Cavity insulation for new builds and extensions for Clydebank properties

Clydebank is among the towns we cover in Dunbartonshire, alongside Bearsden, Bishopbriggs and Dumbarton. Clydebank is one of the main towns we cover in Dunbartonshire.

Where a Clydebank property has an extension or a conservatory, we check how the old and new walls meet, because that junction is often missed. A suitable wall in Clydebank is usually filled in a single day from outside, with drill holes made good to match the pointing.

Wind-driven rain is the first thing the surveyor weighs up. Parts of Dunbartonshire 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.

For regulations, in Clydebank no building warrant is needed for insulation within a wall, but the work must meet the building standards.

What we work from

Your architect's or designer's specification and the energy calculation for the job. We match the product, thickness and fixing to that spec, keep cavities clean as the walls rise, and fit cavity trays, closers and stop ends where shown so the building control inspection goes smoothly.
