Existing insulation and guarantee check for Coleraine properties
If your property is in Coleraine or the BT52 district or nearby Limavady, Magherafelt and Derry, it is within our County Londonderry coverage. It is around 27 miles east of Derry.
A survey in Coleraine gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound. Every inspection point in Coleraine 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 Londonderry 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.
For regulations, if cavity wall insulation follows in Coleraine, 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.
