We carry out cracked lantern glass replacement in Sunbury-on-Thames and across the TW16 area. A cracked pane in a roof lantern needs prompt attention because the glass is overhead.

What you might be seeing
- 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?
Most cracked lantern glass replacement jobs come in between £295 and £795 ex VAT (£354–£954 including 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?
Most lantern repairs in England need no approval at all. Where a job turns into a replacement, the Building Regulations 2010 apply and we confirm how the work will be signed off before we start. 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.
