In Stevenage, as everywhere, a slipped panel is a glass unit that has slid down its glazing bars, leaving a gap at the top and often pushing past the eaves at the bottom. Send photos and we'll tell you what we think has failed.

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

Signs you need 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

Common causes we find

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 Stevenage and nearby

Lanterns in central England see a bit of everything — summer sun that ages seals and end caps, autumn leaf fall that blocks eaves, and frosty mornings that bring condensation. A yearly check covers all three.

We cover Stevenage as part of Hertfordshire, about 12 miles from St Albans.

Close by, we also cover Hitchin (5 miles), Letchworth Garden City (5 miles), Welwyn Garden City (7 miles).

How much should it cost?

Guide price for slipped glass panel repairs: £195–£445 ex VAT (£234–£534 inc 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 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.
