Carmarthenshire property here means rural farmhouses and market-town stock with steady conversion and extension demand. That local context shapes what we recommend in Carmarthen — 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 Carmarthen we also serve Ammanford, Llandeilo and Llandovery and the wider county — so if you're comparing quotes anywhere in Carmarthenshire, ours is free, fast and without obligation.

A timber kerb at least 150mm above the finished roof surface, built to the lantern's external footprint. We issue exact dimensions at order so it's ready before the lantern arrives.
Yes — installation is available across Carmarthen and Carmarthenshire, and if you'd rather buy supply-only, kerbside delivery to Carmarthen is included in our standard service.
