What we look for in Greater London
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 Greater London with compatible materials.

Planning and building control 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.
Listed buildings are the exception: even small external repairs can need listed building consent, so tell us if your property is listed.
How is damaged EWI repaired?
The damaged area is cut back to sound render and board. Wet or crushed insulation is replaced, a new base coat with overlapping mesh is applied, then primer and a matching finish. The repair overlaps the existing mesh so it's reinforced like the original.

EWI repairs in Greater London: 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.
Will the repair be visible?
Usually slightly, because the existing finish has weathered. A recoat of the elevation evens it out.
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 all of Greater London?
Yes. We survey and quote EWI repairs across Greater London, including Islington, Bexley, Archway, Sutton, Croydon.
Do I need planning permission in England?
For houses, external wall insulation and render are often permitted development where the finish looks similar to the existing walls. We check your address before quoting.
