Free survey in Swansea
Postcode, service and a phone number is all we need.
What you get
- Steel-framed BISF houses need care around the upper-storey cladding
- Most system-built homes have thin, cold walls and no fillable cavity
- The survey identifies the construction type before anything is specified
- EWI is not a structural repair for PRC houses designated defective
What we look for in Swansea
As well as Swansea itself, we quote in Briton Ferry, Gorseinon and Neath. 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.
For concrete houses in Swansea, we report any visible spalling or cracking before quoting the insulation, not after.

Planning and building control in Wales
For homes in Swansea, the local planning authority decides any borderline cases; changing a brick house to render, or work on flats, usually needs an application in Wales.
Building control in Wales applies to most insulation and re-rendering jobs of this size; the quote states who submits the notice.
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 Swansea: 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.
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 Swansea?
Yes — we survey and quote non-traditional house insulation in Swansea (SA1) and nearby Briton Ferry, Gorseinon and Neath, with a fixed written price before any work starts.
