Before we quote in Purley
We also cover Coulsdon and South Croydon, close to Purley. 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.
On tree-shaded or north-facing walls in Purley, silicone's water repellence helps it stay cleaner for longer.

Approvals in England
For a house in Purley, external insulation or render is often permitted development if it looks similar to the existing walls; conservation areas, flats, commercial buildings and listed buildings need permission or consent, so we check your address first.
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.
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 Purley: 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.
Can I paint silicone render later?
Yes, with a compatible silicone paint, though through-coloured render rarely needs it.
Do you cover Purley?
Yes — we survey and quote silicone render in Purley (CR8) and nearby Coulsdon, South Croydon and Wallington, with a fixed written price before any work starts.
