Each glazing bar on a roof lantern has a top capping that clamps the glass onto gaskets. Send photos from Skelmersdale (WN8) and we'll tell you which it is — with the price agreed in writing before any work.

Is it time for glazing bar and capping repairs?
- A capping visibly higher than its neighbours
- Gasket rubber poking out, cracked or missing
- Water running down one glazing bar inside
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 Skelmersdale
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.
Skelmersdale is around 15 miles from Preston, and both are within our Lancashire coverage.
If you're just outside Skelmersdale, we also cover Ormskirk (5 miles), Wigan (6 miles), Kirkby (7 miles).
How much should it cost?
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.

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.

Yes. Timber lanterns use different beads and cappings, and we repair those as part of timber lantern repairs.
