If the room under your lantern overheats in summer or glares, the glass is usually the problem, not the frame. Send photos from Streatham (SW16) and we'll tell you which it is — with the price agreed in writing before any work.
Signs you need solar control and self-cleaning glass upgrades
- The room is noticeably hotter than the rest of the house in summer
- Furniture or flooring fading under the lantern
- Clear, uncoated glass in an older 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.
About Streatham and the SW16 area
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.
Streatham is around 5 miles from Westminster, and both are within our Greater London coverage.

What should you expect to pay in Streatham?
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?
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.
