Around Truro and the wider county, housing stock runs to granite cottages and coastal homes where marine-grade aluminium and storm-rated glazing are essential specs. We've specified and supplied for exactly these property types across Cornwall, so recommendations come from real local precedent.
Every lantern is thermally broken aluminium as standard, glazed with 28mm argon-filled units, and available with self-clean and solar-control coatings. Supply-only orders include kerb specifications and fitting documentation; installed projects carry our written workmanship guarantee on top of the 10-year product cover.
Truro, Launceston, Helston and Falmouth and the rest of Cornwall all sit inside standard coverage: free surveys, free quotes, and a response within 1 working hour.

Yes — installation is available across Truro and Cornwall, and if you'd rather buy supply-only, kerbside delivery to Truro is included in our standard service.
