What we look for in Coleraine
We also cover Limavady and Ballymena, close to Coleraine. Coleraine is about 27 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.
Schools and community buildings around Coleraine are usually phased by elevation, with noisy stages in holidays where possible.

Planning and building control in Northern Ireland
Before quoting in Coleraine, we check whether the property is listed or in a conservation area, which changes what needs planning permission in Northern Ireland.
Council building control in Northern Ireland checks insulation work of this kind; the quote says how the application is handled.
On taller buildings in Northern Ireland we specify non-combustible mineral wool systems and confirm the classification with building control, in line with Technical Booklet E.
How is the work programmed?
Work is split by elevation so entrances and fire exits stay usable. For schools, noisy and access-heavy stages are planned around holidays where possible. Health and safety duties under CDM 2015 are agreed at the start, including who acts as principal contractor.
