What we look for in Kelso
We cover Kelso and nearby Galashiels, Hawick and Peebles. Kelso sits around 18 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.
We plan EWI in Kelso around the details that cause trouble later — cills, eaves, downpipes and the base of the wall above the damp-proof course.

Permissions in Scotland
Scottish householder rules mean many Kelso jobs that change the outside of a house need a planning application; we confirm the position before quoting.
Where a building warrant is needed for Kelso 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 Kelso: 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.
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 Kelso?
Yes — we survey and quote external wall insulation in Kelso (TD5) and nearby Galashiels, Hawick and Peebles, with a fixed written price before any work starts.
