Homes and walls in West Glamorgan
South Wales has long runs of solid-wall valley terraces, Victorian and Edwardian town housing and post-war council estates.
Parts of West Glamorgan 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.
We clean render in West Glamorgan with low pressure only, so thin-coat and EWI finishes aren't damaged.

Planning and building control in Wales
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 West Glamorgan: questions
Do you need scaffolding?
Usually not for a two-storey house; poles and low-pressure equipment reach most walls.
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 cover all of West Glamorgan?
Yes. We survey and quote render cleaning across West Glamorgan, including Swansea, Neath, Briton Ferry, Port Talbot, Gorseinon.
Do I need planning permission in Wales?
Permitted development rules for houses in Wales are similar to England's: a similar-appearance finish on a house is often permitted, while conservation areas, National Parks, Areas of Outstanding Natural Beauty, flats, commercial buildings and listed buildings need permission or consent. We check your address before quoting.
