Damp investigation after cavity insulation across County Down
We cover 5 towns in County Down: Bangor, Newtownards, Newry, Downpatrick and Banbridge.
Every elevation is judged on its own exposure. Parts of County Down 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.
Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for County Down properties, so you can choose who fixes them. Where a County Down wall does need work, bricks are lifted and rebuilt in matching mortar, and the cavity is checked with a camera before it is closed up.
Building control in Northern Ireland
In Northern Ireland, inserting insulation into an existing cavity wall needs a building control application to your council before the work. We make sure the application route is agreed and confirmed in writing before any drilling starts.
