We carry out glazing bar and capping repairs in Leighton Buzzard and across the LU7 area. Each glazing bar on a roof lantern has a top capping that clamps the glass onto gaskets.

What usually causes it?
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.
Roof lanterns in Leighton Buzzard
Most inland lantern leaks aren't storm damage; they're usually tired sealant, a lifted capping or blocked eaves drainage. All three are quick to find and fix once you know where to look.
Leighton Buzzard is around 17 miles from Bedford, and both are within our Bedfordshire coverage.
If you're just outside Leighton Buzzard, we also cover Dunstable (6 miles), Bletchley (6 miles), Milton Keynes (10 miles).
How much should it cost?
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.

Glazing bar and capping repairs in Leighton Buzzard: questions
Can you repair a lantern someone else installed in Leighton Buzzard?
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 Leighton Buzzard do you cover?
As well as Leighton Buzzard, we cover nearby Dunstable, Bletchley, Milton Keynes, Aylesbury and the rest of Bedfordshire.
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.
