Before we quote in Surbiton
We also cover New Malden and Esher, close to Surbiton. 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.
We bring finish samples to Surbiton surveys so colours can be judged in daylight against your roof and windows.

England: planning and regulations
For a house in Surbiton, 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.
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 insulated render the same as EWI?
Yes — insulated render is the everyday name for a rendered EWI system. Some people also use it for thin thermal renders containing aerogel or cork, which are applied 20–40mm thick on heritage walls. They insulate far less than board systems, so we treat them as a specialist option.

Insulated render in Surbiton: questions
Does insulated render need painting?
Through-coloured silicone and acrylic renders don't need painting. Mineral renders are usually painted with a compatible masonry paint.
Will my house look different?
Yes, if it was brick or pebble dash. If you want to keep a brick look, a brick-slip finish over the insulation is an option.
Can insulated render be applied in winter?
Only in suitable weather — typically above 5°C and rising, with no frost or rain during curing. Winter programmes allow for lost days.
