Cavity insulation for new builds and extensions for Campbeltown properties

Campbeltown sits in Argyll and Bute. We work across the PA28 district.

A suitable wall in Campbeltown is usually filled in a single day from outside, with drill holes made good to match the pointing. For semi-detached and terraced homes in Campbeltown, cavity barriers are fitted where your wall meets your neighbour's so the fill stays on your side.

Exposure matters for every cavity wall. Parts of Argyll and Bute 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 Campbeltown no building warrant is needed for insulation within a wall, but the work must meet the building standards.

Extensions that join an older house

Where an extension meets an existing cavity wall, the junction is a weak point. We can borescope and fill the existing wall at the same time so the old and new walls perform together.
