Free, no-obligation quotes · response within 1 working hour · supply-only or fully installed
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.
