Damp, mould & leak services in Caterham
Caterham's housing stock spans Victorian and Edwardian terraces in the Valley, through interwar semis on the Hill, to postwar estates and modern infill developments. This mix of solid chalk geology, elevated position and older construction methods creates persistent challenges with rising damp, condensation and roof-related water ingress across the town.

Common damp problems in Caterham homes
Rising Damp in Victorian Valley Terraces
The older terraced streets of Caterham Valley, many built before damp-proof courses were standard, frequently suffer rising damp that wicks moisture up through solid brick walls. Chalk subsoil beneath these properties retains groundwater and the narrow plots limit airflow around external walls, accelerating deterioration of internal plaster and skirting boards.
Condensation and Mould in Interwar Semis on the Hill
The large stock of 1930s semi-detached properties across Caterham-on-the-Hill tends to have cavity walls that were never insulated, creating cold internal surfaces prone to condensation. Combined with the elevated exposure to wind and rain on the North Downs ridge, residents often report persistent black mould around window reveals, bathroom ceilings and chimney breast walls.
Penetrating Damp from Roof and Flashing Failures
Properties in Woldingham, Marden Park and the more rural fringes of Caterham often feature complex rooflines with valleys, dormers and multiple chimney stacks. Failed lead flashing, cracked pointing and blocked gutters on these exposed hillside homes allow rainwater to track through roof structures undetected for months, causing significant hidden timber decay and saturated ceiling plasterwork.
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.

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.
