Homes and walls 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.
If you're comparing quotes in Cardiff, the written specification makes it easier to compare like for like.

Permissions 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.
What happens during the survey?
We measure each elevation, photograph the details that affect the job, check the wall construction and look for damp, cracking and loose render. Ground levels and the damp-proof course are recorded so the system starts in the right place. Eaves depth, window cills, flues, meters, soil pipes, satellite dishes and lights are all noted because each one needs a detail.
