Existing insulation and guarantee check for Downpatrick properties
Downpatrick sits in County Down, around 22 miles south of Bangor. We work across the BT30 district, including nearby Newtownards, Banbridge and Bangor.
Buyers and sellers in Downpatrick often book this check when a survey report or EPC raises questions about the walls. A survey in Downpatrick gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound.
Every elevation is judged on its own exposure. 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, if cavity wall insulation follows in Downpatrick, 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.
