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. Send photos from Cambuslang (G72) and we'll tell you which it is — with the price agreed in writing before any work.
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.
Covering Cambuslang and nearby
Western and upland parts of the UK get more rain and more wind-driven rain than the east, and that's what finds weak cappings and blocked eaves first. Lanterns here benefit from a check of the bars on the most exposed face and a clear eaves channel before winter.
From Hamilton to Cambuslang is roughly 6 miles — all part of the Lanarkshire area we cover.
We also cover nearby Rutherglen (2 miles), East Kilbride (3 miles), Glasgow (5 miles).
What should you expect to pay in Cambuslang?
Guide price for misted glass unit replacement: £245–£595 ex VAT (£294–£714 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 Scotland?
In Scotland, 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 (Scotland) Regulations 2004, so we set out the route in writing first. Listed buildings in Scotland need listed building consent from the planning authority for alterations, with Historic Environment Scotland guidance; check before changing a lantern on a listed property.

Misted glass unit replacement in Cambuslang: questions
How do I get a price for misted glass unit replacement in Cambuslang?
Send a few photos of the lantern and the problem, with your Cambuslang postcode. We'll reply with a guide price and tell you whether a visit is needed before we can fix the price.
Do you need to visit to price misted glass unit replacement?
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.
How long does a replacement unit take?
Units are made to measure, so there's a lead time between measuring and fitting. Fitting itself is usually a short visit.
Will the new pane match the others?
We match tint and coatings as closely as possible; a new unit can look very slightly clearer than older neighbours.
