Non-traditional and concrete house insulation in Cwmbran
From Cwmbran to Pontypool, 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 Cwmbran, we report any visible spalling or cracking before quoting the insulation, not after.
- Free survey in NP44 and nearby
- Guide price from £120 per m² + scaffold, 0% VAT

Included as standard

Local considerations in Cwmbran
Surveys in Cwmbran also cover the surrounding NP44 district and towns such as Pontypool and Risca. It's roughly 5 miles from Cwmbran to Newport (Gwent), the largest town in Gwent. South Wales has long runs of solid-wall valley terraces, Victorian and Edwardian town housing and post-war council estates.
Exposure to wind-driven rain varies across Gwent: 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.
Where a home in Cwmbran is system-built, the first job is confirming the construction type.

Wales: planning and regulations
Householder rules in Wales are similar to England's: in Cwmbran, a similar-looking finish on a house is often permitted, but conservation areas, flats and listed buildings need permission or consent.
Building control in Wales applies to most insulation and re-rendering jobs of this size; the quote states who submits the notice.
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 Cwmbran: 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.
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.
Do you cover Cwmbran?
Yes — we survey and quote non-traditional house insulation in Cwmbran (NP44) and nearby Pontypool, Risca and Newport (Gwent), with a fixed written price before any work starts.
