Kilmarnock: walls, weather and approvals
We also cover Irvine and Ayr, close to Kilmarnock. South West Scotland has stone and harled houses, coastal towns and post-war council housing.
Parts of Ayrshire 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.
For homes in Kilmarnock, the survey starts with the wall itself: solid brick, stone or concrete, and whether any old render is sound enough to insulate over.

Approvals in Scotland
For Kilmarnock properties, flats and tenements need planning permission for external insulation, and a noticeable change of finish on a house often does too under Scottish rules.
Where a building warrant is needed for Kilmarnock work, it's obtained before installation starts, and the quote says who arranges it.
What finish can I have?
Most EWI is finished in a thin-coat silicone render in a through-coloured shade, with a 1–2mm grain. Acrylic, mineral (painted), dry-dash and brick-slip finishes are also available. Where planning wants a brick look, brick slips over the insulation keep the street appearance.

External wall insulation in Kilmarnock: questions
Does external wall insulation cause damp?
Not when it is specified and detailed properly. Problems usually come from poor detailing: no starter track above the damp-proof course, gaps at cills and penetrations, or a vapour-closed system on a wall that needs to breathe. The survey checks moisture, ground levels and the wall type before a system is chosen.
How much does external wall insulation cost?
Our guide price for EWI is £105–£170 per m² of wall depending on the system, plus scaffolding. A typical three-bed semi with EPS and silicone render comes to roughly £10,200–£17,700 for the whole house, including scaffold. Installing insulation in a home is zero-rated for VAT until 31 March 2027, so that's the total. You get a fixed written price after a free survey.
Can EWI go over pebble dash?
Usually yes. The dash is tested for adhesion and hollow areas; sound dash can be insulated over with additional mechanical fixings, while loose areas are removed first.
Do you cover Kilmarnock?
Yes — we survey and quote external wall insulation in Kilmarnock (KA3) and nearby Irvine, Ayr and Newton Mearns, with a fixed written price before any work starts.
