Local considerations in Barnes
As well as Barnes itself, we quote in Chiswick, Putney and Fulham. 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 Barnes, we'll show you what adding insulation under the silicone would cost at the same time.

Permissions in England
Before quoting in Barnes, 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.
Building control applies once more than half of a wall is insulated or re-rendered, or more than a quarter of the whole building envelope, and your written quote says how that's handled.
Silicone or monocouche?
Monocouche is a thicker single-coat cement render used mainly on new blockwork. Silicone is thinner, more flexible and usually more resistant to staining, and it's the finish used over insulation. On older or mixed walls, silicone over a mesh-reinforced base coat is generally the safer choice.

Silicone render in Barnes: 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.
