What we look for in Cwmbran

Exposure to wind-driven rain varies across Gwent: 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.
Two-tone schemes, such as a darker plinth or entrance surround, are an option on houses in Cwmbran.

Permissions in Wales
Householder rules in Wales are similar to England's: in Cwmbran, a similar-looking finish on a house is often permitted, but conservation areas, flats and listed buildings need permission or consent.
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 texture will it have?
Thin-coat renders come in grain sizes, typically 1–2mm. A 1.5mm grain is a common middle ground: fine enough to look smooth from the street, coarse enough to hide minor imperfections.
