Before we quote in Richmond
We also cover Isleworth and Hounslow, close to Richmond. 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.
Shaded and north-facing walls in Richmond often need render cleaning sooner than sunny elevations.

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.
How long does cleaned render stay clean?
It depends on shade, trees and exposure. Many walls stay clean for several years after a biocide treatment. North-facing, shaded and damp walls may need treating more often.

Render cleaning in Richmond: questions
Is render cleaning safe for EWI?
Yes, using low pressure and products suitable for thin-coat render.
Do you need scaffolding?
Usually not for a two-storey house; poles and low-pressure equipment reach most walls.
Will the green come back?
The biocide slows regrowth considerably, but shaded, damp walls can need retreating every few years.
