What you get

- EWI improves comfort and can renew a tired concrete exterior
- Steel-framed BISF houses need care around the upper-storey cladding
Local considerations in Gorseinon
As well as Gorseinon itself, we quote in Llanelli, Swansea and Ammanford. It's roughly 5 miles from Gorseinon to Swansea, the largest town in West Glamorgan. South Wales has long runs of solid-wall valley terraces, Victorian and Edwardian town housing and post-war council estates.
Parts of West Glamorgan 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 a home in Gorseinon is system-built, the first job is confirming the construction type.

Permissions in Wales
Householder rules in Wales are similar to England's: in Gorseinon, 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.
How do I know if my house is non-traditional?
Clues include concrete panels or posts visible at corners, a smooth concrete or rendered finish on houses of a 1940s–1960s estate, steel sheeting on the upper storey, or a mortgage valuation that mentioned the construction type. Common types include Wimpey no-fines (poured concrete), Airey and Cornish Unit (precast reinforced concrete), Reema, Orlit and BISF (steel frame). We identify the type during the survey.

Non-traditional houses in Gorseinon: questions
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.
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.
Do you cover Gorseinon?
Yes — we survey and quote non-traditional house insulation in Gorseinon (SA4) and nearby Llanelli, Swansea and Ammanford, with a fixed written price before any work starts.
