Before we quote in Strabane
Surveys in Strabane also cover the surrounding BT82 district and towns such as Derry~Londonderry and Omagh. It's roughly 17 miles from Strabane to Omagh, the largest town in County Tyrone. Northern Ireland has many rendered and pebble-dashed homes, older solid-walled rural houses, and estates built by the Housing Executive.
Exposure to wind-driven rain varies across County Tyrone: 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.
For homes in Strabane, the survey starts with the wall itself: solid brick, stone or concrete, and whether any old render is sound enough to insulate over.

Permissions in Northern Ireland
In Northern Ireland, permitted development is set by the 2015 Order; in Strabane, changing a house's external appearance, and any work on flats or listed buildings, may need permission, so we check with the council.
Council building control in Northern Ireland checks insulation work of this kind; the quote says how the application is handled.
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 Strabane: 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.
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.
