Carshalton: walls, weather and approvals
We also cover Wallington and Sutton, close to Carshalton. 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 Carshalton with compatible materials.

What causes EWI to fail?
Most problems start at details: cills that are too short or not sealed, unsealed pipe penetrations, missing drip beads, ground levels too close to the base track, or impact at low level. Where a defect is widespread, we report the likely cause before quoting.

EWI repairs in Carshalton: 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.
Can damaged EWI be patched?
Yes, provided the board behind is dry and sound. Wet or crushed board is cut out and replaced.
Do you cover Carshalton?
Yes — we survey and quote EWI repairs in Carshalton (SM5) and nearby Wallington, Sutton and Mitcham, with a fixed written price before any work starts.
