Cavity wall suitability survey for Downpatrick properties

Our County Down coverage takes in Downpatrick (BT30) and nearby Newtownards, Banbridge and Bangor. It is roughly 22 miles south of Bangor.

Where a Downpatrick wall shows cold patches or damp, the survey targets those areas first rather than sampling at random. Buyers and sellers in Downpatrick often book this check when a survey report or EPC raises questions about the walls.

Wind-driven rain is the first thing the surveyor weighs up. 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.

On compliance, in Downpatrick 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.
