What we look for in Worthing
We also cover Portslade and Littlehampton, close to Worthing. Worthing sits around 22 miles from Crawley. 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.
Exposure to wind-driven rain varies across West Sussex: sheltered town streets fare better than walls on high ground or facing the prevailing weather, and the render, beads and cill details are chosen with that in mind.
For houses in Worthing with shallow eaves, the insulated render thickness is planned with the roofline in mind.

Planning and building control in England
For a house in Worthing, 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.
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.

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.
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.
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.
