Around Johnstone and the wider county, housing stock runs to tenement flats and suburban semis with steady rear-extension demand. We've specified and supplied for exactly these property types across Renfrewshire, 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.
Johnstone, Erskine, Bridge of Weir and Paisley and the rest of Renfrewshire all sit inside standard coverage: free surveys, free quotes, and a response within 1 working hour.
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.
It depends entirely on what departs from standard. An off-centre ridge adds little; a 7-metre triple-hip lantern with acoustic glass is a different conversation. We price from drawings with no obligation.
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.
Yes — Johnstone is inside our standard Renfrewshire coverage. Our fitting teams survey and install throughout the area, and supply-only deliveries run to Johnstone on dedicated glass transport.
Stocked standard sizes typically deliver to Johnstone 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.
