Free, no-obligation quotes · response within 1 working hour · supply-only or fully installed
Around Gainsborough and the wider county, housing stock runs to wide rural plots, brick farmhouses and coastal bungalows — large single lanterns and multiple-lantern roofs both feature. We've specified and supplied for exactly these property types across Lincolnshire, so recommendations come from real local precedent.
Every lantern is thermally broken aluminium as standard, glazed with 28mm argon-filled units, and available with self-clean and solar-control coatings. Supply-only orders include kerb specifications and fitting documentation; installed projects carry our written workmanship guarantee on top of the 10-year product cover.
Gainsborough, Louth, Sleaford and Lincoln and the rest of Lincolnshire all sit inside standard coverage: free surveys, free quotes, and a response within 1 working hour.
Standard sizes below — made to measure quoted same day. Installation available nationwide if you’d rather we fit it.

On current systems, around 40mm at the ridge externally. Claims much below that usually measure a different part of the frame — we'll always quote like-for-like ridge and hip dimensions so you can compare honestly.
No — the slimness comes from structural bonding and better alloys, not thinner-for-the-sake-of-it metal. Each lantern is engineered for its span and site wind loading.
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 Gainsborough and Lincolnshire, and if you'd rather buy supply-only, kerbside delivery to Gainsborough is included in our standard service.
