Party wall cavity insulation for Craigavon properties
Our County Armagh coverage takes in Craigavon (BT65) and nearby Lurgan, Portadown and Armagh. Craigavon is one of the main towns we cover in County Armagh.
If a wall in Craigavon 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. Most Craigavon 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.
Exposure matters for every cavity wall. Parts of County Armagh 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.
In terms of approvals, in Craigavon inserting cavity wall insulation needs a building control application to the council before work starts.

What we need from you and your neighbour
The cavity is shared, so we talk you through notifying your neighbour before work. Filling is done from your side, usually through the loft. The survey confirms the wall is a cavity wall and not solid masonry, and checks for cables, flues and any gaps that would let fill escape.
What is included in Craigavon
- Loft inspection and borescope check
- Written result and photos
