Damp investigation after cavity insulation for Crowborough properties
Our East Sussex coverage takes in Crowborough (TN6) and nearby Hailsham, Bexhill-on-Sea and Rottingdean. It is roughly 20 miles north-east of Brighton.
Damp in an insulated Crowborough home is not always the insulation's fault, so the diagnosis comes before any extraction. We never cold-call in Crowborough or anywhere else, and we do not work with doorstep claims companies.
Wind-driven rain is the first thing the surveyor weighs up. East Sussex has a mix of moderate and more exposed sites. Hilltop, coastal and west-facing walls take the brunt of wind-driven rain, so the survey records exposure for each elevation before a material is chosen.
As for paperwork, if cavity wall insulation follows in Crowborough, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Common causes we check
Defective pointing, cracked render and porous bricks letting rain in; leaking gutters and downpipes; fill bridging the cavity where mortar droppings or debris have collected; ground levels above the damp-proof course; and condensation from cooking, drying clothes and too little ventilation.
