Porthmadog sits squarely in our Gwynedd coverage area for traditional roof lanterns — which means fast made-to-measure quotes, kerbside delivery for trade and DIY orders, and installation slots with our own teams.
Free, no-obligation quotes · response within 1 working hour · supply-only or fully installed
Like much of Gwynedd, Porthmadog 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 Porthmadog, Bangor, Caernarfon and Pwllheli and every corner of Gwynedd. Surveys and quotes are free, with a response within 1 working hour on every enquiry.

They can — a tall lantern over a new orangery-style extension with brick piers looks superb. On a minimalist flat-roof box, a contemporary low-pitch design is usually the better fit.
We do. Porthmadog and the surrounding Gwynedd towns are core territory for both our installation teams and our supply-only delivery routes.
For Porthmadog: 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.
