Homeowners and builders in Penarth come to us for roof lantern installation for a simple reason: honest supply-only prices, made-to-measure fabrication and installation available right across Cardiff.
Free, no-obligation quotes · response within 1 working hour · supply-only or fully installed
Cardiff property here means Victorian terraces and bay-fronted semis where side-return and rear extensions make lanterns a staple. That local context shapes what we recommend in Penarth — from glass specification to frame colour — before a single quote is written.
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.
From Penarth we also serve Llandaff, Whitchurch (Cardiff) and Radyr and the wider county — so if you're comparing quotes anywhere in Cardiff, ours is free, fast and without obligation.
A standard domestic lantern on a ready kerb is a one-day job including sealing and trims. Cut-ins to existing roofs, oversize lanterns or plastered reveals extend that to two days.
A finished kerb to the dimensions we issue, the roof membrane dressed over it, and clear access for glass — which for larger panes can mean two fitters and lifting equipment we bring.
Yes — workmanship is guaranteed in writing, separate from and alongside the lantern manufacturer's product guarantee, so there's no gap between the two.
Yes — our teams cover England, Wales and Scotland. Distance affects scheduling more than price; we'll give you the next available slot for your postcode when you enquire.
We do. Penarth and the surrounding Cardiff towns are core territory for both our installation teams and our supply-only delivery routes.
For Penarth: 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.
