In Letchworth Garden City, as everywhere, aluminium lanterns are strong and slim, but they still rely on gaskets, cappings and seals that wear. Send photos and we'll tell you what we think has failed.

Signs you need aluminium roof lantern repairs

Finish damage
Scratches and chips expose bare metal; coastal air speeds up corrosion.

Typical range: £195–£695 ex VAT, which is £234–£834 with VAT, per lantern. 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?
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.
