Before we quote 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.
On brick terraces in County Down, slips can insulate the wall while keeping the street's look.

Approvals in Northern Ireland
In Northern Ireland, permitted development is set by the Planning (General Permitted Development) Order (NI) 2015. Changing the external appearance of a house may need permission, and conservation areas, flats, commercial buildings and listed buildings need planning permission or listed building consent. Check with your council's planning office.
Insulating external walls is building work under the Building Regulations (Northern Ireland) 2012, handled by council building control, with Technical Booklet F1 covering conservation of fuel and power in dwellings.
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 County Down: questions
Do brick slips fall off?
Not when installed to the system manufacturer's specification, with the right adhesive, fixings and pointing.
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.
Can I mix brick slips and render?
Yes. A brick plinth or ground floor with render above is a common combination.
Do you cover all of County Down?
Yes. We survey and quote brick slip finishes 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.
