We're repair-first, but some lanterns are past it: distorted frames, rot through the main bars, or most of the glass failed. Send photos from Sunderland (SR1) and we'll tell you which it is — with the price agreed in writing before any work.

Is it time for roof lantern replacement?
- Distorted or sagging frame
- Rotten timber throughout
- Repeated leaks after previous repairs
Why it happens
Age
Older lanterns can't be brought up to modern performance with repairs alone.
Structural damage
Impact or movement distorts the frame.
Roof lanterns in Sunderland
Freeze-thaw cycles open up tired sealant and gaskets faster than mild weather does. A spring check after a hard winter catches most problems before they leak.
Urban grime and traffic film dull glass and frames quickly; a clean and seal check makes a tired lantern look and perform much better.

Guide prices for roof lantern replacement in Sunderland
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?
In England, like-for-like repairs to a roof lantern don't usually involve building control. A full replacement or a bigger opening is controlled under the Building Regulations 2010, so we set out the route in writing first. 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 Sunderland: 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 Sunderland?
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.
