Aluminium lanterns are strong and slim, but they still rely on gaskets, cappings and seals that wear. Send photos from Thamesmead (SE28) and we'll tell you which it is — with the price agreed in writing before any work.

What you might be seeing
- Cappings lifted or rattling
- Chalky or chipped powder coat
- Corrosion at cut edges or fixings in coastal areas
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.
About Thamesmead and the SE28 area
Even in drier areas, one heavy downpour with blocked eaves is enough to overflow a lantern indoors. Clearing the eaves channel is the simplest prevention there is.
Across London, many lanterns sit on rear extensions with access only through the house, so we protect floors and plan the work to keep time indoors to a minimum. Parking and any permits are factored into the quote.
We cover Thamesmead as part of Greater London, about 11 miles from Westminster.

What should you expect to pay in Thamesmead?
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.
