Cavity wall suitability survey across West Glamorgan
We cover 4 towns in West Glamorgan: Swansea, Neath, Briton Ferry and Gorseinon.
Exposure matters for every cavity wall. Parts of West 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.
Buyers and sellers in West Glamorgan often book this check when a survey report or EPC raises questions about the walls. A survey in West Glamorgan gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound.
Building Regulations in Wales
In Wales, filling an existing cavity is also notifiable building work under the Building Regulations as they apply in Wales. A registered installer normally self-certifies it through a competent person scheme; otherwise a building notice goes to your council's building control before work starts. Welsh rules can differ from England's, so the notification route is confirmed in writing on your quote.

What the surveyor checks
Wall construction and thickness at window reveals; cavity width and debris with a borescope; brickwork, pointing, render, sills, gutters and downpipes; signs of damp inside and out; air bricks and flues; joins with neighbours and extensions; and the exposure of each elevation to wind-driven rain.
