We carry out glazing bar and capping repairs in Hamilton and across the ML3 area. Each glazing bar on a roof lantern has a top capping that clamps the glass onto gaskets.
What you might be seeing
- 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
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 Hamilton and the ML3 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.
If you're just outside Hamilton, we also cover Motherwell (2 miles), Bellshill (4 miles), Wishaw (5 miles).
Guide prices for glazing bar and capping repairs in Hamilton
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 Scotland?
Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in Scotland. Replacing the whole lantern or enlarging the opening is different and falls under the Building (Scotland) Regulations 2004; we confirm in writing which route applies before any replacement. Listed buildings in Scotland need listed building consent from the planning authority for alterations, with Historic Environment Scotland guidance; check before changing a lantern on a listed property.
