Borescope cavity inspection in County Down

Borescope cavity inspection is available throughout County Down, from Bangor to Newtownards and Newry, with the price agreed first. A borescope inspection pushes a small camera through a hole about the size of a pencil into the cavity to see whether it is empty, partly filled or filled, what the fill is and whether there is debris.

Borescope cavity inspection across County Down

We cover 5 towns in County Down: Bangor, Newtownards, Newry, Downpatrick and Banbridge.

Before any material is chosen, exposure is checked. 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.

Buyers and sellers in County Down often book this check when a survey report or EPC raises questions about the walls. The written result for your County Down property is plain English: what we found, what it means and what, if anything, to do next.

Building control in Northern Ireland

In Northern Ireland, inserting insulation into an existing cavity wall needs a building control application to your council before the work. We make sure the application route is agreed and confirmed in writing before any drilling starts.

When a borescope check helps

Before filling, to confirm the cavity is empty and clean. Before buying a house, to see if the EPC's claim of 'filled cavity' is true. When damp has appeared and you need to know whether the fill is wet or bridged. Before a top-up, to map which panels are empty.
