We carry out solar control and self-cleaning glass upgrades in Seaham and across the SR7 area. If the room under your lantern overheats in summer or glares, the glass is usually the problem, not the frame.

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

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

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.

No ventilation

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

Roof lanterns in Seaham

Snow and ice sitting at the eaves can block a lantern's drainage and push water back under the glass as it melts. If your lantern leaks after a thaw rather than after rain, tell us — it points to the eaves and kerb.

From Durham to Seaham is roughly 10 miles — all part of the County Durham area we cover.

How much should it cost?

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

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.

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

Can you repair a lantern someone else installed in Seaham?

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.

Which places near Seaham do you cover?

As well as Seaham, we cover nearby Houghton-le-Spring, Sunderland, Peterlee, Washington and the rest of County Durham.

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.
