Homes and walls in Wiltshire
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.
Exposure to wind-driven rain varies across Wiltshire: sheltered town streets fare better than walls on high ground or facing the prevailing weather, and the render, beads and cill details are chosen with that in mind.
For Wiltshire homes with faded render, we price a clean and a clean-and-refresh option.

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.
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 Wiltshire: questions
Can faded render be refreshed?
Yes — a compatible silicone paint restores colour without making the wall less breathable.
Will the green come back?
The biocide slows regrowth considerably, but shaded, damp walls can need retreating every few years.
Do you need scaffolding?
Usually not for a two-storey house; poles and low-pressure equipment reach most walls.
Do you cover all of Wiltshire?
Yes. We survey and quote render cleaning across Wiltshire, including Swindon, Salisbury, Trowbridge, Chippenham.
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.
