Signs you need glazing bar and capping repairs

  • Gasket rubber poking out, cracked or missing
  • Water running down one glazing bar inside
  • Rattling or whistling in wind

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.

Covering Tonbridge and nearby

Drier, sunnier parts of the UK are kinder to seals than the wet west, but strong sun ages sealant, gaskets and plastic end caps, and south- or west-facing lanterns can make rooms very warm. Solar control glass and an opening vent help.

Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.

Tonbridge is around 12 miles from Maidstone, and both are within our Kent coverage.

What should you expect to pay in Tonbridge?

Guide price, per lantern£165–£395 ex VAT£198–£474 inc VAT

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?

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.

Glazing bar and capping repairs in Tonbridge: questions

How do I get a price for glazing bar and capping repairs in Tonbridge?

Send a few photos of the lantern and the problem, with your Tonbridge postcode. We'll reply with a guide price and tell you whether a visit is needed before we can fix the price.

Can you repair a lantern someone else installed in Tonbridge?

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.

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.

Do you repair uPVC and timber lantern bars too?

Yes. Timber lanterns use different beads and cappings, and we repair those as part of timber lantern repairs.
