Cavity wall insulation removal in County Armagh

Cavity wall insulation removal takes failed fill out of the cavity, usually by lifting bricks at low level and extracting the material with an industrial vacuum and rods, then cleaning the cavity and rebuilding the brickwork. Our County Armagh coverage includes Craigavon, Portadown, Armagh and the towns around them.

Cavity wall insulation removal across County Armagh

We cover 4 towns in County Armagh: Craigavon, Portadown, Armagh and Lurgan.

Local weather affects which walls can be filled. 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.

If your County Armagh installation has a guarantee, we check it first; the guarantee route may cover the work. Damp in an insulated County Armagh home is not always the insulation's fault, so the diagnosis comes before any extraction.

Building control in Northern Ireland

In Northern Ireland, inserting insulation into an existing cavity wall needs a building control application to your council before the work. We make sure the application route is agreed and confirmed in writing before any drilling starts.

Should I remove my cavity wall insulation?

Not always. Welsh Government guidance makes the point that extraction is not always the right remedy. Damp can come from blocked gutters, failed pointing, bridged damp-proof courses or condensation, none of which removal fixes. We start with a damp investigation and borescope checks, then recommend removal only where the fill itself is the problem.

What is included

  • Damp investigation and borescope diagnosis first
  • Brick removal and reinstatement
  • Full extraction and cavity clean
  • Camera check before rebuild
  • Waste disposal
  • Option to refill with a suitable system
