Loft insulation for Seaham properties

We cover Seaham and the SR7 postcode district, including nearby Peterlee, Chester-le-Street and Durham. It is around 10 miles north-east of Durham.

Where a Seaham home also has empty cavity walls, we can survey those at the same time. In Seaham homes this is often done on the same visit as a cavity fill, which saves a second trip.

As for paperwork, if cavity wall insulation follows in Seaham, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
