In Welshpool, 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

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

What usually causes it?

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 Welshpool 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 Welshpool as part of Powys, about 12 miles from Newtown.

Close by, we also cover Newtown (12 miles), Wrexham (28 miles), Machynlleth (30 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.

Not necessarily — blocks can crush and stops can break over time — but if the lantern is new, talk to the installer first as it may be under warranty.
