Is it time for slipped glass panel repairs?

  • A visible gap under the capping at the top of a pane
  • A leak at the top of one pane only
  • A pane that looks out of line with the others

Common causes we find

Failed glass stops

Many systems use an end stop at the eaves. If it's missing or broken, nothing holds the glass in place.

Loose cappings

If the capping no longer clamps the glass firmly, the unit can creep with thermal movement.

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 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.
