Cavity insulation for new builds and extensions for Cumbernauld properties

Cumbernauld is among the towns we cover in Lanarkshire, alongside Airdrie, Coatbridge and Motherwell. It is around 12 miles north of Hamilton.

Most Cumbernauld houses built from the 1920s onwards have cavity walls, but the survey still checks each one: cavity width, debris, the condition of the brickwork and how exposed each wall is. Where a Cumbernauld property has an extension or a conservatory, we check how the old and new walls meet, because that junction is often missed.

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