Damp, mould & leak services in Angel
Angel's housing stock is dominated by Georgian and Victorian terraces, mid-century council blocks, and converted warehouse units around the former industrial corridors near City Road. This mix of ages and construction methods creates persistent challenges with damp and moisture, as older solid-wall properties lack cavity insulation and many conversions have inadequate ventilation systems.

Common damp problems in Angel homes
Rising Damp in Georgian and Victorian Terraces
The Georgian and early Victorian terraces throughout Barnsbury and Colbrooke Row were built without damp-proof courses, or with rudimentary lime-based barriers that have long since deteriorated. Ground-floor rooms frequently show tide marks, peeling skirting boards and efflorescence on internal walls, all indicators that moisture is travelling upward through the original stock brick construction.
Penetrating Damp in Converted Warehouse and Commercial Units
Former industrial and warehouse buildings along City Road and the fringes of Clerkenwell have been converted into flats and studios, often retaining original single-skin brick facades. These walls offer little resistance to wind-driven rain, allowing water to penetrate directly into habitable spaces. Poorly repointed mortar joints and inadequate external sealing around steel window frames are common entry points identified during surveys.
Condensation and Hidden Leaks in Council-Era Blocks
Mid-twentieth century council blocks in Pentonville and along the Caledonian Road corridor were built with flat or shallow-pitched roofs and enclosed communal duct systems that are now ageing. Poor thermal performance in these concrete-frame buildings encourages heavy condensation on cold surfaces, while shared plumbing stacks and buried horizontal runs frequently develop slow leaks that go undetected within floor and ceiling voids for extended periods.
What our customers say
Service was excellent! Explained the whole process thoroughly, arrived on time when carrying out the survey. The survey was detailed and exactly what I needed for my insurance. They returned to carry out the treatment the following week. 10/10 would highly recommend.

Patryk Gutowski, via Google
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.
