We carry out misted glass unit replacement in Blairgowrie and across the PH10 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.

What you might be seeing

  • Fog, droplets or white bloom between the panes
  • One pane looks hazier than the others
  • Misting that comes and goes with the weather

Why it happens

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.

Snow and ice sitting at the eaves can block a lantern's drainage and push water back under the glass as it melts. If your lantern leaks after a thaw rather than after rain, tell us — it points to the eaves and kerb.

Guide prices for misted glass unit replacement in Blairgowrie

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 Scotland?

Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in Scotland. Replacing the whole lantern or enlarging the opening is different and falls under the Building (Scotland) Regulations 2004; we confirm in writing which route applies before any replacement. Listed buildings in Scotland need listed building consent from the planning authority for alterations, with Historic Environment Scotland guidance; check before changing a lantern on a listed property.

Misted glass unit replacement in Blairgowrie: questions

Do you need to visit to price misted glass unit replacement?

Not always. Clear photos are often enough for a guide price. Where the cause isn't obvious, a visit to inspect and water-test is charged from £145 ex VAT, confirmed before we come.

Can you repair a lantern someone else installed in Blairgowrie?

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.
