Local considerations in Magherafelt
We also cover Cookstown and Ballymena, close to Magherafelt. Magherafelt is about 33 miles from 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.
We bring brick slip samples to Magherafelt surveys so you can compare them with neighbouring houses.

Permissions in Northern Ireland
For Magherafelt homes, the council's planning office has the final say on external changes; conservation areas, flats and listed buildings need an application or consent.
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.

Brick slip EWI in Magherafelt: questions
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.
Is a brick slip finish more expensive?
Yes — roughly £70–£120 per m² more than render, because of materials and slower installation.
Can I mix brick slips and render?
Yes. A brick plinth or ground floor with render above is a common combination.
Do you cover Magherafelt?
Yes — we survey and quote brick slip finishes in Magherafelt (BT45) and nearby Cookstown, Ballymena and Antrim, with a fixed written price before any work starts.
