We carry out solar control and self-cleaning glass upgrades in Antrim and across the BT41 area. If the room under your lantern overheats in summer or glares, the glass is usually the problem, not the frame.

What you might be seeing
- The room is noticeably hotter than the rest of the house in summer
- Glare on screens or worktops
- Clear, uncoated glass in an older lantern
Why it happens
Clear or standard Low-E glass
Standard units let a lot of solar heat through; solar control coatings reflect more of it.
Orientation
South- and west-facing lanterns gain the most heat in the afternoon.
About Antrim and the BT41 area
Damp, mild winters keep moss and algae growing on flat roofs and lantern frames, which holds water against seals and blocks weep slots. Regular clearing makes a real difference in wetter areas.
Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.
From Belfast to Antrim is roughly 13 miles — all part of the County Antrim area we cover.

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 Northern Ireland?
In Northern Ireland, 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 (Northern Ireland) 2012, so we set out the route in writing first. Listed buildings in Northern Ireland need listed building consent from the council for alterations; check with the council's planning service before changing a lantern on a listed property.

Solar control and self-cleaning glass upgrades in Antrim: questions
How do I get a price for solar control and self-cleaning glass upgrades in Antrim?
Send a few photos of the lantern and the problem, with your Antrim 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.
