Borescope cavity inspection for Coleraine properties
Coleraine is among the towns we cover in County Londonderry, alongside Limavady, Magherafelt and Derry. It is roughly 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. Where a Coleraine wall shows cold patches or damp, the survey targets those areas first rather than sampling at random.
Wind-driven rain is the first thing the surveyor weighs up. 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.
On the rules side, if cavity wall insulation follows in Coleraine, inserting cavity wall insulation needs a building control application to the council before work starts.

How many holes?
Enough to be representative: typically several per elevation, plus targeted checks below windows, at corners and near any damp patches. Each one is photographed and logged.
