Before we quote in Oxfordshire
Homes across the South East range from inter-war semis and post-war estates, which are mostly cavity-walled, to older solid-walled cottages and Victorian town terraces.
Much of Oxfordshire sits in the lower wind-driven rain exposure bands, which keeps the choice of finishes wide — though hilltop, coastal and exposed gable walls can still need a tougher specification, so we check the actual site.
If you're re-rendering in Oxfordshire, we'll show you what adding insulation under the silicone would cost at the same time.

Approvals in England
For houses, external wall insulation and render are often permitted development where the finish looks similar to the existing walls. Planning permission is usually needed in conservation areas, National Parks, National Landscapes, the Broads and World Heritage Sites (where cladding a house in stone, artificial stone, pebble dash, render, timber, plastic or tiles isn't permitted development), for flats and maisonettes, for commercial buildings, under an Article 4 direction, or where the look changes noticeably. Listed buildings need listed building consent.
Renovating more than half of a wall's area — insulating it, or stripping and re-rendering it — or more than a quarter of the building's whole external envelope brings in the energy requirements of Part L, so building control needs to be involved and the wall should reach about 0.30 W/m²K where that's technically, functionally and economically feasible.
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 Oxfordshire: questions
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.
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.
Do you cover all of Oxfordshire?
Yes. We survey and quote silicone render across Oxfordshire, including Oxford, Banbury, Abingdon, Bicester, Didcot.
Do I need planning permission in England?
