Thermal imaging survey in Holyhead

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. In Holyhead the visit is priced up front, and any follow-on work is quoted separately so you can choose.

Thermal imaging survey for Holyhead properties

We cover Holyhead and the LL65 postcode district, including nearby Caernarfon and Bangor. It is around 20 miles west of Bangor.

Every inspection point in Holyhead is photographed and logged, so you have a record to show a buyer, lender or contractor. The written result for your Holyhead property is plain English: what we found, what it means and what, if anything, to do next.

Every elevation is judged on its own exposure. Parts of Gwynedd 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 Holyhead, filling a cavity is notifiable work under the Building Regulations as they apply in Wales, usually self-certified through a competent person scheme.

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.
