What we look for in Castlereagh
We cover Castlereagh and nearby Belfast, Holywood and Newtownabbey. Castlereagh sits around 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.
On brick terraces in Castlereagh, slips can insulate the wall while keeping the street's look.

Approvals in Northern Ireland
In Northern Ireland, permitted development is set by the 2015 Order; in Castlereagh, changing a house's external appearance, and any work on flats or listed buildings, may need permission, so we check with the council.
Building control applies to insulation and major re-rendering in Northern Ireland, and the work is signed off by the council.
How is the brick slip system built up?
Insulation boards are fixed as for any EWI, followed by a reinforced base coat. The slips are bonded with the system adhesive, spaced for joints, then pointed. Corners use L-shaped slips so the edge looks like a solid brick.

Brick slip EWI in Castlereagh: questions
Do brick slips fall off?
Not when installed to the system manufacturer's specification, with the right adhesive, fixings and pointing.
Can I mix brick slips and render?
Yes. A brick plinth or ground floor with render above is a common combination.
Will brick slips match my neighbours' brick?
We source slips to get close in colour and texture and show samples beforehand, but an exact match to weathered brick isn't always possible.
Do you cover Castlereagh?
Yes — we survey and quote brick slip finishes in Castlereagh (BT5) and nearby Belfast, Holywood and Newtownabbey, with a fixed written price before any work starts.
