Signs you need glazing bar and capping repairs

  • A capping visibly higher than its neighbours
  • Water running down one glazing bar inside
  • End caps missing at the bottom of a bar

What usually causes it?

Gasket shrinkage

Rubber gaskets shrink back from the ends over time, leaving a gap at the ridge or eaves.

Fixings working loose

Screws and clips that hold the capping relax with thermal movement, so the clamp on the glass weakens.

Roof lanterns in Lanarkshire

Damp, mild winters keep moss and algae growing on flat roofs and lantern frames, which holds water against seals and blocks weep slots. Regular clearing makes a real difference in wetter areas.

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.

Glazing bar and capping repairs in Lanarkshire: questions

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.

Which towns in Lanarkshire do you cover?

All of Lanarkshire, including Hamilton, East Kilbride, Cumbernauld, Coatbridge, Airdrie, Motherwell. Rural and remote addresses are covered by arrangement.
