Homeowners and builders in Dolgellau come to us for self-cleaning glass roof lanterns 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
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 Dolgellau — 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 Dolgellau we also serve Caernarfon, Porthmadog and Pwllheli and the wider county — so if you're comparing quotes anywhere in Gwynedd, ours is free, fast and without obligation.
The self-clean layer itself is virtually invisible. Any tint you see comes from the solar-control side of the unit — blue is the popular choice, neutral keeps the glass colour-true.
Yes, within honest limits. Daylight breaks down organic dirt and rain rinses it off in sheets, so the glass stays presentably clean with almost no intervention. Heavy bird soiling or long droughts still occasionally want a hose.
No — it's pyrolytic, fired into the glass surface during manufacture rather than applied afterwards, so it lasts the life of the unit with nothing to renew.
That's the standard pairing — one sealed unit with the self-clean layer outside and the solar-control coating within. Most lantern glass we supply ships exactly that way.
We do. Dolgellau and the surrounding Gwynedd towns are core territory for both our installation teams and our supply-only delivery routes.
For Dolgellau: 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.
