Homes and walls in Castlereagh
As well as Castlereagh itself, we quote in 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.
