Local considerations in Exeter
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 terraced homes in Exeter with attractive brick fronts, one approach is to insulate the front internally and the rear externally.

England: planning and regulations
Planning isn't usually involved with internal insulation. Building control is, once more than half of a wall is treated, and listed buildings need listed building consent.
What are the risks with internal insulation?
Insulating inside makes the masonry colder, so moisture risk rises. Weak points are where floor joists bear into the wall, window reveals and corners. A condensation risk check for the build-up, a continuous vapour control layer where specified, and returning insulation into reveals deal with most of it.

Internal wall insulation in Exeter: questions
What happens to my radiators and sockets?
They're taken off and refitted on the new wall face. Electrical work is done by a qualified electrician.
Can I stay in the house?
Yes, but each room is out of use while it's worked on, typically 3–5 days.
Is internal insulation cheaper than external?
Per m² usually yes, but the cost of moving fittings and redecorating narrows the gap on whole-house jobs.
Do you cover Exeter?
Yes — we survey and quote internal wall insulation in Exeter (EX2) and nearby Exmouth, Newton Abbot and Torquay, with a fixed written price before any work starts.
