We carry out aluminium roof lantern repairs in Seaford and across the BN25 area. Aluminium lanterns are strong and slim, but they still rely on gaskets, cappings and seals that wear.

Signs you need aluminium roof lantern repairs
- Leaks at bars or ridge
- Misted units
- Corrosion at cut edges or fixings in coastal areas
Why it happens
Worn gaskets
Gaskets do the weatherproofing; they harden and shrink with age.
Thermal movement
Aluminium moves with temperature; seals and fixings take the strain.
Covering Seaford and nearby
Sun and UV do more damage than rain on many lanterns here: brittle ridge caps, chalky finishes and hardened gaskets. They're cheap to replace before they let water in.
Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.
We cover Seaford as part of East Sussex, about 11 miles from Brighton.
If you're just outside Seaford, we also cover Eastbourne (8 miles), Hailsham (9 miles), Brighton (11 miles).
What should you expect to pay in Seaford?
Guide price for aluminium roof lantern repairs: £195–£695 ex VAT (£234–£834 inc 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.
