Cavity wall insulation for flats for Dumbarton properties

If your property is in Dumbarton or the G82 district or nearby Clydebank, Bearsden and Bishopbriggs, it is within our Dunbartonshire coverage. It is around 7 miles north-west of Clydebank.

For landlords and managing agents in Dumbarton, we survey in batches and return a result sheet and fixed price per address. Blocks of flats in Dumbarton are surveyed as a whole, because the cavity runs across every flat in the building.

Every elevation is judged on its own exposure. 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.

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

Funding in Scotland

In Scotland, Home Energy Scotland is the route to the Home Energy Scotland Grant and Loan and Warmer Homes Scotland.

Fire and height

For blocks, the material must suit the building's height and use. Non-combustible mineral wool is the usual choice; we confirm the system and its certificate limits in writing.
