Cardiff: walls, weather and approvals
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.
Lime work in Cardiff is scheduled for frost-free months so the render cures properly.

Planning and building control in Wales
For homes in Cardiff, the local planning authority decides any borderline cases; changing a brick house to render, or work on flats, usually needs an application in Wales.
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.
Why use lime instead of cement?
Cement render is hard and relatively impermeable. On older walls built with lime mortar, it can crack, let rain in at the cracks and then stop the wall drying, leading to damp patches inside and spalling stone or brick. Lime is softer, more flexible and vapour-open, so moisture can escape.

Lime render in Cardiff: questions
Can lime render be applied in winter?
Only with protection and in frost-free conditions. Spring to early autumn is the usual season.
Is lime render more expensive?
Usually, because it's applied in coats by hand and needs more curing time.
Should I remove cement render from my stone house?
If it's cracked, hollow or trapping damp, often yes. If it's sound and the wall is dry, it may be left. The survey looks at both.
Do you cover Cardiff?
Yes — we survey and quote lime render in Cardiff (CF10) and nearby Penarth, Caerphilly and Barry, with a fixed written price before any work starts.
