Borescope cavity inspection for Derry properties
Derry is among the towns we cover in County Londonderry, alongside Limavady, Coleraine and Magherafelt. Derry is one of the main towns we cover in County Londonderry.
Buyers and sellers in Derry often book this check when a survey report or EPC raises questions about the walls. The written result for your Derry property is plain English: what we found, what it means and what, if anything, to do next.
Local weather affects which walls can be filled. 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.
In terms of approvals, if cavity wall insulation follows in Derry, inserting cavity wall insulation needs a building control application to the council before work starts.
