What's included

- Most system-built homes have thin, cold walls and no fillable cavity
- EWI is not a structural repair for PRC houses designated defective

Exeter: walls, weather and approvals
We cover Exeter and nearby Exmouth, Newton Abbot and Torquay. Exeter is about 36 miles from Plymouth. 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.
Parts of Devon fall in the higher wind-driven rain exposure bands, especially coastal and upland sites, so render specification, movement joints and detailing at cills, verges and the base of the wall matter more than usual.
For concrete houses in Exeter, we report any visible spalling or cracking before quoting the insulation, not after.

Approvals in England
For a house in Exeter, 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.
How do I know if my house is non-traditional?
Clues include concrete panels or posts visible at corners, a smooth concrete or rendered finish on houses of a 1940s–1960s estate, steel sheeting on the upper storey, or a mortgage valuation that mentioned the construction type. Common types include Wimpey no-fines (poured concrete), Airey and Cornish Unit (precast reinforced concrete), Reema, Orlit and BISF (steel frame). We identify the type during the survey.

Non-traditional houses in Exeter: questions
What if my neighbour isn't insulating?
We finish the system neatly at the boundary with a closing detail so the neighbouring house isn't affected and can be joined later.
Will EWI make my house mortgageable?
It can make a house more attractive and better insulated, but it does not replace a certified structural repair where a lender requires one. Ask your lender before relying on it.
Can you insulate a Wimpey no-fines house?
Yes. No-fines houses have solid poured-concrete walls with no cavity, so EWI is the usual route. The survey checks the concrete condition first.
Do you cover Exeter?
Yes — we survey and quote non-traditional house insulation in Exeter (EX2) and nearby Exmouth, Newton Abbot and Torquay, with a fixed written price before any work starts.
