Roof lantern glass panel slipped down past the eaves leaving a gap beneath the glazing bar

Is it time for slipped glass panel repairs?

  • A visible gap under the capping at the top of a pane
  • Glass edge overhanging the eaves more than its neighbours
  • A pane that looks out of line with the others

Why it happens

Missing setting blocks

Blocks under the bottom edge carry the weight of the unit; if they're missing or crushed, the unit creeps down.

Failed glass stops

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

Covering Cardiff and nearby

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.

We also cover nearby Penarth (3 miles), Caerphilly (7 miles), Barry (7 miles).

What should you expect to pay in Cardiff?

Guide price, per panel£195–£445 ex VAT£234–£534 inc VAT

Typical range: £195–£445 ex VAT, which is £234–£534 with VAT, per panel. 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 Wales?

Most lantern repairs in Wales need no approval at all. Where a job turns into a replacement, the Building Regulations 2010 (as applied in Wales) apply and we confirm how the work will be signed off before we start. 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.

Which places near Cardiff do you cover?

Can a slipped panel be pushed back up?

Not safely without removing the capping. The fix is to support the unit properly so it can't slip again.

Does a slipped panel mean my lantern was badly fitted?

Not necessarily — blocks can crush and stops can break over time — but if the lantern is new, talk to the installer first as it may be under warranty.
