Homes and walls in Clydebank
We cover Clydebank and nearby Renfrew, Bearsden and Paisley. Clydebank sits around 6 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 Clydebank, the survey starts with the wall itself: solid brick, stone or concrete, and whether any old render is sound enough to insulate over.

Approvals in Scotland
In Scotland, permitted development for external wall changes is narrower, so in Clydebank we check with the council's planning team where the appearance changes, and always for flats, tenements and conservation areas.
Where a building warrant is needed for Clydebank work, it's obtained before installation starts, and the quote says who arranges it.
How does external wall insulation work?
Heat moves out through a wall faster when the wall is solid or poorly insulated. EWI wraps the outside face in a continuous layer of insulation, so the masonry stays on the warm side and the cold bridges at floor and party-wall junctions are reduced. The boards are bonded with adhesive and, on most walls, mechanically fixed. A base coat with an embedded glass-fibre mesh goes over the top, then a primer and the decorative finish.
Because the wall itself sits inside the insulation, it stays warmer and drier, and the rooms keep their full size. That is the main difference from internal insulation.

External wall insulation in Clydebank: 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.
