External wall insulation in Hamilton
From Hamilton to Motherwell, we price external wall insulation after a measured survey — no guesswork, and no work starts until the price is agreed in writing. For homes in Hamilton, the survey starts with the wall itself: solid brick, stone or concrete, and whether any old render is sound enough to insulate over.

Before we quote in Hamilton
We cover Hamilton and nearby Motherwell, Bellshill and Wishaw. It's roughly 6 miles from Hamilton to East Kilbride, the largest town in Lanarkshire. West Central Scotland has sandstone tenements, interwar and post-war council housing including no-fines and other system-built types, and many harled (roughcast) houses.
Exposure to wind-driven rain varies across Lanarkshire: 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 Hamilton around the details that cause trouble later — cills, eaves, downpipes and the base of the wall above the damp-proof course.

Planning and building control in Scotland
For Hamilton 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 Hamilton work, it's obtained before installation starts, and the quote says who arranges it.
What does the survey check before EWI is specified?
- Wall construction and condition, including any damp, cracking or loose render
- Ground levels and the damp-proof course, so the system starts above splash height
- Eaves depth, verges and whether the roofline needs extending
- Window positions, cill depths and reveal space
- Services on the wall: gas, electric meters, flues, soil pipes, satellite dishes and lights
- Planning and Building Regulations position for your property and nation

External wall insulation in Hamilton: questions
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.
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.
