Another busy week of replacement glass installations. It seems the sun shines and shows that the glass isn’t in need of a clean, but it’s a failed unit.

Contrary to popular belief, failed double-glazing units aren’t just common – they’re pretty much guaranteed! You might feel as if you’ve been dealt a bum hand when your own units blow, but in reality it’s largely inevitable. After all, there isn’t a double-glazed unit on the face of the Earth that’s designed to last for all eternity, meaning that sooner or later, they’re going to let you down.
