Existing insulation and guarantee check for Swansea properties
We cover Swansea and the SA1 postcode district, including nearby Briton Ferry, Gorseinon and Neath. Swansea is one of the main towns we cover in West Glamorgan.
The written result for your Swansea property is plain English: what we found, what it means and what, if anything, to do next. Where a Swansea 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 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 the rules side, if cavity wall insulation follows 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.

How to tell if a house already has cavity insulation
Look for a regular pattern of small patched holes in the mortar joints, often about a metre apart. Check the EPC, which may say 'filled cavity'. Ask the seller for a guarantee. The reliable answer is a borescope check, because patched holes can be from a fill that was later removed and EPCs are sometimes wrong.
