Thermal imaging survey in County Londonderry

Thermal imaging survey is available throughout County Londonderry, from Derry to Coleraine and Limavady, with the price agreed first. A thermal imaging survey uses an infrared camera to show surface temperature differences across your walls, which can reveal empty or settled insulation, cold bridges and air leaks.

Thermal imaging survey across County Londonderry

We cover 4 towns in County Londonderry: Derry, Coleraine, Limavady and Magherafelt.

Every elevation is judged on its own exposure. 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.

Every inspection point in County Londonderry is photographed and logged, so you have a record to show a buyer, lender or contractor. Buyers and sellers in County Londonderry often book this check when a survey report or EPC raises questions about the walls.

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.

What thermal images can and cannot show

They show patterns, not proof. A cooler stripe inside might be missing fill, a cold bridge at a lintel or simply a radiator switched off. That is why we pair the images with borescope checks before recommending any work.

What is included

  • Interior and exterior images
  • Annotated report
  • Borescope checks of suspect areas
  • Recommendations, if any
