Is it time for glazing bar and capping repairs?

  • A capping visibly higher than its neighbours
  • Water running down one glazing bar inside
  • 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.

Do you need permission in Wales?

Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in Wales. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations 2010 (as applied in Wales); we confirm in writing which route applies before any replacement. Listed buildings in Wales need listed building consent from the local planning authority for alterations, with Cadw guidance on historic buildings; check with the council before changing a lantern on a listed property.
