Cavity wall suitability survey for Carrickfergus properties
Carrickfergus is among the towns we cover in County Antrim, alongside Newtownabbey, Larne and Belfast. It is roughly 9 miles north-east of Belfast.
The written result for your Carrickfergus property is plain English: what we found, what it means and what, if anything, to do next. Buyers and sellers in Carrickfergus often book this check when a survey report or EPC raises questions about the walls.
Local weather affects which walls can be filled. 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 the rules side, in Carrickfergus inserting cavity wall insulation needs a building control application to the council before work starts.
Rules in Northern Ireland
Inserting cavity wall insulation needs a building control application to the council before work starts if insulation work follows.

Wall construction and thickness at window reveals; cavity width and debris with a borescope; brickwork, pointing, render, sills, gutters and downpipes; signs of damp inside and out; air bricks and flues; joins with neighbours and extensions; and the exposure of each elevation to wind-driven rain.
