Belfast: walls, weather and approvals
As well as Belfast itself, we quote in Castlereagh, Newtownabbey and Holywood. Northern Ireland has many rendered and pebble-dashed homes, older solid-walled rural houses, and estates built by the Housing Executive.
Parts of County Antrim 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.
Shaded and north-facing walls in Belfast often need render cleaning sooner than sunny elevations.

Approvals in Northern Ireland
Small repairs and cleaning in Belfast normally need no approvals. Listed buildings are the exception — even minor external work can need consent.
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 Belfast: questions
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.
Do you need scaffolding?
Usually not for a two-storey house; poles and low-pressure equipment reach most walls.
Do you cover Belfast?
Yes — we survey and quote render cleaning in Belfast (BT1) and nearby Castlereagh, Newtownabbey and Holywood, with a fixed written price before any work starts.
