We carry out misted glass unit replacement in Edmonton and across the N18 area. If a roof lantern pane looks cloudy or wet between the two layers of glass, the sealed unit has failed and moisture has got inside.

What you might be seeing
- Fog, droplets or white bloom between the panes
- Misting that comes and goes with the weather
- Water marks or tide lines inside the unit
Common causes we find
Edge seal failure
Every sealed unit has an edge seal and desiccant. Once the seal fails, humid air gets in and the desiccant saturates.
Movement and age
Thermal movement and age wear the seal; units at the bottom of the lantern often go first.
About Edmonton and the N18 area
Sun and UV do more damage than rain on many lanterns here: brittle ridge caps, chalky finishes and hardened gaskets. They're cheap to replace before they let water in.
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.
We cover Edmonton as part of Greater London, about 9 miles from Westminster.
Close by, we also cover Tottenham (2 miles), Enfield (2 miles), Chingford (3 miles).
What should you expect to pay in Edmonton?
Typical range: £245–£595 ex VAT, which is £294–£714 with 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.
