What we look for in Galashiels
We also cover Hawick and Kelso, close to Galashiels. Galashiels sits around 13 miles from Hawick. The Scottish Borders have stone-built towns and villages, rural cottages and some post-war estates.
Exposure to wind-driven rain varies across Scottish Borders: sheltered town streets fare better than walls on high ground or facing the prevailing weather, and the render, beads and cill details are chosen with that in mind.
For homes in Galashiels, the survey starts with the wall itself: solid brick, stone or concrete, and whether any old render is sound enough to insulate over.

Permissions in Scotland
For Galashiels 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 Galashiels 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 Galashiels: questions
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.
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.
