Each glazing bar on a roof lantern has a top capping that clamps the glass onto gaskets. Send photos from Gosport (PO12) 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

- 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.
Damage
Ladders, window cleaning or someone stepping on a lantern can bend a capping or unclip it.

How much should it cost?
Guide price for glazing bar and capping repairs: £165–£395 ex VAT (£198–£474 inc 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 Gosport: questions
Do you cover Gosport?

Which places near Gosport do you cover?
As well as Gosport, we cover nearby Portsmouth, Fareham, Ryde, Waterlooville and the rest of Hampshire.
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.
