Homes and walls 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.
We bring finish samples to Barnes surveys so colours can be judged in daylight against your roof and windows.

England: planning and regulations
Planning in Barnes follows England's national rules: similar-looking finishes on houses are usually permitted, while flats, commercial premises, conservation areas and streets under an Article 4 direction need an application.
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.
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 Barnes: questions
How long does insulated render last?
Typically 25–30 years or more with maintenance; the manufacturer's documentation sets the service life for the specific system.
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.
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.
Do you cover Barnes?
Yes — we survey and quote insulated render in Barnes (SW13) and nearby Chiswick, Putney and Fulham, with a fixed written price before any work starts.
