For roof lantern replacement in Cornwall, we offer both routes: supply-only with delivery for builders and DIYers, and full installation by our own teams in Truro, Falmouth, St Austell and county-wide.
Free, no-obligation quotes · response within 1 working hour · supply-only or fully installed
Property across Cornwall runs to granite cottages and coastal homes where marine-grade aluminium and storm-rated glazing are essential specs — context that genuinely changes what we specify, from glazing coatings to frame colours and fixing details.
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.
We remove and dispose of it as part of the installation — the price we quote includes taking the old unit away.
Usually, yes. If the kerb is sound and square we fabricate to its exact external size; if it's tired or an odd footprint we fit adapter sections or rebuild the timber as part of the job.
Very. Domes sit on the same style of kerb a lantern needs, so a swap to a modern glazed lantern is typically a one-day changeover that also transforms how the room looks and holds heat.
Minimal — the work happens at roof level. Inside, expect the reveal to need a trim or touch of decoration; the room is usable again the same evening.
Send the form and we’ll come back with honest prices — supply-only or installed — with a response within 1 working hour.
