Before we quote in Thurso
We cover Thurso and nearby Wick, Kirkwall and Lossiemouth. Thurso is about 81 miles from Inverness. The Highlands and Islands have many exposed stone and harled homes, timber-framed houses and scattered rural properties.
Parts of Highland 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.
Whole-house jobs and single elevations are both quoted in Thurso; a cold gable or rear wall can be done on its own where it suits.

Permissions in Scotland
In Scotland, permitted development for external wall changes is narrower, so in Thurso we check with the council's planning team where the appearance changes, and always for flats, tenements and conservation areas.
Scotland's building standards cover changes to external wall construction; we check whether your job in Thurso needs a warrant.
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 Thurso: questions
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.
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 Thurso?
Yes — we survey and quote external wall insulation in Thurso (KW14) and nearby Wick, Kirkwall and Lossiemouth, with a fixed written price before any work starts.
