Misted Double Glazing Repair in South Wales
Misted or foggy double glazing means the seal between the glass panes has failed, allowing moisture to enter the cavity. This reduces insulation, looks unsightly and can't be cleaned. We replace failed sealed units quickly and affordably — often without changing the frames.
