Homes and walls in Coleraine
We also cover Limavady and Ballymena, close to Coleraine. It's roughly 27 miles from Coleraine to Derry~Londonderry, the largest town in County 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.
Extensions and new blockwork in Coleraine are where monocouche makes most sense.

Planning and building control in Northern Ireland
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.
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.
Why does monocouche sometimes look patchy?
Colour variation (often called shading) can appear if it's applied in poor weather, on walls with uneven suction, or in sections on different days. Working an elevation in one go in suitable conditions keeps the colour even.

Monocouche render in Coleraine: questions
Is monocouche waterproof?
It's water-resistant and sheds rain, while still allowing some vapour through.
Does monocouche need painting?
No — it's through-coloured. Cleaning every few years keeps it looking fresh.
Monocouche or silicone for an extension?
Both work on new blockwork. Silicone over a base coat costs a little more but tends to stay cleaner.
