Signs you need cracked lantern glass replacement

  • A starburst from an impact point
  • A crack running from an edge (often thermal stress)
  • Broken glass inside the room — keep everyone out of the area

Why it happens

Thermal stress

Uneven heating across a pane, edge damage or partial shading can crack glass from the edge.

Spontaneous breakage

Toughened glass can occasionally break without warning, which is why laminated inner panes are recommended overhead.

How much should it cost?

Guide price, per glass unit£295–£795 ex VAT£354–£954 inc VAT

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 England?

Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in England. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations 2010; we confirm in writing which route applies before any replacement. Listed buildings need listed building consent from the local council for alterations, and conservation areas can have extra controls; like-for-like repairs are treated differently from changes, so check with the council's conservation officer first.
