A cracked pane in a roof lantern needs prompt attention because the glass is overhead. Send photos from Haverfordwest (SA61) and we'll tell you which it is — with the price agreed in writing before any work.
Is it time for cracked lantern glass replacement?
- A starburst from an impact point

Thermal stress
Uneven heating across a pane, edge damage or partial shading can crack glass from the edge.
Roof lanterns in Haverfordwest
Wind-driven rain is the real test of a roof lantern, and the wetter west sees plenty of it. Leaks that appear only in a storm from one direction usually point to the cappings or eaves on that face — a useful clue when you send us photos.
Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.
We cover Haverfordwest as part of Dyfed, about 29 miles from Carmarthen.
Neighbouring places we cover include Milford Haven (7 miles), Pembroke Dock (8 miles), Cardigan (23 miles).
How much should it cost?
Typical range: £295–£795 ex VAT, which is £354–£954 with VAT, per glass unit. Towers or scaffold, where needed, are priced into the quote. Your fixed price is confirmed in writing before any work starts.
Do you need permission in Wales?
Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in Wales. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations 2010 (as applied in Wales); we confirm in writing which route applies before any replacement. Listed buildings in Wales need listed building consent from the local planning authority for alterations, with Cadw guidance on historic buildings; check with the council before changing a lantern on a listed property.
