In Heswall, 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.

Is it time for 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
What usually causes it?
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.
About Heswall and the CH60 area
Western and upland parts of the UK get more rain and more wind-driven rain than the east, and that's what finds weak cappings and blocked eaves first. Lanterns here benefit from a check of the bars on the most exposed face and a clear eaves channel before winter.
Urban grime and traffic film dull glass and frames quickly; a clean and seal check makes a tired lantern look and perform much better.
Near the coast, salt in the air is hard on aluminium finishes and fixings; washing the frame occasionally and touching in chips keeps corrosion away.
Heswall is around 8 miles from Liverpool, and both are within our Merseyside coverage.
If you're just outside Heswall, we also cover Bebington (4 miles), Birkenhead (6 miles), Wallasey (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 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.
