Leak to dry to treated, one company in Hendon

Hendon's housing runs from interwar semis and mansion blocks around Church End to post-war estates at Grahame Park and West Hendon's newer regeneration flats, plus converted houses and HMOs near Middlesex University. Solid and early cavity walls, flat concrete roofs and bathrooms without extraction all trap moisture, giving black mould plenty of cold surfaces and stagnant air to establish itself on.

Common causes of mould in Hendon homes

Cold walls in interwar semis and terraces

Many Hendon streets, particularly around Church End and Cricklewood, are lined with 1930s semis built with solid or early cavity brickwork and small original windows. These walls lose heat quickly, so warm moist air condenses on external corners and behind wardrobes pushed against outside walls. Bedrooms and box rooms are frequently affected, with black spotting spreading from skirting level upward if the moisture source is not tackled.

Poorly ventilated flats and converted houses

The mansion blocks near Hendon Central and subdivided period houses close to Middlesex University often have bathrooms and kitchens without working extractor fans, and windows that are rarely opened in shared or let accommodation. Steam has nowhere to go, so it settles on tiles, ceilings and around window frames, and mould can take hold within weeks in busier households or houses in multiple occupation.

Flat roofs and penetrating damp on estate blocks

Post-war and system-built blocks at Grahame Park and parts of West Hendon have flat roofs, concrete panels and cold bridging at window reveals and balcony junctions. Where roofing or render has failed, penetrating damp tracks through the structure and shows up as mould on ceilings, in corners and behind furniture on external walls, often reappearing after redecoration unless the actual water entry point is repaired.

★★★★★

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 Hendon 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.
