Homes and walls in Chelsea
As well as Chelsea itself, we quote in Battersea, Fulham and Shepherds Bush. London's housing includes a large stock of Victorian and Edwardian solid-wall terraces, inter-war semis and post-war blocks, and conservation areas cover many streets — so planning is often the first question for external work.
Much of Greater London 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 Chelsea, we'll show you what adding insulation under the silicone would cost at the same time.

Planning and building control in England
Before quoting in Chelsea, we check whether the property is in a conservation area, under an Article 4 direction or listed, because that decides whether changing the outside needs planning permission.
Insulating or re-rendering more than half of a wall's area brings in Part L of the Building Regulations, so building control is notified and the wall is upgraded to about 0.30 W/m²K where practical.
How is silicone render applied?
On masonry, the wall is prepared and any loose material removed. A base coat with glass-fibre mesh is applied over the whole wall to resist cracking, followed by a primer and the silicone finish, trowelled to its grain size. On EWI, the same base coat, primer and finish go over the insulation boards.

Silicone render in Chelsea: 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.
Can I paint silicone render later?
Yes, with a compatible silicone paint, though through-coloured render rarely needs it.
Do you cover Chelsea?
Yes — we survey and quote silicone render in Chelsea (SW3) and nearby Battersea, Fulham and Shepherds Bush, with a fixed written price before any work starts.
