Cavity wall suitability survey for Barnstaple properties

Our Devon coverage takes in Barnstaple (EX31) and nearby Bideford, Tiverton and Exeter. It is roughly 34 miles north-west of Exeter.

Where a Barnstaple wall shows cold patches or damp, the survey targets those areas first rather than sampling at random. Every inspection point in Barnstaple is photographed and logged, so you have a record to show a buyer, lender or contractor.

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.

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

Rules in England

Filling a cavity is notifiable building work and needs a building notice or competent-person self-certification if insulation work follows.
