Common Damp Problems in Dulwich
Rising damp is prevalent in the older Victorian housing stock across SE21 and SE22, where original damp proof courses have deteriorated or were never present in the earliest constructions. Cellar and basement damp (both rising and penetrating) is extremely common given the large number of properties with below-ground spaces. Penetrating damp through ageing render on extensions and rear elevations is another frequent finding, as render applied decades ago cracks and allows water to track through to internal walls.
Urgent cases are prioritised when water is coming through a ceiling or a pipe has burst.

We provide reports suitable as supporting evidence for housing, landlord or compliance matters investigation and remediation reports for landlords and housing associations across our coverage area.

Water Infrastructure in Dulwich Services
Dulwich Services is served by Thames Water for both water supply and sewerage. When Thames Water mains pipes fail (particularly the Victorian-era cast iron infrastructure common across South and East London), the resulting ground saturation can cause significant water ingress into nearby properties. If you have experienced unexplained damp following a Thames Water mains burst or repair in your area, our independent investigation reports establish the connection between the infrastructure event and damage to your property, supporting both Thames Water claims and buildings insurance claims.
