What usually causes it?

Orientation

South- and west-facing lanterns gain the most heat in the afternoon.

No ventilation

A lantern without opening vents traps warm air at ceiling level.

Covering Penarth 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.

Penarth is around 3 miles from Cardiff, and both are within our South Glamorgan coverage.

We also cover nearby Cardiff (3 miles), Barry (5 miles), Caerphilly (10 miles).

How much should it cost?

Guide price for solar control and self-cleaning glass upgrades: £345–£895 ex VAT (£414–£1,074 inc VAT), per glass unit. 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.
