We carry out cracked lantern glass replacement in Bangor, Down and across the BT19 area. A cracked pane in a roof lantern needs prompt attention because the glass is overhead.
Signs you need cracked lantern glass replacement
- A visible crack in the outer or inner pane
- A starburst from an impact point
- A crack running from an edge (often thermal stress)
What usually causes it?
Impact
Hail, falling branches or dropped tools.
Spontaneous breakage
Toughened glass can occasionally break without warning, which is why laminated inner panes are recommended overhead.
Covering Bangor, Down and nearby
Damp, mild winters keep moss and algae growing on flat roofs and lantern frames, which holds water against seals and blocks weep slots. Regular clearing makes a real difference in wetter areas.
Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.
If you're just outside Bangor, Down, we also cover Newtownards (5 miles), Holywood (6 miles), Carrickfergus (7 miles).
How much should it cost?
Guide price for cracked lantern glass replacement: £295–£795 ex VAT (£354–£954 inc 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 Northern Ireland?
Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in Northern Ireland. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations (Northern Ireland) 2012; we confirm in writing which route applies before any replacement. Listed buildings in Northern Ireland need listed building consent from the council for alterations; check with the council's planning service before changing a lantern on a listed property.
