In Amersham, 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.
What you might be seeing
- 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
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.
About Amersham and the HP7 area
Most inland lantern leaks aren't storm damage; they're usually tired sealant, a lifted capping or blocked eaves drainage. All three are quick to find and fix once you know where to look.

Guide prices for solar control and self-cleaning glass upgrades in Amersham
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 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.

How much does it cost to upgrade lantern glass?

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