Existing insulation and guarantee check for Cardiff properties
If your property is in Cardiff or the CF10 district or nearby Penarth and Barry, it is within our South Glamorgan coverage. Cardiff is one of the main towns we cover in South Glamorgan.
Every inspection point in Cardiff is photographed and logged, so you have a record to show a buyer, lender or contractor. A survey in Cardiff gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound.
Every elevation is judged on its own exposure. Parts of South 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 Cardiff, 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.
