We carry out glazing bar and capping repairs in Consett and across the DH8 area. Each glazing bar on a roof lantern has a top capping that clamps the glass onto gaskets.

Is it time for glazing bar and capping repairs?
- A capping visibly higher than its neighbours
- Water running down one glazing bar inside
- Rattling or whistling in wind
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.
About Consett and the DH8 area

Guide prices for glazing bar and capping repairs in Consett
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.
