Aluminium lanterns are strong and slim, but they still rely on gaskets, cappings and seals that wear. Send photos from Finchley (N3) and we'll tell you which it is — with the price agreed in writing before any work.

Worn gaskets
Gaskets do the weatherproofing; they harden and shrink with age.
Thermal movement
Aluminium moves with temperature; seals and fixings take the strain.
About Finchley and the N3 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.
London's extensions are often tight to neighbouring walls and roofs. Where a repair needs access over a neighbour's property, we'll tell you in advance so you can arrange it.

Guide prices for aluminium roof lantern repairs in Finchley
Most aluminium roof lantern repairs jobs come in between £195 and £695 ex VAT (£234–£834 including 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?
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.
