Thermal imaging survey in Derry

For properties in Derry, a thermal imaging survey starts with a clear price and ends with a written record of what was found and done. 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 for Derry properties

Derry sits in County Londonderry. We work across the BT48 district, including nearby Limavady, Coleraine and Magherafelt.

Buyers and sellers in Derry often book this check when a survey report or EPC raises questions about the walls. Where a Derry wall shows cold patches or damp, the survey targets those areas first rather than sampling at random.

Before any material is chosen, exposure is checked. 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 compliance, if cavity wall insulation follows in Derry, inserting cavity wall insulation needs a building control application to the council before work starts.
