Free, no-obligation quotes · response within 1 working hour · supply-only or fully installed
Like much of Carmarthenshire, Carmarthen features rural farmhouses and market-town stock with steady conversion and extension demand. 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 Carmarthen, Llanelli, Ammanford and Llandeilo and every corner of Carmarthenshire. Surveys and quotes are free, with a response within 1 working hour on every enquiry.
Standard sizes below — made to measure quoted same day. Installation available nationwide if you’d rather we fit it.

Tighter tolerances, structural glazing and higher-spec profiles all add manufacturing cost, and installation needs more care. It's the premium tier of the lantern market and priced accordingly.
Very much so — they're a favourite on architect-designed projects. We work from your drawings, check kerb dimensions before fabrication and coordinate delivery with your build programme.
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.
