Around Falmouth 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.
Falmouth, Launceston, Helston and Truro and the rest of Cornwall all sit inside standard coverage: free surveys, free quotes, and a response within 1 working hour.
Yes — misting means the sealed unit has failed, not the lantern. We measure the pane, manufacture a matching unit (including self-clean or solar coatings) and fit it in situ, usually within a couple of weeks.
Could be five things: ridge capping, hip junction, perimeter seal, kerb flashing or the flat roof itself, with condensation a sixth impostor. We trace the actual path before quoting, so you pay to fix the real fault.
Yes — repairs cover all major aluminium, uPVC and timber systems regardless of who installed them. Photos of the lantern and the fault speed up the first visit.
The pane itself isn't — once a sealed unit's edge seal fails it's replaced, not resealed. The frame stays; only the glass unit changes.
Yes — Falmouth is inside our standard Cornwall coverage. Our fitting teams survey and install throughout the area, and supply-only deliveries run to Falmouth on dedicated glass transport.
Stocked standard sizes typically deliver to Falmouth within 7–10 working days; made-to-measure fabrication adds to that, and we confirm the slot when you order so it lands with your build programme.
