Before we quote in Ayr
Surveys in Ayr also cover the surrounding KA7 district and towns such as Irvine and Kilmarnock. Ayr is about 12 miles from 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.
We plan EWI in Ayr around the details that cause trouble later — cills, eaves, downpipes and the base of the wall above the damp-proof course.

Approvals in Scotland
For Ayr 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.
Scotland's building standards cover changes to external wall construction; we check whether your job in Ayr needs a warrant.
How does external wall insulation work?
Heat moves out through a wall faster when the wall is solid or poorly insulated. EWI wraps the outside face in a continuous layer of insulation, so the masonry stays on the warm side and the cold bridges at floor and party-wall junctions are reduced. The boards are bonded with adhesive and, on most walls, mechanically fixed. A base coat with an embedded glass-fibre mesh goes over the top, then a primer and the decorative finish.
Because the wall itself sits inside the insulation, it stays warmer and drier, and the rooms keep their full size. That is the main difference from internal insulation.

External wall insulation in Ayr: 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 long does external wall insulation last?
A well-installed render system is commonly expected to last 25–30 years or more, with occasional cleaning and inspection of sealants. The system manufacturer's documentation states the expected service life for the specific build-up.
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 Ayr?
Yes — we survey and quote external wall insulation in Ayr (KA7) and nearby Irvine, Kilmarnock and Newton Mearns, with a fixed written price before any work starts.
