In Greenford, as everywhere, 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 and we'll tell you what we think has failed.

What you might be seeing

  • One pane looks hazier than the others
  • Misting that comes and goes with the weather
  • Water marks or tide lines inside the unit

What usually causes it?

Edge seal failure

Every sealed unit has an edge seal and desiccant. Once the seal fails, humid air gets in and the desiccant saturates.

Water sitting on the edge

If the unit's edge sits in water because the eaves don't drain, the seal fails sooner.

Roof lanterns in Greenford

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.

Guide price, per glass unit£245–£595 ex VAT£294–£714 inc VAT

Most misted glass unit replacement jobs come in between £245 and £595 ex VAT (£294–£714 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?

In England, 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 Regulations 2010, so we set out the route in writing first. 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.

How long does a replacement unit take?
