Whether it's a single lantern over a Cromer kitchen or a multi-roof development, our opening & vented roof lanterns service pairs supply-only pricing with nationwide installation — and Norfolk is core territory for both.
Free, no-obligation quotes · response within 1 working hour · supply-only or fully installed
The Norfolk market is defined by flint cottages, barn conversions and big-sky rural plots — lanterns suit both contemporary builds and conservation-sensitive conversions — and our Cromer installs reflect that, with specifications matched to the property rather than pulled off a shelf.
Specification doesn't change with postcode: thermally broken frames, 28mm argon-filled glazing, marine-grade powder coating and a 10-year guarantee, whether you buy supply-only for your own builder or book our installation teams.
Our teams cover Cromer alongside Wymondham, North Walsham and Diss and the rest of Norfolk — surveys are free, quotes carry no obligation, and we aim for a response within 1 working hour.
Not in a quality system — the sash closes onto continuous gaskets and locks down tight. The vent panes carry the same glazing spec and guarantee as the fixed glass around them.
Over kitchens and in south-facing rooms, emphatically yes — venting at the highest point purges heat and steam faster than any window can. In cooler, well-ventilated rooms a fixed lantern plus good doors often suffices.
The rain sensor closes it automatically — it's a standard part of the package, not an optional extra, so an open vent and a surprise shower never meet.
Only on certain systems — vents are normally factory-built into the roof slope. Send photos of your lantern and we'll confirm whether a retrofit sash exists for it or whether replacement is the honest answer.
Yes — installation is available across Cromer and Norfolk, and if you'd rather buy supply-only, kerbside delivery to Cromer is included in our standard service.
Standard-size supply-only prices are on the site now; made-to-measure quotes for Cromer usually come back the same working day, and installed projects are priced after a free survey.
Send the form and we’ll come back with honest prices — supply-only or installed — with a response within 1 working hour.
