Castlereagh: walls, weather and approvals
We cover Castlereagh and nearby Belfast, Holywood and Newtownabbey. Castlereagh is about 11 miles from Bangor (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 plan monocouche in Castlereagh for settled weather so each elevation can be finished in one go.

Permissions in Northern Ireland
For Castlereagh homes, the council's planning office has the final say on external changes; conservation areas, flats and listed buildings need an application or consent.
Council building control in Northern Ireland checks insulation work of this kind; the quote says how the application is handled.
Can monocouche go over insulation?
No — insulation systems use a mesh-reinforced base coat and a thin-coat finish instead. If you want insulation as well as a new finish, see insulated render.

Monocouche render in Castlereagh: questions
Monocouche or silicone for an extension?
Both work on new blockwork. Silicone over a base coat costs a little more but tends to stay cleaner.
Is monocouche waterproof?
It's water-resistant and sheds rain, while still allowing some vapour through.
Does monocouche need painting?
No — it's through-coloured. Cleaning every few years keeps it looking fresh.
