Cavity insulation for new builds and extensions for Ayr properties

If your property is in Ayr or the KA8 district or nearby Irvine and Kilmarnock, it is within our Ayrshire coverage. It is roughly 12 miles south-west of Kilmarnock.

A suitable wall in Ayr 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 Ayr, cavity barriers are fitted where your wall meets your neighbour's so the fill stays on your side.

Local weather affects which walls can be filled. Parts of Ayrshire 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 Ayr no building warrant is needed for insulation within a wall, but the work must meet the building standards.

Funding in Scotland

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.
