How do you confirm a sealed unit has blown before you quote?
The main giveaway is misting or condensation between the panes that won’t wipe away from either side. You might also notice a milky tidemark on the glass or moisture building up inside the unit.
In most cases, that points to the sealed unit failing rather than the window frame itself.
Measure it up, send us the sizes and we’ll price up the replacement unit.
