We carry out slipped glass panel repairs in Falmouth and across the TR11 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
- Glass edge overhanging the eaves more than its neighbours
- A leak at the top of one pane only
- A pane that looks out of line with the others
Common causes we find
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 Falmouth and the TR11 area
Western and upland parts of the UK get more rain and more wind-driven rain than the east, and that's what finds weak cappings and blocked eaves first. Lanterns here benefit from a check of the bars on the most exposed face and a clear eaves channel before winter.
Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.
We cover Falmouth as part of Cornwall, about 8 miles from Truro.
Close by, we also cover Truro (8 miles), Redruth (9 miles), Camborne (11 miles).
What should you expect to pay in Falmouth?
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?
Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in England. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations 2010; we confirm in writing which route applies before any replacement. 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.
