Homes and walls in Bangor (Gwynedd)
Surveys in Bangor (Gwynedd) also cover the surrounding LL57 district and towns such as Llangefni and Caernarfon. North Wales has many solid stone and slate-built homes, Victorian seaside terraces and post-war council estates.
Parts of Gwynedd 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.

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 Bangor (Gwynedd): questions
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.
Will the green come back?
The biocide slows regrowth considerably, but shaded, damp walls can need retreating every few years.
