Local considerations in Stirling
We also cover Alloa and Falkirk, close to Stirling. East Central Scotland mixes stone tenements and terraces with post-war council housing and harled bungalows and semis.
Exposure to wind-driven rain varies across Forth Valley: 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 Stirling around the details that cause trouble later — cills, eaves, downpipes and the base of the wall above the damp-proof course.

Approvals in Scotland
In Scotland, permitted development for external wall changes is narrower, so in Stirling we check with the council's planning team where the appearance changes, and always for flats, tenements and conservation areas.
Scotland's building standards cover changes to external wall construction; we check whether your job in Stirling needs a warrant.
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 Stirling: 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.
