Damp, mould & leak services in Sevenoaks
Sevenoaks contains a broad mix of Victorian and Edwardian terraces, interwar semi-detached homes, post-war council-built stock and substantial detached properties on the greenbelt fringes. Older solid-wall construction across Bat and Ball and the town centre lacks cavity insulation, making penetrating damp and condensation particularly common, while sandstone and clay soils around the Greensand Ridge contribute to ground moisture issues.

Common damp problems in Sevenoaks homes
Penetrating Damp in Victorian and Edwardian Terraces
The concentration of solid-brick Victorian and Edwardian terraces around Bat and Ball and Sevenoaks town centre means external walls have no cavity to interrupt water ingress. Prolonged rainfall, which is channelled by the North Downs topography, saturates exposed brickwork and mortar joints, allowing moisture to track straight through to internal plasterwork, producing damp patches and staining that worsen each winter.
Condensation Mould in Post-War and Council-Built Properties
Post-war housing estates across Dunton Green and Riverhead were built with minimal ventilation provision and lightweight construction methods that perform poorly thermally. Cold bridging at wall junctions and around steel window frames creates persistent surface condensation, particularly in bathrooms and bedrooms. Without adequate extract ventilation, black mould colonies become established on walls and ceiling corners, posing ongoing health and structural concerns.
Hidden Roof and Chimney Leaks in Rural Greenbelt Homes
Detached and semi-detached properties in villages such as Otford, Shoreham and Kemsing frequently feature aged clay tile roofs, redundant or active chimneys and lead flashing that has lifted or cracked over decades. Water entering through these points can travel considerable distances within roof voids and wall cavities before becoming visible internally, meaning significant timber damage and saturated insulation often develop long before a homeowner notices any obvious leak.

Jensen B, via Google
I recently used a damp and mould specialist company and was extremely impressed with the service from start to finish. From the initial survey, they were knowledgeable, thorough, and took the time to clearly explain the cause of the issue rather than just treating the symptoms.
