We carry out misted glass unit replacement in Antrim and across the BT41 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

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.

Covering Antrim and nearby

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.

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