Quick answer: Damp & Mould Solutions UK removes and treats black mould at properties in Friern Barnet, and deals with the moisture driving it rather than painting over it. Mould treatment starts from £300, with a fixed price confirmed from photos or a short video before we attend. 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. If the cause of the moisture is not clear, a full damp and mould survey is a separate service, £500, or £450 when you book online and pay the deposit. Call 020 3051 8478.

Leak to dry to treated, one company in Friern Barnet

Friern Barnet's housing runs from Victorian and Edwardian terraces around Woodhouse Road and Colney Hatch to 1930s semis near Friary Park and post-war flats close to the North Circular. Solid brick walls without cavities, ageing single-glazed sash windows and older bathroom extensions all struggle to shed moisture, so mould readily takes hold on cold external walls and in poorly ventilated corners.

Areas of Friern Barnet we cover

We treat mould right across Friern Barnet and its neighbourhoods, including:

Common causes of mould in Friern Barnet homes

Solid-wall Victorian terraces around Colney Hatch and Woodhouse Road

These homes have solid brick walls with no cavity, so cold spots form wherever furniture sits against an external wall or a chimney breast has been sealed up. Black mould spreads behind wardrobes and headboards in bedrooms, and on ceilings where old lath and plaster holds dampness. We treat the mould and improve airflow so it stays gone.

1930s semis near Friary Park with dated bathrooms

Many semis around Friary Park still have original or poorly extracted bathrooms, so steam has nowhere to go and condensation mould builds on tiled walls, window reveals and ceilings above the bath. Left untreated, it spreads into adjoining bedrooms through shared walls. We remove the mould and fit proper extraction to stop steam recurring.

Ex-council flats and conversions near New Southgate and the North Circular

Flats converted from larger houses or built as post-war blocks often have restricted through-draught, single-glazed windows and shared walls that stay cold, encouraging black mould around window frames and in unheated box rooms. Traffic noise on busy roads also means windows stay shut, trapping moisture. We fix the source, not just the staining, so it does not return.

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 Friern Barnet cost?
Mould treatment starts from £300, with a fixed price confirmed from photos or a short video before we attend. If the cause of the moisture is not clear, a full damp and mould survey is a separate service, £500, or £450 when you book online and pay the deposit. 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.
