Non-traditional and concrete house insulation in Plymouth
From Plymouth to Plymstock, we price non-traditional house insulation after a measured survey — no guesswork, and no work starts until the price is agreed in writing. For concrete houses in Plymouth, we report any visible spalling or cracking before quoting the insulation, not after.
- Free survey in PL2 and nearby
- Guide price from £120 per m² + scaffold, 0% VAT
- Fixed written price before work starts

Postcode, service and a phone number is all we need.
What you get
- EWI is not a structural repair for PRC houses designated defective
- The survey identifies the construction type before anything is specified
- EWI improves comfort and can renew a tired concrete exterior
- Steel-framed BISF houses need care around the upper-storey cladding

Before we quote in Plymouth
We cover Plymouth and nearby Plymstock, Paignton and Newton Abbot. 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.
Where one half of a pair in Plymouth is insulated and the other isn't, we detail the boundary so the neighbour can join later.

Planning and building control in England
For a house in Plymouth, 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.
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 Plymouth: 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 Plymouth?
Yes — we survey and quote non-traditional house insulation in Plymouth (PL2) and nearby Plymstock, Paignton and Newton Abbot, with a fixed written price before any work starts.
