Cavity insulation for new builds and extensions for Newry properties
Newry is among the towns we cover in County Down, alongside Banbridge, Downpatrick and Newtownards. It is about 43 miles south-west of Bangor.
Where a Newry property has an extension or a conservatory, we check how the old and new walls meet, because that junction is often missed. If a wall in Newry is not suitable, for example because of an undiagnosed damp patch or a very exposed gable, you are told so in writing with the reason.
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.
In terms of approvals, in Newry inserting cavity wall insulation needs a building control application to the council before work starts.

Extensions that join an older house
Where an extension meets an existing cavity wall, the junction is a weak point. We can borescope and fill the existing wall at the same time so the old and new walls perform together.
