In Slough, as everywhere, a cracked pane in a roof lantern needs prompt attention because the glass is overhead. Send photos and we'll tell you what we think has failed.
Signs you need cracked lantern glass replacement
- A visible crack in the outer or inner pane
- A crack running from an edge (often thermal stress)
- Broken glass inside the room — keep everyone out of the area
Why it happens
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.

Leaf fall from garden trees is the most common cause of eaves overflow on suburban extensions. If your lantern sits near trees, clearing the eaves channel each autumn prevents a lot of drips.

Guide prices for cracked lantern glass replacement in Slough
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 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.
