Local considerations in Cardiff
We cover Cardiff and nearby Penarth, Caerphilly and Barry. South Wales has long runs of solid-wall valley terraces, Victorian and Edwardian town housing and post-war council estates.
Exposure to wind-driven rain varies across South Glamorgan: sheltered town streets fare better than walls on high ground or facing the prevailing weather, and the render, beads and cill details are chosen with that in mind.
For Cardiff re-render jobs, we check whether building control needs notifying for your wall area.

Approvals in Wales
We check Cardiff addresses for conservation areas and listing before quoting, because Welsh permitted development rules don't cover every external change.
In Wales, insulating or re-rendering more than half of a wall's area is treated as renovating a thermal element under Approved Document L (Wales), so building control is involved before work starts.
Which new render should I choose?
On older solid walls, breathable lime or a mineral system is often safest. On sound modern masonry, silicone over a mesh base coat gives a durable, low-maintenance finish. If insulation is added, the finish is the one specified for the EWI system.

Re-rendering in Cardiff: questions
How do I know if my render has failed?
Signs include cracks, hollow sound when tapped, bulging, pieces falling off, and damp patches inside behind cracked areas.
Is it worth adding insulation?
On solid or concrete walls it's usually the most cost-effective time to do it, because access and preparation are already paid for.
Can I re-render just one wall?
Yes, though matching colour and texture to the other walls may mean recoating them too.
Do you cover Cardiff?
Yes — we survey and quote re-rendering in Cardiff (CF10) and nearby Penarth, Caerphilly and Barry, with a fixed written price before any work starts.
