Existing insulation and guarantee check for Bangor, County Down properties

Bangor sits in County Down. We work across the BT20 district, including nearby Newtownards and Downpatrick.

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

Exposure matters for every cavity wall. 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 Bangor, 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.
