Before we quote in Powys
Mid Wales is largely rural, with stone farmhouses, cottages and market-town terraces, many of them solid-walled.
Parts of Powys 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.
For Powys homes with faded render, we price a clean and a clean-and-refresh option.

Permissions 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.
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 Powys: questions
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.
Is render cleaning safe for EWI?
Yes, using low pressure and products suitable for thin-coat render.
Do you cover all of Powys?
Yes. We survey and quote render cleaning across Powys, including Newtown, Brecon, Welshpool, Llandrindod Wells.
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.
