Damp investigation after cavity insulation in Eastbourne

Eastbourne homeowners, buyers, landlords and agents can book a damp investigation with the price agreed first. A damp investigation finds out why an insulated wall is showing damp or mould: rain getting in through defects, bridged or wet fill, debris in the cavity, a breached damp-proof course, or condensation.

Damp investigation after cavity insulation for Eastbourne properties

Our East Sussex coverage takes in Eastbourne (BN21) and nearby Hailsham, Seaford and Bexhill-on-Sea. It is roughly 19 miles east of Brighton.

We never cold-call in Eastbourne or anywhere else, and we do not work with doorstep claims companies. Damp in an insulated Eastbourne home is not always the insulation's fault, so the diagnosis comes before any extraction.

Every elevation is judged on its own exposure. 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.

For regulations, if cavity wall insulation follows in Eastbourne, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
