Each glazing bar on a roof lantern has a top capping that clamps the glass onto gaskets. Send photos from Bootle (L20) and we'll tell you which it is — with the price agreed in writing before any work.
Signs you need 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
Why it happens
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.
About Bootle and the L20 area
Western and upland parts of the UK get more rain and more wind-driven rain than the east, and that's what finds weak cappings and blocked eaves first. Lanterns here benefit from a check of the bars on the most exposed face and a clear eaves channel before winter.
Urban grime and traffic film dull glass and frames quickly; a clean and seal check makes a tired lantern look and perform much better.
Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.

What should you expect to pay in Bootle?
Most glazing bar and capping repairs jobs come in between £165 and £395 ex VAT (£198–£474 including 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?
In England, like-for-like repairs to a roof lantern don't usually involve building control. A full replacement or a bigger opening is controlled under the Building Regulations 2010, so we set out the route in writing first. 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 Bootle: questions
How do I get a price for glazing bar and capping repairs in Bootle?
Send a few photos of the lantern and the problem, with your Bootle postcode. We'll reply with a guide price and tell you whether a visit is needed before we can fix the price.
Which places near Bootle do you cover?
As well as Bootle, we cover nearby Litherland, Wallasey, Liverpool, Maghull and the rest of Merseyside.
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.
