Free, no-obligation quotes · response within 1 working hour · supply-only or fully installed
Gwynedd property here means slate-built terraces and Snowdonia farmhouses — exposure ratings and slate-grey frames are popular. That local context shapes what we recommend in Caernarfon — 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 Caernarfon we also serve Porthmadog, Pwllheli and Dolgellau and the wider county — so if you're comparing quotes anywhere in Gwynedd, ours is free, fast and without obligation.
uPVC if budget leads — it's the most affordable route to a quality lantern. Aluminium if sightlines and colour matter most. Structurally they share the same engineered ridge, so neither compromises on strength.
Up to 4 metres, which covers almost every domestic extension. That means no horizontal bars crossing the ceiling void — just clean glass to the ridge.
Yes — it's built on Ultraframe's Classic roof platform, one of the most-installed conservatory and lantern roof systems in the UK, with decades of structural track record.
28mm double-glazed units as standard, with self-clean coatings and blue or neutral solar control available. We'll match the glass to the room's orientation.
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.
