Damp, mould & leak services in Hendon
Hendon's housing stock spans Edwardian and interwar semi-detached houses, 1960s and 1970s purpose-built flats, and post-war council terraces. This mix of cavity and solid-wall construction, combined with older rooflines and ageing drainage infrastructure, creates persistent conditions for rising damp, penetrating damp, and condensation-related mould growth throughout the area.

Common damp problems in Hendon homes
Interwar Semi-Detached Houses and Rising Damp
Many of Hendon's interwar semi-detached properties on roads such as those around Holders Hill and Temple Fortune were built with shallow or rudimentary damp-proof courses that have long since deteriorated. Ground levels raised over decades by successive landscaping can bridge these courses entirely, allowing moisture to travel steadily up through brick and plaster, producing stained skirting boards, peeling decorations, and a persistent musty odour at ground-floor level.
Flat-Roof Leaks in 1960s and 1970s Blocks
West Hendon and Colindale contain a significant number of purpose-built flat-roof residential blocks constructed during the post-war decades. Felt and asphalt flat roofs of this era have a finite lifespan and are particularly vulnerable to ponding water and UV degradation. When membranes crack or joints open, water tracks silently through roof structures and appears as ceiling staining, blistered plaster, or mould patches in top-floor flats, often well away from the original point of entry.
Condensation Mould in Converted Victorian and Edwardian Terraces
Sections of Cricklewood and Child's Hill bordering Hendon contain older Victorian and Edwardian terraced housing frequently subdivided into flats. Inadequate ventilation in bathrooms and kitchens, combined with solid brick walls that retain cold surface temperatures, makes these conversions highly susceptible to condensation mould. Black mould growth commonly appears on north-facing walls, in window reveals, and inside built-in wardrobes where air circulation is poorest.
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.
