Whether it's a single lantern over a Helston kitchen or a multi-roof development, our roof lantern replacement service pairs supply-only pricing with nationwide installation — and Cornwall is core territory for both.
Free, no-obligation quotes · response within 1 working hour · supply-only or fully installed
Cornwall property here means granite cottages and coastal homes where marine-grade aluminium and storm-rated glazing are essential specs. That local context shapes what we recommend in Helston — from glass specification to frame colour — before a single quote is written.
Frames are thermally broken aluminium, glazing is 28mm argon-filled with self-clean and solar options, and everything is made to measure. Buy supply-only with kerbside delivery, or have our fitters handle the lot under a written workmanship guarantee.
From Helston we also serve Launceston, Truro and Falmouth and the wider county — so if you're comparing quotes anywhere in Cornwall, ours is free, fast and without obligation.
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.
If it's single-glazed, non-thermally-broken or streaming with condensation, the comfort and energy gains are substantial. We'll be honest on survey if yours has life left in it.
We remove and dispose of it as part of the installation — the price we quote includes taking the old unit away.
Yes — installation is available across Helston and Cornwall, and if you'd rather buy supply-only, kerbside delivery to Helston is included in our standard service.
Standard-size supply-only prices are on the site now; made-to-measure quotes for Helston usually come back the same working day, and installed projects are priced after a free survey.
Send the form and we’ll come back with honest prices — supply-only or installed — with a response within 1 working hour.
