We carry out glazing bar and capping repairs in Amersham and across the HP7 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?

  • A capping visibly higher than its neighbours
  • Rattling or whistling in wind
  • End caps missing at the bottom of a bar

Common causes we find

Gasket shrinkage

Rubber gaskets shrink back from the ends over time, leaving a gap at the ridge or eaves.

Fixings working loose

Screws and clips that hold the capping relax with thermal movement, so the clamp on the glass weakens.

Covering Amersham 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 Amersham as part of Buckinghamshire, about 13 miles from Aylesbury.

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.
