Free, no-obligation quotes · response within 1 working hour · supply-only or fully installed
Like much of Cumbria, Keswick features slate-and-stone cottages and fell-side farmhouses — wind-load ratings and heritage detailing both matter here. It's the kind of work our surveyors and fitting teams handle week in, week out across the North West 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 Keswick, Workington, Whitehaven and Penrith and every corner of Cumbria. Surveys and quotes are free, with a response within 1 working hour on every enquiry.
Yes — supply-only Korniche orders are dispatched UK-wide with assembly instructions, and our team is on the phone if your builder has questions on the day.
The joint engineering. Korniche components machine together so precisely that the lantern assembles without silicone, external clips or cover caps — which is why installers love it and why the finished lines look so clean.
The frame itself can be assembled on the kerb in under 30 minutes by a competent installer; a full fit including glazing and flashing is comfortably a one-day job. Manufacture lead time is typically one to two weeks.
Yes — the system is fully thermally broken with no metal-to-metal path from outside to inside, and paired with argon-filled units it achieves U-values that comfortably satisfy Building Regulations for extensions.
Yes — installation is available across Keswick and Cumbria, and if you'd rather buy supply-only, kerbside delivery to Keswick is included in our standard service.
Standard-size supply-only prices are on the site now; made-to-measure quotes for Keswick 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.
