Homeowners and builders in Caernarfon come to us for roof lantern replacement for a simple reason: honest supply-only prices, made-to-measure fabrication and installation available right across Gwynedd.
Free, no-obligation quotes · response within 1 working hour · supply-only or fully installed
The Gwynedd market is defined by slate-built terraces and Snowdonia farmhouses — exposure ratings and slate-grey frames are popular — and our Caernarfon 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 Caernarfon alongside Dolgellau, Bangor and Porthmadog and the rest of Gwynedd — surveys are free, quotes carry no obligation, and we aim for a response within 1 working hour.
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.
We do. Caernarfon and the surrounding Gwynedd towns are core territory for both our installation teams and our supply-only delivery routes.
For Caernarfon: 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.
