Coleraine: walls, weather and approvals
We cover Coleraine and nearby Limavady, Ballymena and Magherafelt. Coleraine sits around 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.
Freeholders and managing agents in Coleraine get a written specification and pricing they can share with owners.

Northern Ireland: planning and regulations
For Coleraine homes, the council's planning office has the final say on external changes; conservation areas, flats and listed buildings need an application or consent.
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.
For flats, the lease or management agreement sets how owners agree to the work and share its cost.
How disruptive is it for residents?
Most work happens from scaffolding outside. Residents may need to allow brief access to extend window cills, vents or flues from the inside. We provide a notice for residents covering dates, scaffold, and how to raise concerns.

Flats and blocks in Coleraine: questions
Can one flat have external wall insulation on its own?
Rarely. The outside walls are usually owned by the freeholder, the result would look patchy, and planning is unlikely. Whole-building schemes are the norm.
Do flats need planning permission for EWI?
Yes. Permitted development rights for external alterations apply to houses, not flats or maisonettes, so an application is needed.
Do you cover Coleraine?
Yes — we survey and quote EWI for flats and blocks in Coleraine (BT52) and nearby Limavady, Ballymena and Magherafelt, with a fixed written price before any work starts.
