In Grantham, 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
  • Furniture or flooring fading under the lantern

Common causes we find

Orientation

South- and west-facing lanterns gain the most heat in the afternoon.

No ventilation

A lantern without opening vents traps warm air at ceiling level.

Roof lanterns in Grantham

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.

Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.

What should you expect to pay in Grantham?

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

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.

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.
