Repointing and pre-insulation repairs in Cardiff

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. In Cardiff the visit is priced up front, and any follow-on work is quoted separately so you can choose.

Repointing and pre-insulation repairs for Cardiff properties

Cardiff is among the towns we cover in South Glamorgan, alongside Penarth and Barry. Cardiff is one of the main towns we cover in South Glamorgan.

Damp in an insulated Cardiff home is not always the insulation's fault, so the diagnosis comes before any extraction. Where a Cardiff 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.

Wind-driven rain is the first thing the surveyor weighs up. 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 Cardiff, 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.
