Repointing and pre-insulation repairs in Merthyr Tydfil

Repointing and pre-insulation repairs for Merthyr Tydfil properties

Merthyr Tydfil is among the towns we cover in Mid Glamorgan, alongside Aberdare, Rhondda and Tonypandy. It is around 19 miles north-east of Bridgend.

If your Merthyr Tydfil installation has a guarantee, we check it first; the guarantee route may cover the work. Damp in an insulated Merthyr Tydfil home is not always the insulation's fault, so the diagnosis comes before any extraction.

Exposure matters for every cavity wall. Parts of Mid 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 Merthyr Tydfil, 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.
