Before we quote in Welshpool
We also cover Newtown and Rhosllanerchrugog, close to Welshpool. It's roughly 12 miles from Welshpool to Newtown, the largest town in Powys. Mid Wales is largely rural, with stone farmhouses, cottages and market-town terraces, many of them solid-walled.
Parts of Powys 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.
Silicone suits most rendering jobs in Welshpool, either on its own or over insulation.

Planning and building control in Wales
Householder rules in Wales are similar to England's: in Welshpool, 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.
Is silicone render maintenance-free?
Not quite. It stays cleaner than most renders because water runs off and dries quickly, but north-facing or tree-shaded walls can still gather algae. A gentle biocide wash every few years keeps it looking new. Pressure washing is avoided because it can damage the surface.

Silicone render in Welshpool: questions
How long does silicone render take to dry?
It's touch-dry within hours but needs dry weather above about 5°C for the first day or two to cure properly.
Can silicone render go over old render?
If the old render is sound and well bonded, often yes after cleaning and priming. Hollow or cracked areas are cut out and repaired first.
Does silicone render crack?
The mesh-reinforced base coat and the render's flexibility make cracking much less likely than with sand and cement, but structural movement in the wall can still show through.
