Each glazing bar on a roof lantern has a top capping that clamps the glass onto gaskets. Send photos from Rayleigh (SS6) 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
- 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.
About Rayleigh and the SS6 area
Drier, sunnier parts of the UK are kinder to seals than the wet west, but strong sun ages sealant, gaskets and plastic end caps, and south- or west-facing lanterns can make rooms very warm. Solar control glass and an opening vent help.
We cover Rayleigh as part of Essex, about 12 miles from Chelmsford.
We also cover nearby South Benfleet (3 miles), Wickford (4 miles), Canvey Island (5 miles).
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 Rayleigh: questions
How do I get a price for glazing bar and capping repairs in Rayleigh?
Send a few photos of the lantern and the problem, with your Rayleigh 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 Rayleigh do you cover?
As well as Rayleigh, we cover nearby South Benfleet, Wickford, Canvey Island, Southend-on-Sea and the rest of Essex.
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.
