Repointing and pre-insulation repairs for Penarth properties

Our South Glamorgan coverage takes in Penarth (CF64) and nearby Cardiff and Barry. It is about 3 miles south of Cardiff.

Where a Penarth 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. If your Penarth installation has a guarantee, we check it first; the guarantee route may cover the work.

Exposure matters for every cavity wall. 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.

As for paperwork, if cavity wall insulation follows in Penarth, filling a cavity is notifiable work under the Building Regulations as they apply in Wales, usually self-certified through a competent person scheme.

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.
