If the room under your lantern overheats in summer or glares, the glass is usually the problem, not the frame. Send photos from Harlow (CM17) and we'll tell you which it is — with the price agreed in writing before any work.
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 Harlow and the CM17 area
Sun and UV do more damage than rain on many lanterns here: brittle ridge caps, chalky finishes and hardened gaskets. They're cheap to replace before they let water in.

Guide prices for solar control and self-cleaning glass upgrades in Harlow
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?
Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in England. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations 2010; we confirm in writing which route applies before any replacement. 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.

Yes. We repair lanterns whoever fitted them. If yours is still under the installer's warranty, contact them first so you don't affect it.

It reduces cleaning on the outer face but still needs rain and occasional rinsing, and the inside still needs cleaning.
