Existing insulation and guarantee check for Ballymena properties

We cover Ballymena and the BT42 postcode district, including nearby Antrim, Larne and Newtownabbey. It is roughly 23 miles north-west of Belfast.

Where a Ballymena wall shows cold patches or damp, the survey targets those areas first rather than sampling at random. Every inspection point in Ballymena is photographed and logged, so you have a record to show a buyer, lender or contractor.

Exposure matters for every cavity wall. Parts of County Antrim 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, if cavity wall insulation follows in Ballymena, 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.
