What's included

- Fixing design depends on the panel or frame behind the wall
- EWI is not a structural repair for PRC houses designated defective
Before we quote in Heston
We also cover Hounslow and Isleworth, close to Heston. 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 concrete houses in Heston, we report any visible spalling or cracking before quoting the insulation, not after.

Permissions in England
For a house in Heston, 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.
Insulating or re-rendering more than half of a wall's area brings in Part L of the Building Regulations, so building control is notified and the wall is upgraded to about 0.30 W/m²K where practical.
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 Heston: questions
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.
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 Heston?
Yes — we survey and quote non-traditional house insulation in Heston (TW5) and nearby Hounslow, Isleworth and Southall, with a fixed written price before any work starts.
