Repointing and pre-insulation repairs in South Glamorgan

Pre-insulation repairs put right the defects that let rain into a wall, so it can be filled safely: failed pointing, spalled bricks, cracked sills and render, and leaking gutters and downpipes. Our South Glamorgan coverage includes Cardiff, Barry, Penarth and the towns around them.

Repointing and pre-insulation repairs across South Glamorgan

We cover 3 towns in South Glamorgan: Cardiff, Barry and Penarth.

Before any material is chosen, exposure is checked. 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.

Where a South Glamorgan wall does need work, bricks are lifted and rebuilt in matching mortar, and the cavity is checked with a camera before it is closed up. Damp in an insulated South Glamorgan home is not always the insulation's fault, so the diagnosis comes before any extraction.

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.

Why repairs come first

Energy Saving Trust advice is to fix brickwork, pointing, roofs, gutters and downpipes before filling. A filled cavity is less forgiving of a wet outer leaf than an empty one, so we price repairs separately and you choose who carries them out.
