Cavity insulation for new builds and extensions for Newtownabbey properties
Newtownabbey is among the towns we cover in County Antrim, alongside Belfast, Carrickfergus and Lisburn. It is about 4 miles north of Belfast.
If a wall in Newtownabbey 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. Newtownabbey properties with rendered or painted walls get a closer look at the outer finish, because cracked render can let rain behind it.
Before any material is chosen, exposure is checked. 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.
As for paperwork, in Newtownabbey 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.
