Cavity insulation top-up for Craigavon properties
If your property is in Craigavon or the BT65 district or nearby Lurgan, Portadown and Armagh, it is within our County Armagh coverage. Craigavon is one of the main towns we cover in County Armagh.
A suitable wall in Craigavon is usually filled in a single day from outside, with drill holes made good to match the pointing. For semi-detached and terraced homes in Craigavon, cavity barriers are fitted where your wall meets your neighbour's so the fill stays on your side.
Before any material is chosen, exposure is checked. 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.
For regulations, in Craigavon inserting cavity wall insulation needs a building control application to the council before work starts.
Funding in Northern Ireland
In Northern Ireland, the Affordable Warmth Scheme helps eligible households with a gross income under £23,000.

When a top-up is not enough
If the existing fill is wet, contaminated with debris or breaking down, adding more on top can make things worse. In that case we tell you the honest option, which may be partial or full removal and refill.
