Leak to dry to treated, one company in Golders Green

Golders Green mixes substantial Edwardian and 1920s-30s semi-detached houses, the Arts and Crafts terraces of neighbouring Hampstead Garden Suburb, and mansion blocks along Golders Green Road, many now converted into flats. Solid brick walls without cavities, ageing sash windows and lofts converted without adequate ventilation all trap moisture, making condensation and black mould persistent problems across the area's older housing stock.

Common causes of mould in Golders Green homes

Solid-wall Edwardian houses and cold-bridging mould

Many Golders Green streets are lined with Edwardian and Victorian solid-brick houses with no cavity insulation. Internal wall surfaces run cold, especially at corners, behind wardrobes and above skirting boards, and warm moist air condenses on contact. This produces black speckled mould on bedroom and living room walls that homeowners often mistake for damp penetrating from outside rather than a heat loss and ventilation issue.

Converted mansion block flats with poor airflow

The mansion blocks and subdivided houses along Golders Green Road and nearby avenues often have bathrooms and kitchens with no window and undersized or blocked extractor fans. Steam and cooking moisture has nowhere to escape, settling on ceilings, tiled reveals and behind bathroom cabinets. Ground and lower ground floor flats fare worst, frequently showing mould in corners furthest from any heat source.

Loft conversions and extensions trapping moisture

Golders Green's larger family houses have commonly been extended into lofts and rear additions to suit multi-generational households. Where these conversions lack proper roof ventilation or were finished with inadequate vapour control, moisture becomes trapped within the new rooms. This shows as mould around dormer windows, sloped ceilings and junctions between old and new brickwork, often worsening through autumn and winter months.

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 Golders 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.
