In Slough, 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.

Signs you need 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
Missing setting blocks
Blocks under the bottom edge carry the weight of the unit; if they're missing or crushed, the unit creeps down.
Loose cappings
If the capping no longer clamps the glass firmly, the unit can creep with thermal movement.
Roof lanterns in Slough
Most inland lantern leaks aren't storm damage; they're usually tired sealant, a lifted capping or blocked eaves drainage. All three are quick to find and fix once you know where to look.
Slough is around 17 miles from Reading, and both are within our Berkshire coverage.
We also cover nearby Windsor (2 miles), Maidenhead (5 miles), Gerrards Cross (6 miles).
How much should it cost?
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.
