Signs you need glazing bar and capping repairs

  • A capping visibly higher than its neighbours
  • Gasket rubber poking out, cracked or missing
  • Rattling or whistling in wind

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 County Antrim

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.

Near the coast, salt in the air is hard on aluminium finishes and fixings; washing the frame occasionally and touching in chips keeps corrosion away.

Do you need permission in Northern Ireland?

In Northern Ireland, 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 (Northern Ireland) 2012, so we set out the route in writing first. Listed buildings in Northern Ireland need listed building consent from the council for alterations; check with the council's planning service before changing a lantern on a listed property.

Glazing bar and capping repairs in County Antrim: 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.

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

Which towns in County Antrim do you cover?

All of County Antrim, including Belfast, Lisburn, Newtownabbey, Carrickfergus, Ballymena, Antrim. Rural and remote addresses are covered by arrangement.
