Before we quote in Greenock
We also cover Helensburgh and Dunoon, close to Greenock. Greenock is about 20 miles from Glasgow. 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.
Parts of Greater Glasgow 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.
For homes in Greenock, the survey starts with the wall itself: solid brick, stone or concrete, and whether any old render is sound enough to insulate over.

Planning and building control in Scotland
Scottish householder rules mean many Greenock 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 Greenock 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 Greenock: 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.
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.
