In Darlington, as everywhere, many uPVC roof lanterns have an aluminium core with uPVC cladding and cappings. Send photos and we'll tell you what we think has failed.

Signs you need uPVC roof lantern repairs
- Yellowed or brittle end caps

Why it happens
Clip failure
Clip-on cappings can lose their grip and lift.
Blocked drainage
As with all lanterns, blocked eaves drainage causes overflow.
Covering Darlington and nearby
Colder winters mean more frosty mornings, and a roof lantern is often the coldest surface in a warm kitchen — so condensation is as common as genuine leaks. We check which you've got before quoting.
We cover Darlington as part of County Durham, about 17 miles from Durham.
Close by, we also cover Newton Aycliffe (7 miles), Stockton-on-Tees (10 miles), Thornaby-on-Tees (10 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?
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.
