What we look for in Sunbury-on-Thames
We cover Sunbury-on-Thames and nearby Walton-on-Thames, Hanworth and Ashford (Surrey). Sunbury-on-Thames is about 8 miles from Woking. Homes across the South East range from inter-war semis and post-war estates, which are mostly cavity-walled, to older solid-walled cottages and Victorian town terraces.
Much of Surrey 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.
For houses in Sunbury-on-Thames with shallow eaves, the insulated render thickness is planned with the roofline in mind.

England: planning and regulations
For a house in Sunbury-on-Thames, 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.
Can I choose two colours?
Yes. Many owners pick a main colour with a contrasting plinth, entrance surround or bay. Feature bands and recessed details can be formed in the insulation before rendering.

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.
