Non-traditional and concrete house insulation in Colwyn Bay
From Colwyn Bay to Llandudno, we price non-traditional house insulation after a measured survey — no guesswork, and no work starts until the price is agreed in writing. Where one half of a pair in Colwyn Bay is insulated and the other isn't, we detail the boundary so the neighbour can join later.
- Free survey in LL29 and nearby
- Guide price from £120 per m² + scaffold, 0% VAT
- Fixed written price before work starts

- The survey identifies the construction type before anything is specified
Before we quote in Colwyn Bay
As well as Colwyn Bay itself, we quote in Llandudno, Rhyl and Bangor (Gwynedd). Colwyn Bay sits around 35 miles from Wrexham. North Wales has many solid stone and slate-built homes, Victorian seaside terraces and post-war council estates.
Exposure to wind-driven rain varies across Clwyd: 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 Colwyn Bay is system-built, the first job is confirming the construction type.

Wales: planning and regulations
We check Colwyn Bay addresses for conservation areas and listing before quoting, because Welsh permitted development rules don't cover every external change.
Welsh Building Regulations expect walls to be upgraded when a substantial area is renewed, and building control signs the work off.
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 Colwyn Bay: 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 Colwyn Bay?
Yes — we survey and quote non-traditional house insulation in Colwyn Bay (LL29) and nearby Llandudno, Rhyl and Bangor (Gwynedd), with a fixed written price before any work starts.
