Cavity wall work in Dunoon

If your property is in Dunoon or the PA23 district or nearby Helensburgh and Oban, it is within our Argyll and Bute coverage. It is around 8 miles south-west of Helensburgh.

Local weather affects which walls can be filled. 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.

On compliance, in Dunoon no building warrant is needed for insulation within a wall, but the work must meet the building standards.
