Existing insulation and guarantee check for Barnstaple properties

Barnstaple sits in Devon, roughly 34 miles north-west of Exeter. We work across the EX31 district, including nearby Bideford, Tiverton and Exeter.

Where a Barnstaple wall shows cold patches or damp, the survey targets those areas first rather than sampling at random. A survey in Barnstaple gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound.

Every elevation is judged on its own exposure. 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.

In terms of approvals, if cavity wall insulation follows 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.

Tracing a guarantee

Many cavity fills carry a 25-year guarantee from the Cavity Insulation Guarantee Agency (CIGA). CIGA can confirm whether a property is covered and can issue a duplicate guarantee for a fee; at the time of writing that fee is £60 including VAT, and proof of ownership is required.
