If you’ve noticed condensation inside your double glazing, a cloudy appearance, or your windows have become foggy between the panes, your sealed unit has most likely failed. This is commonly referred to as blown double glazing, misted double glazing, or a failed sealed unit. Because the moisture is trapped inside the insulated glass, no amount of cleaning will remove it from the inside of the window.
The good news is that in most cases, your window frame doesn’t need replacing. We simply replace the failed double glazed glass unit with a brand new, made-to-measure sealed unit, restoring crystal clear views, improving thermal efficiency and giving your windows a new lease of life. Every replacement glass unit is backed by our 10-year anti-fog guarantee, so you can enjoy complete peace of mind for years to come.
