In St Albans, as everywhere, 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 and we'll tell you what we think has failed.

Signs you need roof lantern replacement
- Several misted or cracked units
- Rotten timber throughout
- Repeated leaks after previous repairs
Common causes we find
Age
Older lanterns can't be brought up to modern performance with repairs alone.
Structural damage
Impact or movement distorts the frame.
Covering St Albans and nearby
Lanterns in central England see a bit of everything — summer sun that ages seals and end caps, autumn leaf fall that blocks eaves, and frosty mornings that bring condensation. A yearly check covers all three.
If you're just outside St Albans, we also cover Harpenden (5 miles), Hatfield (5 miles), Hemel Hempstead (5 miles).
Guide prices for roof lantern replacement in St Albans
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?
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 St Albans: 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.
Which places near St Albans do you cover?
As well as St Albans, we cover nearby Harpenden, Hatfield, Hemel Hempstead, Welwyn Garden City and the rest of Hertfordshire.
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.
