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 Loughton (IG10) and we'll tell you which it is — with the price agreed in writing before any work.
Is it time for misted glass unit replacement?
- One pane looks hazier than the others
- Misting that comes and goes with the weather
- Water marks or tide lines inside the unit
Why it happens
Water sitting on the edge
If the unit's edge sits in water because the eaves don't drain, the seal fails sooner.
Movement and age
Thermal movement and age wear the seal; units at the bottom of the lantern often go first.

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.

Guide prices for misted glass unit replacement in Loughton
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?
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.

Misted glass unit replacement in Loughton: questions
Can you repair a lantern someone else installed in Loughton?
Yes. We repair lanterns whoever fitted them. If yours is still under the installer's warranty, contact them first so you don't affect it.
Which places near Loughton do you cover?
As well as Loughton, we cover nearby Chingford, Woodford Green, Waltham Abbey, Cheshunt and the rest of Essex.
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.
