Non-traditional and concrete house insulation in Flint
From Flint to Deeside, 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 Flint is insulated and the other isn't, we detail the boundary so the neighbour can join later.
- Free survey in CH6 and nearby
- Guide price from £120 per m² + scaffold, 0% VAT
- Fixed written price before work starts
Free survey in Flint
Postcode, service and a phone number is all we need.

- Steel-framed BISF houses need care around the upper-storey cladding
Local considerations in Flint
Surveys in Flint also cover the surrounding CH6 district and towns such as Deeside and Buckley. It's roughly 15 miles from Flint to Wrexham, the largest town in Clwyd. 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 Flint is system-built, the first job is confirming the construction type.

Planning and building control in Wales
Householder rules in Wales are similar to England's: in Flint, a similar-looking finish on a house is often permitted, but conservation areas, flats and listed buildings need permission or consent.
In Wales, insulating or re-rendering more than half of a wall's area is treated as renovating a thermal element under Approved Document L (Wales), so building control is involved before work starts.
Does EWI fix mortgage problems with PRC houses?
Not on its own. Some precast reinforced concrete (PRC) house types were designated defective, and many lenders want a certified structural repair before they will lend. Insulation and render over the outside is not that repair. Other types, such as Wimpey no-fines, are generally treated differently. If mortgageability matters, speak to your lender or a surveyor before booking any work.

Non-traditional houses in Flint: 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.
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.
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 Flint?
Yes — we survey and quote non-traditional house insulation in Flint (CH6) and nearby Deeside, Buckley and Hawarden, with a fixed written price before any work starts.
