Local considerations in County Down
Northern Ireland has many rendered and pebble-dashed homes, older solid-walled rural houses, and estates built by the Housing Executive.
Exposure to wind-driven rain varies across County Down: 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 County Down 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.
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 Down: questions
Can faded render be refreshed?
Yes — a compatible silicone paint restores colour without making the wall less breathable.
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 all of County Down?
Yes. We survey and quote render cleaning across County Down, including Bangor (County Down), Castlereagh, Newtownards, Newry, Banbridge.
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.
