In Retford, 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

  • A capping visibly higher than its neighbours
  • Gasket rubber poking out, cracked or missing
  • End caps missing at the bottom of a bar

Why it happens

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 Retford and nearby

Leaf fall from garden trees is the most common cause of eaves overflow on suburban extensions. If your lantern sits near trees, clearing the eaves channel each autumn prevents a lot of drips.

We cover Retford as part of Nottinghamshire, about 27 miles from Nottingham.

Guide prices for glazing bar and capping repairs in Retford

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

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.

Glazing bar and capping repairs in Retford: questions

Can you repair a lantern someone else installed in Retford?

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 Retford do you cover?

As well as Retford, we cover nearby Worksop, Gainsborough, Doncaster, Mansfield and the rest of Nottinghamshire.

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.
