In Farnham, 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.

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
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.
Orientation
South- and west-facing lanterns gain the most heat in the afternoon.
Covering Farnham and nearby
Even in drier areas, one heavy downpour with blocked eaves is enough to overflow a lantern indoors. Clearing the eaves channel is the simplest prevention there is.

Guide prices for solar control and self-cleaning glass upgrades in Farnham
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?
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 Farnham: 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.
Which places near Farnham do you cover?
As well as Farnham, we cover nearby Aldershot, Fleet, Farnborough, Bordon and the rest of Surrey.
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.
Does self-cleaning glass mean no cleaning?
It reduces cleaning on the outer face but still needs rain and occasional rinsing, and the inside still needs cleaning.
