We carry out slipped glass panel repairs in Hertford and across the SG13 area. 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.

What you might be seeing
- 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
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.
About Hertford and the SG13 area
Leaf fall from garden trees is the most common cause of eaves overflow on suburban extensions. If your lantern sits near trees, clearing the eaves channel each autumn prevents a lot of drips.
Hertford is around 11 miles from St Albans, and both are within our Hertfordshire coverage.
We also cover nearby Hoddesdon (4 miles), Welwyn Garden City (6 miles), Hatfield (7 miles).
How much should it cost?
Most slipped glass panel repairs jobs come in between £195 and £445 ex VAT (£234–£534 including 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.

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.

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