We carry out solar control and self-cleaning glass upgrades in Thatcham and across the RG18 area. If the room under your lantern overheats in summer or glares, the glass is usually the problem, not the frame.

Is it time for 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
- Clear, uncoated glass in an older lantern
Common causes we find
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.
About Thatcham and the RG18 area
Leaf fall from garden trees is the most common cause of eaves overflow on suburban extensions. If your lantern sits near trees, clearing the eaves channel each autumn prevents a lot of drips.
From Reading to Thatcham is roughly 13 miles — all part of the Berkshire area we cover.

How much should it cost?
Typical range: £345–£895 ex VAT, which is £414–£1,074 with 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 England?
In England, 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, so we set out the route in writing first. Listed buildings need listed building consent from the local council for alterations, and conservation areas can have extra controls; like-for-like repairs are treated differently from changes, so check with the council's conservation officer first.
