Signs you need solar control and self-cleaning glass upgrades

  • The room is noticeably hotter than the rest of the house in summer
  • Glare on screens or worktops
  • Furniture or flooring fading under the lantern

What usually causes it?

Clear or standard Low-E glass

Standard units let a lot of solar heat through; solar control coatings reflect more of it.

No ventilation

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

Covering Llantwit Major 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.

Most solar control and self-cleaning glass upgrades jobs come in between £345 and £895 ex VAT (£414–£1,074 including 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?

In Wales, like-for-like repairs to a roof lantern don't usually involve building control. A full replacement or a bigger opening is controlled under the Building Regulations 2010 (as applied in Wales), so we set out the route in writing first. 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 Llantwit Major: questions

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

Send a few photos of the lantern and the problem, with your Llantwit Major 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.
