Homes and walls in Hayes
We cover Hayes and nearby Southall, Heston and Greenford. London's housing includes a large stock of Victorian and Edwardian solid-wall terraces, inter-war semis and post-war blocks, and conservation areas cover many streets — so planning is often the first question for external work.
Much of Greater London sits in the lower wind-driven rain exposure bands, which keeps the choice of finishes wide — though hilltop, coastal and exposed gable walls can still need a tougher specification, so we check the actual site.
For older stone and early brick properties in Hayes, we look at a wood fibre and lime build-up first.

Approvals in England
For a house in Hayes, external insulation or render is often permitted development if it looks similar to the existing walls; conservation areas, flats, commercial buildings and listed buildings need permission or consent, so we check your address first.
Building control applies once more than half of a wall is insulated or re-rendered, or more than a quarter of the whole building envelope, and your written quote says how that's handled.
What about listed buildings and conservation areas?
EWI on a listed building needs listed building consent and is often refused where the outside appearance matters. In conservation areas, rendering or cladding a house normally needs planning permission. Wood fibre and lime are more likely to be acceptable than foam and acrylic, but the council decides. We check before quoting.

Wood fibre EWI in Hayes: questions
Is wood fibre insulation fireproof?
No — it's a timber product. It chars rather than flaming readily, but it is combustible, so it's used on low-rise buildings within a tested system and never where non-combustible materials are required.
Can wood fibre go on a stone wall?
Yes, after levelling. Rubble stone is often uneven, so a levelling coat or adapted fixing method is used first.
Does wood fibre need a lime render?
It needs the render specified by the system manufacturer, which is usually lime or mineral based.
Do you cover Hayes?
Yes — we survey and quote wood fibre external wall insulation in Hayes (UB3) and nearby Southall, Heston and Greenford, with a fixed written price before any work starts.
