Leak to dry to treated, one company in Harlesden
Harlesden's housing runs from Victorian and Edwardian terraces around Harlesden Green to inter-war semis near Stonebridge and converted flats along Manor Park Road and Station Road. Many terraces have been split into multiple flats with shared plumbing and limited ventilation, while solid brick walls and ageing single-glazed sash windows leave properties prone to condensation, penetrating damp and recurring mould.

Common causes of mould in Harlesden homes
Converted terraces with poor airflow
Many Harlesden terraces near Station Road and Manor Park Road have been divided into flats, often losing through-ventilation as chimneys are sealed and internal doors added. Bathrooms and kitchens without working extractor fans trap warm, moist air, which settles on cooler external walls and ceilings. This produces black mould in corners, behind wardrobes and around window reveals, particularly in ground and top-floor conversions.
Solid brick walls and cold bridging
The Victorian and Edwardian solid-wall properties common around Harlesden Green and Wrottesley Road lack a cavity, so heat escapes quickly and internal wall surfaces stay cold. Without adequate heating or insulation, moisture in the air condenses on these cold spots, especially at external corners, above skirting boards and behind furniture pushed against outside walls, leading to persistent surface mould that returns after cleaning.
Ageing roofs, gutters and window frames
Older housing stock in Harlesden, including properties near Acton Lane and the Stonebridge fringe, often has ageing roof coverings, deteriorating pointing and timber window frames prone to failed seals. Rainwater tracking through worn brickwork or leaking gutters causes penetrating damp and staining on ceilings and upper walls, creating conditions for mould growth that will keep recurring until the actual point of water entry is identified and repaired.

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.
