We carry out uPVC roof lantern repairs in Morden and across the SM4 area. Many uPVC roof lanterns have an aluminium core with uPVC cladding and cappings.

What you might be seeing
- Yellowed or brittle end caps
- Cracked cappings or ridge covers
- Leaks at the ridge or eaves
What usually causes it?
UV ageing
uPVC components become brittle and crack after years of sun.
Blocked drainage
As with all lanterns, blocked eaves drainage causes overflow.
Covering Morden 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.
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.
Morden is around 7 miles from Westminster, and both are within our Greater London coverage.
Close by, we also cover Mitcham (1 mile), Wimbledon (2 miles), Carshalton (2 miles).
How much should it cost?
Typical range: £175–£595 ex VAT, which is £210–£714 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?
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.
