Each glazing bar on a roof lantern has a top capping that clamps the glass onto gaskets. Send photos from Westhoughton (BL5) and we'll tell you which it is — with the price agreed in writing before any work.
What you might be seeing
- A capping visibly higher than its neighbours
- Gasket rubber poking out, cracked or missing
- End caps missing at the bottom of a bar
What usually causes it?
Fixings working loose
Screws and clips that hold the capping relax with thermal movement, so the clamp on the glass weakens.
Damage
Ladders, window cleaning or someone stepping on a lantern can bend a capping or unclip it.
Roof lanterns in Westhoughton
Wind-driven rain is the real test of a roof lantern, and the wetter west sees plenty of it. Leaks that appear only in a storm from one direction usually point to the cappings or eaves on that face — a useful clue when you send us photos.
In built-up areas, access is often the hardest part of the job — through the house, over a neighbour's roof, or with parking restrictions. We plan access in advance and price any tower or scaffold into the quote.
We cover Westhoughton as part of Greater Manchester, about 13 miles from Manchester.
If you're just outside Westhoughton, we also cover Atherton (2 miles), Hindley (3 miles), Tyldesley (3 miles).
How much should it cost?
Typical range: £165–£395 ex VAT, which is £198–£474 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?
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.

Glazing bar and capping repairs in Westhoughton: questions
Can you repair a lantern someone else installed in Westhoughton?
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.
Which places near Westhoughton do you cover?
As well as Westhoughton, we cover nearby Atherton, Hindley, Tyldesley, Leigh and the rest of Greater Manchester.
How much do capping and gasket repairs cost?
Usually £165–£395 ex VAT per lantern depending on how many bars are affected, confirmed in writing before work starts.
Can a capping just be clipped back on?
Sometimes, if nothing underneath has failed. We check the gaskets first, because clipping a capping over a perished gasket doesn't stop the leak.
