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 Merseyside

Wind-driven rain is the real test of a roof lantern, and the wetter west sees plenty of it. Leaks that appear only in a storm from one direction usually point to the cappings or eaves on that face — a useful clue when you send us photos.

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 for glazing bar and capping repairs in Merseyside?

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

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?

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.

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.
