If the room under your lantern overheats in summer or glares, the glass is usually the problem, not the frame. Send photos from Barnet (EN5) and we'll tell you which it is — with the price agreed in writing before any work.

What usually causes it?
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.

Drier, sunnier parts of the UK are kinder to seals than the wet west, but strong sun ages sealant, gaskets and plastic end caps, and south- or west-facing lanterns can make rooms very warm. Solar control glass and an opening vent help.
London's extensions are often tight to neighbouring walls and roofs. Where a repair needs access over a neighbour's property, we'll tell you in advance so you can arrange it.
Barnet is around 11 miles from Westminster, and both are within our Greater London coverage.

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

Solar control and self-cleaning glass upgrades in Barnet: questions
Do you need to visit to price solar control and self-cleaning glass upgrades?
Not always. Clear photos are often enough for a guide price. Where the cause isn't obvious, a visit to inspect and water-test is charged from £145 ex VAT, confirmed before we come.
Can you repair a lantern someone else installed in Barnet?
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.
