Cavity insulation top-up for Newtownabbey properties
Newtownabbey is among the towns we cover in County Antrim, alongside Belfast, Carrickfergus and Lisburn. It is around 4 miles north of Belfast.
Where a Newtownabbey property has an extension or a conservatory, we check how the old and new walls meet, because that junction is often missed. Newtownabbey 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.
On compliance, in Newtownabbey inserting cavity wall insulation needs a building control application to the council before work starts.

How do I know if my walls need a top-up?
Cold patches on internal walls, a thermal image showing uneven heat loss, or an EPC that says 'filled cavity' when parts of the house feel colder are all signs. Extensions are a common cause: the new wall is insulated as built, but the old wall it joins may have been left partly empty.
