Before we quote in Alloa
We also cover Stirling and Falkirk, close to Alloa. It's roughly 6 miles from Alloa to Stirling, the largest town in Forth Valley. 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 Alloa 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 Alloa 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 Alloa work, it's obtained before installation starts, and the quote says who arranges it.
Which homes is EWI suited to?
EWI is mainly used on solid-walled houses (most homes built before about 1920), on post-war concrete and steel-framed houses, on homes where cavity fill isn't possible, and on bungalows and park homes. It also suits flats and blocks where the whole building is treated at once.
It is less straightforward where the walls face a pavement with no room to project, on listed buildings, or where planning rules want the existing brick or stone left visible. A survey picks these up before you commit.

External wall insulation in Alloa: 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.
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 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.
