Before we quote in Archway
We cover Archway and nearby Holloway, Muswell Hill and Chalk Farm. 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 Archway, 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 Archway, 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.
If the work covers more than half of a wall, or a quarter of the building's whole envelope, it counts as renovating a thermal element, with a target of about 0.30 W/m²K where feasible.
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 Archway: questions
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.
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.
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 Archway?
Yes — we survey and quote silicone render in Archway (N19) and nearby Holloway, Muswell Hill and Chalk Farm, with a fixed written price before any work starts.
