Each glazing bar on a roof lantern has a top capping that clamps the glass onto gaskets. Send photos from Widnes (WA8) and we'll tell you which it is — with the price agreed in writing before any work.
Is it time for glazing bar and capping repairs?
- A capping visibly higher than its neighbours
- Gasket rubber poking out, cracked or missing
- Water running down one glazing bar inside
Common causes we find
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 Widnes
Damp, mild winters keep moss and algae growing on flat roofs and lantern frames, which holds water against seals and blocks weep slots. Regular clearing makes a real difference in wetter areas.
Widnes is around 14 miles from Chester, and both are within our Cheshire coverage.

How much should it cost?
Most glazing bar and capping repairs jobs come in between £165 and £395 ex VAT (£198–£474 including 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 Widnes: questions
How do I get a price for glazing bar and capping repairs in Widnes?
Send a few photos of the lantern and the problem, with your Widnes postcode. We'll reply with a guide price and tell you whether a visit is needed before we can fix the price.
Do you need to visit to price glazing bar and capping repairs?
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 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.
Do you repair uPVC and timber lantern bars too?
Yes. Timber lanterns use different beads and cappings, and we repair those as part of timber lantern repairs.
