In Windsor, 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.

Bright open-plan living space lit by a large roof lantern with solar control glass

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.

Roof lanterns in Windsor

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 Windsor

Guide price, per glass unit£345–£895 ex VAT£414–£1,074 inc VAT

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 England?

Most lantern repairs in England need no approval at all. Where a job turns into a replacement, the Building Regulations 2010 apply and we confirm how the work will be signed off before we start. 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.

Solar control and self-cleaning glass upgrades in Windsor: questions

How do I get a price for solar control and self-cleaning glass upgrades in Windsor?

Send a few photos of the lantern and the problem, with your Windsor postcode. We'll reply with a guide price and tell you whether a visit is needed before we can fix the price.

Can you repair a lantern someone else installed in Windsor?

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.

How much does it cost to upgrade lantern glass?

Usually £345–£895 ex VAT per unit depending on size and specification, confirmed in writing before work starts.

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.
