We carry out uPVC roof lantern repairs in Walthamstow and across the E17 area. Many uPVC roof lanterns have an aluminium core with uPVC cladding and cappings.

What you might be seeing
- Yellowed or brittle end caps
- Green algae along the bars
- Rattling or whistling in wind
Common causes we find
Clip failure
Clip-on cappings can lose their grip and lift.
Blocked drainage
As with all lanterns, blocked eaves drainage causes overflow.
Covering Walthamstow and nearby
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.
From Westminster to Walthamstow is roughly 8 miles — all part of the Greater London area we cover.

Guide prices for uPVC roof lantern repairs in Walthamstow
Most uPVC roof lantern repairs jobs come in between £175 and £595 ex VAT (£210–£714 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?
Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in England. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations 2010; we confirm in writing which route applies before any replacement. 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.
