Roof lanterns in Purley
Sun and UV do more damage than rain on many lanterns here: brittle ridge caps, chalky finishes and hardened gaskets. They're cheap to replace before they let water in.
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.
Purley is around 11 miles from Westminster, and both are within our Greater London coverage.
If you're just outside Purley, we also cover Coulsdon (2 miles), South Croydon (2 miles), Wallington (3 miles).
Guide prices for roof lantern replacement in Purley
Most roof lantern replacement jobs come in between £1,995 and £4,995 ex VAT (£2,394–£5,994 including VAT), supplied and fitted. 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.

Can you repair a lantern someone else installed in Purley?
Yes. We repair lanterns whoever fitted them. If yours is still under the installer's warranty, contact them first so you don't affect it.
Can the new lantern use the existing opening?
Usually, if the kerb is sound and the size suits a standard or made-to-measure lantern.
Will you tell me if repair is enough?
Yes. We'd rather do a repair that works than sell a lantern you don't need.
