Existing insulation and guarantee check for Newtownards properties

Our County Down coverage takes in Newtownards (BT23) and nearby Bangor and Downpatrick. It is around 5 miles south of Bangor.

A survey in Newtownards gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound. The written result for your Newtownards property is plain English: what we found, what it means and what, if anything, to do next.

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 the rules side, if cavity wall insulation follows in Newtownards, inserting cavity wall insulation needs a building control application to the council before work starts.

How to tell if a house already has cavity insulation

Look for a regular pattern of small patched holes in the mortar joints, often about a metre apart. Check the EPC, which may say 'filled cavity'. Ask the seller for a guarantee. The reliable answer is a borescope check, because patched holes can be from a fill that was later removed and EPCs are sometimes wrong.
