A cracked pane in a roof lantern needs prompt attention because the glass is overhead. Send photos from Thornaby-on-Tees (TS17) and we'll tell you which it is — with the price agreed in writing before any work.

Roof lanterns in Thornaby-on-Tees
Snow and ice sitting at the eaves can block a lantern's drainage and push water back under the glass as it melts. If your lantern leaks after a thaw rather than after rain, tell us — it points to the eaves and kerb.

What should you expect to pay in Thornaby-on-Tees?
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.
