Cavity wall suitability survey for Swansea properties
If your property is in Swansea or the SA1 district or nearby Briton Ferry, Gorseinon and Neath, it is within our West Glamorgan coverage. Swansea is one of the main towns we cover in West Glamorgan.
Buyers and sellers in Swansea often book this check when a survey report or EPC raises questions about the walls. The written result for your Swansea 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 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.
On compliance, in Swansea filling a cavity is notifiable work under the Building Regulations as they apply in Wales, usually self-certified through a competent person scheme.

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.
