Rhondda: walls, weather and approvals
Surveys in Rhondda also cover the surrounding CF42 district and towns such as Aberdare and Pontypridd. South Wales has long runs of solid-wall valley terraces, Victorian and Edwardian town housing and post-war council estates.
Parts of Mid 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.
Shaded and north-facing walls in Rhondda often need render cleaning sooner than sunny elevations.

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.
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 Rhondda: questions
Is render cleaning safe for EWI?
Yes, using low pressure and products suitable for thin-coat render.
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.
