Each glazing bar on a roof lantern has a top capping that clamps the glass onto gaskets. Send photos from Gloucester (GL1) and we'll tell you which it is — with the price agreed in writing before any work.
Signs you need glazing bar and capping repairs
- A capping visibly higher than its neighbours
- Rattling or whistling in wind
- End caps missing at the bottom of a bar
Common causes we find
Gasket shrinkage
Rubber gaskets shrink back from the ends over time, leaving a gap at the ridge or eaves.
Fixings working loose
Screws and clips that hold the capping relax with thermal movement, so the clamp on the glass weakens.
About Gloucester and the GL1 area
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.
Neighbouring places we cover include Cheltenham (7 miles), Stroud (8 miles), Tewkesbury (9 miles).
What should you expect to pay in Gloucester?
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?
Most lantern repairs in England need no approval at all. Where a job turns into a replacement, the Building Regulations 2010 apply and we confirm how the work will be signed off before we start. 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 Gloucester: questions
How do I get a price for glazing bar and capping repairs in Gloucester?
Send a few photos of the lantern and the problem, with your Gloucester postcode. We'll reply with a guide price and tell you whether a visit is needed before we can fix the price.
Which places near Gloucester do you cover?
As well as Gloucester, we cover nearby Cheltenham, Stroud, Tewkesbury, Ledbury and the rest of Gloucestershire.
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.
