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.

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.
What our customers say
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.
