From Caernarfon kitchen extensions to full orangery builds, our self-cleaning glass roof lanterns service covers supply-only delivery and complete installation throughout Gwynedd — same product, your choice of who fits it.
Free, no-obligation quotes · response within 1 working hour · supply-only or fully installed
Like much of Gwynedd, Caernarfon features slate-built terraces and Snowdonia farmhouses — exposure ratings and slate-grey frames are popular. It's the kind of work our surveyors and fitting teams handle week in, week out across the Wales region.
You get the same product either way — thermally broken aluminium, self-clean and solar-control glass options, made to the millimetre. The only choice is who fits it: your builder with our documentation, or our own nationwide teams.
Coverage takes in Caernarfon, Bangor, Porthmadog and Pwllheli and every corner of Gwynedd. Surveys and quotes are free, with a response within 1 working hour on every enquiry.
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.
Usually — if your frame takes standard sealed units we can manufacture self-clean replacements to size and fit them in situ, upgrading the glass without touching the structure.
Yes — installation is available across Caernarfon and Gwynedd, and if you'd rather buy supply-only, kerbside delivery to Caernarfon is included in our standard service.
Standard-size supply-only prices are on the site now; made-to-measure quotes for Caernarfon 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.
