to dry to treated, one company in Willesden Green

Willesden Green's housing stock ranges from Victorian and Edwardian terraces around Mapesbury and Willesden Lane to 1930s semis near Gladstone Park and converted flats and mansion blocks close to the Jubilee line. Solid brick walls, single glazing, loft conversions and subdivided properties with shared bathrooms all restrict airflow, so condensation and black mould are common complaints for landlords and homeowners alike.

Common causes of mould in Willesden Green homes

Condensation mould in converted terraced flats

Many Edwardian and Victorian terraces around Willesden Green and Mapesbury have been split into flats with small, often windowless bathrooms and kitchens. Shared extractor systems are frequently inadequate, so steam has nowhere to go and settles on cold external walls and ceilings. Black mould builds up around shower enclosures, in bedroom corners and behind wardrobes pushed against outer walls.

Bay windows and solid walls losing heat in period conversions

The bay-fronted terraces and mansion block conversions near Brondesbury Park and Shoot-up Hill were built with solid walls and little insulation. Cold bridging at window reveals and single-glazed frames creates surfaces well below room temperature, where moist air condenses overnight. Mould commonly appears around window frames, on north-facing bedroom walls and in unheated box rooms.

Penetrating damp and past leaks in older stock near Neasden and Dollis Hill

Semi-detached houses and low-rise blocks around Dollis Hill and Gladstone Park often have ageing roofs, guttering and pointing that let water in gradually rather than in one obvious event. Once a leak has been patched, damp trapped in plaster and timber keeps feeding mould behind furniture and skirting boards unless the wall is properly dried out and the original moisture source is confirmed fixed.

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.

Was lovely working with the team and they did a fantastic and quick job to get all the mould out of my bathroom. Very much looking forward to working with them on other projects around my house!! Thank you for everything and shout out to Karim for being so sweet!

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 Willesden Green 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.
