Homes and walls in Streatham
We also cover Mitcham and Brixton, close to Streatham. 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.
EWI repairs in Streatham start with finding where water or damage got in, not just covering it.

Permissions 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.
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 Streatham: questions
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.
Will the repair be visible?
Usually slightly, because the existing finish has weathered. A recoat of the elevation evens it out.
