Cavity insulation top-up for Newry properties
Newry sits in County Down, roughly 43 miles south-west of Bangor. We work across the BT34 district, including nearby Banbridge, Downpatrick and Newtownards.
Most Newry 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. If a wall in Newry 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.
Before any material is chosen, exposure is checked. Parts of County Down 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 Newry inserting cavity wall insulation needs a building control application to the council before work starts.

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.
