We carry out glazing bar and capping repairs in Wood Green and across the N22 area. Each glazing bar on a roof lantern has a top capping that clamps the glass onto gaskets.
Signs you need glazing bar and capping repairs
- A capping visibly higher than its neighbours
- Water running down one glazing bar inside
- 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 Wood Green
Even in drier areas, one heavy downpour with blocked eaves is enough to overflow a lantern indoors. Clearing the eaves channel is the simplest prevention there is.
Across London, many lanterns sit on rear extensions with access only through the house, so we protect floors and plan the work to keep time indoors to a minimum. Parking and any permits are factored into the quote.
From Westminster to Wood Green is roughly 7 miles — all part of the Greater London area we cover.

Guide prices for glazing bar and capping repairs in Wood Green
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 Wood Green: questions
Can you repair a lantern someone else installed in Wood Green?
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 Wood Green do you cover?
As well as Wood Green, we cover nearby Muswell Hill, Tottenham, Archway, Stamford Hill and the rest of Greater London.
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.
