Walthamstow: walls, weather and approvals
We cover Walthamstow and nearby Leytonstone, Tottenham and Woodford Green. 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.
Where an EWI system in Walthamstow is still under guarantee, we'll suggest checking those terms before booking us.

Approvals in England
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 Walthamstow: questions
Why is my EWI cracking?
Common causes are missing movement joints, poor mesh overlap, fixing problems or movement in the wall. We look for the cause rather than filling the crack.
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.
