Gorseinon: walls, weather and approvals
We also cover Llanelli and Swansea, close to Gorseinon. Gorseinon is about 5 miles from Swansea. South Wales has long runs of solid-wall valley terraces, Victorian and Edwardian town housing and post-war council estates.
Parts of West Glamorgan fall in the higher wind-driven rain exposure bands, especially coastal and upland sites, so render specification, movement joints and detailing at cills, verges and the base of the wall matter more than usual.
For Gorseinon homeowners matching a new extension to an existing rendered house, we compare monocouche and silicone samples first.

Approvals in Wales
Householder rules in Wales are similar to England's: in Gorseinon, a similar-looking finish on a house is often permitted, but conservation areas, flats and listed buildings need permission or consent.
Building control in Wales applies to most insulation and re-rendering jobs of this size; the quote states who submits the notice.
Can monocouche go over insulation?
No — insulation systems use a mesh-reinforced base coat and a thin-coat finish instead. If you want insulation as well as a new finish, see insulated render.

Monocouche render in Gorseinon: questions
Does monocouche need painting?
No — it's through-coloured. Cleaning every few years keeps it looking fresh.
Monocouche or silicone for an extension?
Both work on new blockwork. Silicone over a base coat costs a little more but tends to stay cleaner.
Is monocouche waterproof?
It's water-resistant and sheds rain, while still allowing some vapour through.
