In Chesham, 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.

What you might be seeing
- Leaks at bars or ridge
- Cappings lifted or rattling
- Misted units
What usually causes it?
Worn gaskets
Gaskets do the weatherproofing; they harden and shrink with age.
Finish damage
Scratches and chips expose bare metal; coastal air speeds up corrosion.
Covering Chesham and nearby
Lanterns in central England see a bit of everything — summer sun that ages seals and end caps, autumn leaf fall that blocks eaves, and frosty mornings that bring condensation. A yearly check covers all three.
Chesham is around 12 miles from Aylesbury, and both are within our Buckinghamshire coverage.
Neighbouring places we cover include Amersham (2 miles), Berkhamsted (4 miles), Chalfont St Peter (7 miles).
What should you expect to pay in Chesham?
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.
