A cracked pane in a roof lantern needs prompt attention because the glass is overhead. Send photos from Morden (SM4) and we'll tell you which it is — with the price agreed in writing before any work.

Signs you need cracked lantern glass replacement
- A visible crack in the outer or inner pane
- A starburst from an impact point

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.

London's extensions are often tight to neighbouring walls and roofs. Where a repair needs access over a neighbour's property, we'll tell you in advance so you can arrange it.

Guide prices for cracked lantern glass replacement in Morden

Do you need permission in England?
In England, like-for-like repairs to a roof lantern don't usually involve building control. A full replacement or a bigger opening is controlled under the Building Regulations 2010, so we set out the route in writing first. 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.
