Cavity insulation for new builds and extensions for Newtownards properties
If your property is in Newtownards or the BT23 district or nearby Bangor and Downpatrick, it is within our County Down coverage. It is about 5 miles south of Bangor.
Most Newtownards houses built from the 1920s onwards have cavity walls, but the survey still checks each one: cavity width, debris, the condition of the brickwork and how exposed each wall is. Newtownards properties with rendered or painted walls get a closer look at the outer finish, because cracked render can let rain behind it.
Exposure matters for every cavity wall. 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.
On the rules side, in Newtownards 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.
