Homes and walls in Dorchester
We also cover Weymouth and Bridport, close to Dorchester. Dorchester is about 24 miles from Bournemouth. The South West has many stone and solid-walled cottages, exposed coastal properties and a share of post-war system-built houses, including types such as the Cornish Unit.
Exposure to wind-driven rain varies across Dorset: 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.
We bring finish samples to Dorchester surveys so colours can be judged in daylight against your roof and windows.

Permissions in England
For a house in Dorchester, 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.

Insulated render in Dorchester: questions
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.
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.
