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 Downpatrick (BT30) and we'll tell you which it is — with the price agreed in writing before any work.

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.

Movement and age

Thermal movement and age wear the seal; units at the bottom of the lantern often go first.

Covering Downpatrick and nearby

Wind-driven rain is the real test of a roof lantern, and the wetter west sees plenty of it. Leaks that appear only in a storm from one direction usually point to the cappings or eaves on that face — a useful clue when you send us photos.

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.

Misted glass unit replacement in Downpatrick: questions

Do you cover Downpatrick?

Yes. We cover Downpatrick, including the BT30 postcode area, as part of County Down. Send photos by WhatsApp or the form for a free guide price, and we'll confirm the fixed price in writing before any work starts.

Can you repair a lantern someone else installed in Downpatrick?

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.

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.
