Thermal imaging survey for Merthyr Tydfil properties
Merthyr Tydfil is among the towns we cover in Mid Glamorgan, alongside Aberdare, Rhondda and Tonypandy. It is about 19 miles north-east of Bridgend.
Buyers and sellers in Merthyr Tydfil often book this check when a survey report or EPC raises questions about the walls. Where a Merthyr Tydfil wall shows cold patches or damp, the survey targets those areas first rather than sampling at random.
Wind-driven rain is the first thing the surveyor weighs up. Parts of Mid Glamorgan 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 Merthyr Tydfil, 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.
