Homes and walls in Caerphilly
As well as Caerphilly itself, we quote in Risca, Pontypridd and Cardiff. Caerphilly sits around 9 miles from Newport (Gwent). South Wales has long runs of solid-wall valley terraces, Victorian and Edwardian town housing and post-war council estates.
Exposure to wind-driven rain varies across Gwent: 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.
We clean render in Caerphilly with low pressure only, so thin-coat and EWI finishes aren't damaged.

Wales: planning and regulations
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 Caerphilly: 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.
Can faded render be refreshed?
Yes — a compatible silicone paint restores colour without making the wall less breathable.
Do you cover Caerphilly?
Yes — we survey and quote render cleaning in Caerphilly (CF83) and nearby Risca, Pontypridd and Cardiff, with a fixed written price before any work starts.
