Devon: walls, weather and approvals
The South West has many stone and solid-walled cottages, exposed coastal properties and a share of post-war system-built houses, including types such as the Cornish Unit.
Parts of Devon fall in the higher wind-driven rain exposure bands, especially coastal and upland sites, so render specification, movement joints and detailing at cills, verges and the base of the wall matter more than usual.

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.
Listed buildings are the exception: even small external repairs can need listed building consent, so tell us if your property is listed.
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 Devon: questions
Will the green come back?
The biocide slows regrowth considerably, but shaded, damp walls can need retreating every few years.
Can faded render be refreshed?
Yes — a compatible silicone paint restores colour without making the wall less breathable.
Is render cleaning safe for EWI?
Yes, using low pressure and products suitable for thin-coat render.
Do you cover all of Devon?
Yes. We survey and quote render cleaning across Devon, including Plymouth, Exeter, Torquay, Paignton, Newton Abbot.
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.
