We carry out slipped glass panel repairs in Caerphilly and across the CF83 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.

Signs you need slipped glass panel repairs

  • 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

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.

Loose cappings

If the capping no longer clamps the glass firmly, the unit can creep with thermal movement.

Covering Caerphilly and nearby

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.

We cover Caerphilly as part of Gwent, about 9 miles from Newport, Gwent.

Close by, we also cover Risca (6 miles), Pontypridd (6 miles), Blackwood (6 miles).

How much should it cost?

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 Wales?

Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in Wales. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations 2010 (as applied in Wales); we confirm in writing which route applies before any replacement. Listed buildings in Wales need listed building consent from the local planning authority for alterations, with Cadw guidance on historic buildings; check with the council before changing a lantern on a listed property.
