Roof lanterns in Havant
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.
We cover Havant as part of Hampshire, about 19 miles from Southampton.
Close by, we also cover Waterlooville (3 miles), Portsmouth (6 miles), Gosport (8 miles).
How much should it cost?
Guide price for roof lantern replacement: £1,995–£4,995 ex VAT (£2,394–£5,994 inc 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.

Roof lantern replacement in Havant: questions
Do you need to visit to price roof lantern replacement?
Not always. Clear photos are often enough for a guide price. Where the cause isn't obvious, a visit to inspect and water-test is charged from £145 ex VAT, confirmed before we come.
Can you repair a lantern someone else installed in Havant?
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.
