Glazing bar and capping repairs in Greenwich

Dealing with a lifted capping or perished gasket in Greenwich (SE10)? We re-seat or replace lifted cappings, perished gaskets and loose glazing bar fixings, with a fixed price agreed in writing first.

We carry out glazing bar and capping repairs in Greenwich and across the SE10 area. Each glazing bar on a roof lantern has a top capping that clamps the glass onto gaskets.

What you might be seeing

  • Water running down one glazing bar inside
  • Rattling or whistling in wind
  • End caps missing at the bottom of a bar

Common causes we find

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 Greenwich

Sun and UV do more damage than rain on many lanterns here: brittle ridge caps, chalky finishes and hardened gaskets. They're cheap to replace before they let water in.

Across London, many lanterns sit on rear extensions with access only through the house, so we protect floors and plan the work to keep time indoors to a minimum. Parking and any permits are factored into the quote.

We cover Greenwich as part of Greater London, about 6 miles from Westminster.

We also cover nearby Blackheath (1 mile), Canary Wharf (2 miles), Catford (2 miles).

How much should it cost?

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?

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 Greenwich: questions

Do you cover Greenwich?

Yes. We cover Greenwich, including the SE10 postcode area, as part of Greater London. Send photos by WhatsApp or the form for a free guide price, and we'll confirm the fixed price in writing before any work starts.

Which places near Greenwich do you cover?

As well as Greenwich, we cover nearby Blackheath, Canary Wharf, Catford, Peckham and the rest of Greater London.

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.
