In Ystradgynlais, as everywhere, if the room under your lantern overheats in summer or glares, the glass is usually the problem, not the frame. Send photos and we'll tell you what we think has failed.

Bright open-plan living space lit by a large roof lantern with solar control glass

Is it time for solar control and self-cleaning glass upgrades?

  • The room is noticeably hotter than the rest of the house in summer
  • Furniture or flooring fading under the lantern
  • Clear, uncoated glass in an older lantern

Common causes we find

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.

Roof lanterns in Ystradgynlais

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 also cover nearby Neath (7 miles), Ammanford (10 miles), Maesteg (12 miles).

How much should it cost?

Guide price, per glass unit£345–£895 ex VAT£414–£1,074 inc VAT

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.

Solar control and self-cleaning glass upgrades in Ystradgynlais: questions

How do I get a price for solar control and self-cleaning glass upgrades in Ystradgynlais?

Send a few photos of the lantern and the problem, with your Ystradgynlais postcode. We'll reply with a guide price and tell you whether a visit is needed before we can fix the price.

Do you need to visit to price solar control and self-cleaning glass upgrades?

Not always. Clear photos are often enough for a guide price. Where the cause isn't obvious, a visit to inspect and water-test is charged from £145 ex VAT, confirmed before we come.

Can you add a film instead?

Films are cheaper but can affect the unit's warranty and may not suit sloped double glazing. We'd rather replace the unit properly.

Does self-cleaning glass mean no cleaning?

It reduces cleaning on the outer face but still needs rain and occasional rinsing, and the inside still needs cleaning.
