Local considerations in County Antrim
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.
For County Antrim homes with faded render, we price a clean and a clean-and-refresh option.

Permissions 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.
Listed buildings are the exception: even small external repairs can need listed building consent, so tell us if your property is listed.
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 County Antrim: questions
Is render cleaning safe for EWI?
Yes, using low pressure and products suitable for thin-coat render.
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.
Do you cover all of County Antrim?
Yes. We survey and quote render cleaning across County Antrim, including Belfast, Lisburn, Newtownabbey, Carrickfergus, Ballymena.
Do I need planning permission in Northern Ireland?
In Northern Ireland, permitted development is set by the Planning (General Permitted Development) Order (NI) 2015. We check your address before quoting.
