Before we quote in Barry
As well as Barry itself, we quote in Penarth, Cardiff and Caerphilly. Barry sits around 7 miles from Cardiff. 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 South Glamorgan: 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 Barry with low pressure only, so thin-coat and EWI finishes aren't damaged.

Permissions in Wales
Small repairs and cleaning in Barry normally need no approvals. Listed buildings are the exception — even minor external work can need consent.
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 Barry: questions
Do you need scaffolding?
Usually not for a two-storey house; poles and low-pressure equipment reach most walls.
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.
Do you cover Barry?
Yes — we survey and quote render cleaning in Barry (CF63) and nearby Penarth, Cardiff and Caerphilly, with a fixed written price before any work starts.
