What we look for in Derry~Londonderry
We also cover Strabane and Limavady, close to Derry~Londonderry. Northern Ireland has many rendered and pebble-dashed homes, older solid-walled rural houses, and estates built by the Housing Executive.
Parts of County Londonderry 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.
On brick terraces in Derry~Londonderry, slips can insulate the wall while keeping the street's look.

Planning and building control in Northern Ireland
Before quoting in Derry~Londonderry, we check whether the property is listed or in a conservation area, which changes what needs planning permission in Northern Ireland.
External wall insulation is building work under the Building Regulations (Northern Ireland) 2012, so council building control is involved, with Technical Booklet F1 covering 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.
