Local considerations in Belfast
We also cover Castlereagh and Newtownabbey, close to Belfast. 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.
If you're re-rendering in Belfast, we'll show you what adding insulation under the silicone would cost at the same time.

Approvals in Northern Ireland
In Northern Ireland, permitted development is set by the 2015 Order; in Belfast, changing a house's external appearance, and any work on flats or listed buildings, may need permission, so we check with the council.
Council building control in Northern Ireland checks insulation work of this kind; the quote says how the application is handled.
Is silicone render maintenance-free?
Not quite. It stays cleaner than most renders because water runs off and dries quickly, but north-facing or tree-shaded walls can still gather algae. A gentle biocide wash every few years keeps it looking new. Pressure washing is avoided because it can damage the surface.

Silicone render in Belfast: questions
Does silicone render crack?
The mesh-reinforced base coat and the render's flexibility make cracking much less likely than with sand and cement, but structural movement in the wall can still show through.
Can I paint silicone render later?
Yes, with a compatible silicone paint, though through-coloured render rarely needs it.
Can silicone render go over old render?
If the old render is sound and well bonded, often yes after cleaning and priming. Hollow or cracked areas are cut out and repaired first.
Do you cover Belfast?
Yes — we survey and quote silicone render in Belfast (BT1) and nearby Castlereagh, Newtownabbey and Holywood, with a fixed written price before any work starts.
