Local considerations in Merthyr Tydfil
We cover Merthyr Tydfil and nearby Aberdare, Rhondda and Ebbw Vale. Merthyr Tydfil sits around 7 miles from Rhondda. 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.
We clean render in Merthyr Tydfil with low pressure only, so thin-coat and EWI finishes aren't damaged.

Permissions in Wales
Small repairs and cleaning in Merthyr Tydfil normally need no approvals. Listed buildings are the exception — even minor external work can need consent.
Why not pressure wash render?
Thin-coat renders are only 1–2mm thick. High-pressure jetting can erode the texture, strip colour, force water behind beads and cracks, and damage the insulation system underneath. A soft wash uses chemistry rather than pressure to do the work.

Render cleaning in Merthyr Tydfil: 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.
Is render cleaning safe for EWI?
Yes, using low pressure and products suitable for thin-coat render.
