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
- The survey identifies the construction type before anything is specified
Homes and walls in Truro
We also cover Falmouth and Redruth, close to Truro. It's roughly 8 miles from Truro to Redruth, the largest town in Cornwall. 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 Cornwall 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 Truro, we report any visible spalling or cracking before quoting the insulation, not after.

Planning and building control in England
Before quoting in Truro, we check whether the property is in a conservation area, under an Article 4 direction or listed, because that decides whether changing the outside needs planning permission.
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.
What does the work involve?
After checking the wall condition, any spalling concrete or corroded steel is reported before boards go on. Fixings are chosen for the substrate — concrete, steel-framed panels or mixed constructions — and the system is detailed around eaves, cills and the junction with neighbouring properties, which may not be insulated.

Non-traditional houses in Truro: questions
Can you put EWI on a BISF house?
Yes, with care. The steel frame and upper-storey cladding need a system and fixing method designed for that construction, and the condition of the frame should be understood first.
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 Truro?
Yes — we survey and quote non-traditional house insulation in Truro (TR1) and nearby Falmouth, Redruth and Newquay, with a fixed written price before any work starts.
