Free, no-obligation quotes · response within 1 working hour · supply-only or fully installed
Around Radyr 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.
Radyr, Llandaff, Whitchurch (Cardiff) and Cardiff and the rest of Cardiff all sit inside standard coverage: free surveys, free quotes, and a response within 1 working hour.
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.
Could be five things: ridge capping, hip junction, perimeter seal, kerb flashing or the flat roof itself, with condensation a sixth impostor. We trace the actual path before quoting, so you pay to fix the real fault.
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.
Yes — installation is available across Radyr and Cardiff, and if you'd rather buy supply-only, kerbside delivery to Radyr is included in our standard service.
Standard-size supply-only prices are on the site now; made-to-measure quotes for Radyr 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.
