We carry out glazing bar and capping repairs in Reigate and across the RH2 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?
- Gasket rubber poking out, cracked or missing
- Rattling or whistling in wind
- 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.
Covering Reigate and nearby
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.
Reigate is around 16 miles from Guildford, and both are within our Surrey coverage.
We also cover nearby Redhill (2 miles), Horley (5 miles), Banstead (6 miles).
Guide prices for glazing bar and capping repairs in Reigate
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?
Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in England. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations 2010; we confirm in writing which route applies before any replacement. 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.

Sometimes, if nothing underneath has failed. We check the gaskets first, because clipping a capping over a perished gasket doesn't stop the leak.
