We carry out glazing bar and capping repairs in Fulham and across the SW6 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
- Rattling or whistling in wind
Why it happens
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 Fulham
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.
London's extensions are often tight to neighbouring walls and roofs. Where a repair needs access over a neighbour's property, we'll tell you in advance so you can arrange it.
Fulham is around 3 miles from Westminster, and both are within our Greater London coverage.
If you're just outside Fulham, we also cover Chelsea (1 mile), Putney (2 miles), Battersea (2 miles).
Guide prices for glazing bar and capping repairs in Fulham
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?
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.

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.
