Cavity wall suitability survey for Merthyr Tydfil properties
Merthyr Tydfil sits in Mid Glamorgan, around 19 miles north-east of Bridgend. We work across the CF47 district, including nearby Aberdare, Rhondda and Tonypandy.
The written result for your Merthyr Tydfil property is plain English: what we found, what it means and what, if anything, to do next. 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.
For regulations, 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.
