Around Llandaff and the wider county, housing stock runs to Victorian terraces and bay-fronted semis where side-return and rear extensions make lanterns a staple. We've specified and supplied for exactly these property types across Cardiff, 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.
Llandaff, Whitchurch (Cardiff), Radyr and Cardiff and the rest of Cardiff all sit inside standard coverage: free surveys, free quotes, and a response within 1 working hour.
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.
Yes — Llandaff is inside our standard Cardiff coverage. Our fitting teams survey and install throughout the area, and supply-only deliveries run to Llandaff on dedicated glass transport.
