Cavity insulation for new builds and extensions for Carrickfergus properties
Our County Antrim coverage takes in Carrickfergus (BT38) and nearby Newtownabbey, Larne and Belfast. It is about 9 miles north-east of Belfast.
Most Carrickfergus 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. Carrickfergus 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 Antrim 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.
For regulations, in Carrickfergus inserting cavity wall insulation needs a building control application to the council before work starts.

What we work from
Your architect's or designer's specification and the energy calculation for the job. We match the product, thickness and fixing to that spec, keep cavities clean as the walls rise, and fit cavity trays, closers and stop ends where shown so the building control inspection goes smoothly.
