Like much of Durham, Seaham features colliery terraces and stone market towns with growing extension and conversion demand. It's the kind of work our surveyors and fitting teams handle week in, week out across the North East 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 Seaham, Durham, Darlington and Hartlepool and every corner of Durham. Surveys and quotes are free, with a response within 1 working hour on every enquiry.
Allow 4–8 weeks from approved drawings, longer for unusual glass. We'll commit to a fabrication slot when you approve, so the lantern lands when your build needs it.
Often, yes — shifting the ridge or splitting one large lantern into two smaller ones around the structure is a common bespoke solution. Send the structural drawings and we'll propose options.
Anything outside a standard rectangular, centre-ridge design — unequal hips, off-centre ridges, three-sided lanterns against walls, linked twin lanterns, unusual pitches or glass specifications. If your drawing doesn't look like a catalogue picture, it's bespoke.
Yes — that's the normal route. Send the roof plan and sections; we return engineered lantern drawings for approval, flag any buildability issues early and fabricate only once everything is signed off.
Yes — Seaham is inside our standard Durham coverage. Our fitting teams survey and install throughout the area, and supply-only deliveries run to Seaham on dedicated glass transport.
Stocked standard sizes typically deliver to Seaham within 7–10 working days; made-to-measure fabrication adds to that, and we confirm the slot when you order so it lands with your build programme.
Send the form and we’ll come back with honest prices — supply-only or installed — with a response within 1 working hour.
