If the room under your lantern overheats in summer or glares, the glass is usually the problem, not the frame. We carry out solar control and self-cleaning glass upgrades across Gwent, with a guide price from your photos and a fixed price in writing before any work starts.

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.
Roof lanterns in Gwent
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.
What should you expect to pay for solar control and self-cleaning glass upgrades in Gwent?
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?
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 Gwent: questions
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.
Which towns in Gwent do you cover?
All of Gwent, including Newport, Gwent, Cwmbran, Pontypool, Ebbw Vale, Caerphilly, Risca. Rural and remote addresses are covered by arrangement.
