Homeowners and builders in Pwllheli come to us for opening & vented 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 Pwllheli — 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 Pwllheli we also serve Caernarfon, Porthmadog and Dolgellau and the wider county — so if you're comparing quotes anywhere in Gwynedd, ours is free, fast and without obligation.
Over kitchens and in south-facing rooms, emphatically yes — venting at the highest point purges heat and steam faster than any window can. In cooler, well-ventilated rooms a fixed lantern plus good doors often suffices.
The rain sensor closes it automatically — it's a standard part of the package, not an optional extra, so an open vent and a surprise shower never meet.
Only on certain systems — vents are normally factory-built into the roof slope. Send photos of your lantern and we'll confirm whether a retrofit sash exists for it or whether replacement is the honest answer.
Your choice: a simple wall switch, a remote, app control, or full automation that opens on temperature and closes on rain. Most kitchens land on switch-plus-rain-sensor.
We do. Pwllheli and the surrounding Gwynedd towns are core territory for both our installation teams and our supply-only delivery routes.
For Pwllheli: 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.
