Cavity wall suitability survey for Newtownards properties

We cover Newtownards and the BT23 postcode district, including nearby Bangor and Downpatrick. It is about 5 miles south of Bangor.

The written result for your Newtownards property is plain English: what we found, what it means and what, if anything, to do next. Where a Newtownards wall shows cold patches or damp, the survey targets those areas first rather than sampling at random.

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.

As for paperwork, in Newtownards 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.

What the surveyor checks

Wall construction and thickness at window reveals; cavity width and debris with a borescope; brickwork, pointing, render, sills, gutters and downpipes; signs of damp inside and out; air bricks and flues; joins with neighbours and extensions; and the exposure of each elevation to wind-driven rain.
