Before we quote in Finchley
As well as Finchley itself, we quote in Muswell Hill, Cricklewood and Kilburn. 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.
Low-level impact damage near drives and bins is a typical EWI repair, and we fix it in Finchley with compatible materials.

England: planning and regulations
Repairs, cleaning and like-for-like patching don't usually need planning permission or building control. If repairs grow into re-rendering more than half of a wall, Building Regulations energy rules can apply.
Do you repair systems you didn't install?
Yes. We identify the system type where possible and use compatible materials. If your system is under a manufacturer's or installer's guarantee, check its terms before any third party works on it.

EWI repairs in Finchley: questions
Will the repair be visible?
Usually slightly, because the existing finish has weathered. A recoat of the elevation evens it out.
Can damaged EWI be patched?
Yes, provided the board behind is dry and sound. Wet or crushed board is cut out and replaced.
My EWI was installed under a grant — who repairs it?
First check the guarantee paperwork and contact the original installer or guarantee provider. If that route isn't available, we can quote.
Do you cover Finchley?
Yes — we survey and quote EWI repairs in Finchley (N3) and nearby Muswell Hill, Cricklewood and Kilburn, with a fixed written price before any work starts.
