In Swindon, as everywhere, each glazing bar on a roof lantern has a top capping that clamps the glass onto gaskets. Send photos and we'll tell you what we think has failed.

What you might be seeing

  • Gasket rubber poking out, cracked or missing
  • Water running down one glazing bar inside
  • 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.

Roof lanterns in Swindon

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.

Close by, we also cover Cirencester (14 miles), Chippenham (16 miles), Witney (20 miles).

How much should it cost?

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?

Most lantern repairs in England need no approval at all. Where a job turns into a replacement, the Building Regulations 2010 apply and we confirm how the work will be signed off before we start. 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 Swindon: questions

Can you repair a lantern someone else installed in Swindon?

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 Swindon do you cover?

As well as Swindon, we cover nearby Cirencester, Chippenham, Witney, Stroud and the rest of Wiltshire.

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.
