Homes and walls in Derry~Londonderry
We cover Derry~Londonderry and nearby Strabane, Limavady and Coleraine. Northern Ireland has many rendered and pebble-dashed homes, older solid-walled rural houses, and estates built by the Housing Executive.
Parts of County Londonderry 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 Derry~Londonderry with low pressure only, so thin-coat and EWI finishes aren't damaged.

Approvals in Northern Ireland
Repairs, cleaning and like-for-like patching don't usually need planning permission. If the work grows into replacing most of a wall's render, we check with the council's building standards or building control team first.
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 Derry~Londonderry: 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.
