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.
Standard sizes below — made to measure quoted same day. Installation available nationwide if you’d rather we fit it.

Yes — Caernarfon is inside our standard Gwynedd coverage. Our fitting teams survey and install throughout the area, and supply-only deliveries run to Caernarfon on dedicated glass transport.
