We carry out misted glass unit replacement in Bodmin and across the PL31 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.

Signs you need misted glass unit replacement

  • Fog, droplets or white bloom between the panes
  • One pane looks hazier than the others
  • 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.

Water sitting on the edge

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

About Bodmin and the PL31 area

Damp, mild winters keep moss and algae growing on flat roofs and lantern frames, which holds water against seals and blocks weep slots. Regular clearing makes a real difference in wetter areas.

Near the coast, salt in the air is hard on aluminium finishes and fixings; washing the frame occasionally and touching in chips keeps corrosion away.

Bodmin is around 20 miles from Truro, and both are within our Cornwall coverage.

Guide prices for misted glass unit replacement in Bodmin

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

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 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.
