Homeowners and builders in St Austell come to us for bespoke roof lanterns for a simple reason: honest supply-only prices, made-to-measure fabrication and installation available right across Cornwall.
Free, no-obligation quotes · response within 1 working hour · supply-only or fully installed
The Cornwall market is defined by granite cottages and coastal homes where marine-grade aluminium and storm-rated glazing are essential specs — and our St Austell installs reflect that, with specifications matched to the property rather than pulled off a shelf.
Specification doesn't change with postcode: thermally broken frames, 28mm argon-filled glazing, marine-grade powder coating and a 10-year guarantee, whether you buy supply-only for your own builder or book our installation teams.
Our teams cover St Austell alongside Penzance, Camborne and Bodmin and the rest of Cornwall — surveys are free, quotes carry no obligation, and we aim for a response within 1 working hour.
Anything outside a standard rectangular, centre-ridge design — unequal hips, off-centre ridges, three-sided lanterns against walls, linked twin lanterns, unusual pitches or glass specifications. If your drawing doesn't look like a catalogue picture, it's bespoke.
Yes — that's the normal route. Send the roof plan and sections; we return engineered lantern drawings for approval, flag any buildability issues early and fabricate only once everything is signed off.
It depends entirely on what departs from standard. An off-centre ridge adds little; a 7-metre triple-hip lantern with acoustic glass is a different conversation. We price from drawings with no obligation.
Allow 4–8 weeks from approved drawings, longer for unusual glass. We'll commit to a fabrication slot when you approve, so the lantern lands when your build needs it.
We do. St Austell and the surrounding Cornwall towns are core territory for both our installation teams and our supply-only delivery routes.
For St Austell: same-day made-to-measure quotes, standard sizes delivering in around 7–10 working days, and installation slots booked to suit once the survey's done.
Send the form and we’ll come back with honest prices — supply-only or installed — with a response within 1 working hour.
