In Horsham, 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

What you might be seeing

  • 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

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 Horsham and nearby

Sun and UV do more damage than rain on many lanterns here: brittle ridge caps, chalky finishes and hardened gaskets. They're cheap to replace before they let water in.

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.

Horsham is around 25 miles from Chichester, and both are within our West Sussex coverage.

What should you expect to pay in Horsham?

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 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.

Slipped glass panel repairs in Horsham: questions

How do I get a price for slipped glass panel repairs in Horsham?

Send a few photos of the lantern and the problem, with your Horsham postcode. We'll reply with a guide price and tell you whether a visit is needed before we can fix the price.

Do you need to visit to price slipped glass panel repairs?

Not always. Clear photos are often enough for a guide price. Where the cause isn't obvious, a visit to inspect and water-test is charged from £145 ex VAT, confirmed before we come.

What does resetting a slipped panel cost?

Usually £195–£445 ex VAT per panel, confirmed in writing before work starts. If the unit is damaged it may need replacing.

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.
