Local considerations in Northolt
As well as Northolt itself, we quote in Greenford, Harrow and Southall. 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 Northolt, we'll show you what adding insulation under the silicone would cost at the same time.

Permissions in England
Before quoting in Northolt, 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.
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 Northolt: 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 I paint silicone render later?
Yes, with a compatible silicone paint, though through-coloured render rarely needs it.
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.
Do you cover Northolt?
Yes — we survey and quote silicone render in Northolt (UB5) and nearby Greenford, Harrow and Southall, with a fixed written price before any work starts.
