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 Canterbury (CT1) 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

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.

Covering Canterbury and nearby

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.

Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.

We cover Canterbury as part of Kent, about 24 miles from Maidstone.

We also cover nearby Whitstable (6 miles), Herne Bay (7 miles), Faversham (9 miles).

What should you expect to pay in Canterbury?

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

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.

Misted glass unit replacement in Canterbury: questions

Can you repair a lantern someone else installed in Canterbury?

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 Canterbury do you cover?

As well as Canterbury, we cover nearby Whitstable, Herne Bay, Faversham, Ashford, Kent and the rest of Kent.

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.
