Property across Cornwall runs to granite cottages and coastal homes where marine-grade aluminium and storm-rated glazing are essential specs — context that genuinely changes what we specify, from glazing coatings to frame colours and fixing details.
Frames are thermally broken aluminium, glazing is 28mm argon-filled with self-clean and solar options, and everything is made to measure. Buy supply-only with kerbside delivery, or have our fitters handle the lot under a written workmanship guarantee.
Yes — repairs cover all major aluminium, uPVC and timber systems regardless of who installed them. Photos of the lantern and the fault speed up the first visit.
The pane itself isn't — once a sealed unit's edge seal fails it's replaced, not resealed. The frame stays; only the glass unit changes.
When the frame itself has failed: non-thermally-broken early aluminium running with condensation, or softwood gone soft. We'll tell you straight on survey and price both routes.
Yes — misting means the sealed unit has failed, not the lantern. We measure the pane, manufacture a matching unit (including self-clean or solar coatings) and fit it in situ, usually within a couple of weeks.
Send the form and we’ll come back with honest prices — supply-only or installed — with a response within 1 working hour.
