Welwyn Garden City sits squarely in our Hertfordshire coverage area for korniche roof lanterns — which means fast made-to-measure quotes, kerbside delivery for trade and DIY orders, and installation slots with our own teams.
Free, no-obligation quotes · response within 1 working hour · supply-only or fully installed
Like much of Hertfordshire, Welwyn Garden City features garden-city housing, 1930s semis and a fast-moving extension market across the commuter towns. It's the kind of work our surveyors and fitting teams handle week in, week out across the East of England 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 Welwyn Garden City, St Albans, Hemel Hempstead and Stevenage and every corner of Hertfordshire. Surveys and quotes are free, with a response within 1 working hour on every enquiry.
Every Korniche is made to order, so 'custom' is the standard. You give us the external kerb size and the lantern arrives fabricated to those exact dimensions.
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.
We do. Welwyn Garden City and the surrounding Hertfordshire towns are core territory for both our installation teams and our supply-only delivery routes.
For Welwyn Garden City: same-day made-to-measure quotes, standard sizes delivering in around 7–10 working days, and installation slots booked to suit once the survey's done.
Send the form and we’ll come back with honest prices — supply-only or installed — with a response within 1 working hour.
