If the room under your lantern overheats in summer or glares, the glass is usually the problem, not the frame. Send photos from Hounslow (TW3) and we'll tell you which it is — with the price agreed in writing before any work.

What you might be seeing
- Glare on screens or worktops
- Furniture or flooring fading under the lantern
- 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.
About Hounslow and the TW3 area
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.
Across London, many lanterns sit on rear extensions with access only through the house, so we protect floors and plan the work to keep time indoors to a minimum. Parking and any permits are factored into the quote.
We cover Hounslow as part of Greater London, about 10 miles from Westminster.
Close by, we also cover Isleworth (1 mile), Heston (1 mile), Richmond (2 miles).
Guide prices for solar control and self-cleaning glass upgrades in Hounslow
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.
