Cavity wall insulation for landlords for Barnstaple properties

We cover Barnstaple and the EX31 postcode district, including nearby Bideford, Tiverton and Exeter. It is about 34 miles north-west of Exeter.

For commercial buildings in Barnstaple, the survey also considers building use and fire requirements before a material is specified. Per-address photo records for Barnstaple properties make compliance files and EPC updates straightforward.

Before any material is chosen, exposure is checked. Parts of Devon face some of the heaviest wind-driven rain in the UK, especially exposed coastal and upland sites. Here the survey is stricter: some walls suit only certain certified systems, and some should not be filled at all.

On compliance, in Barnstaple filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
