If you have seen condensation inside the glass of your double glazing there is nothing you can do, the glass needs to be replaced.
The glass is known in the trade as a sealed unit. Which gets shortened to ‘unit.’ A unit can be double or triple-glazed. Home owners will often say ‘my window has misted up.’ The window is the whole part; the glass unit can be replaced without damaging the frame. Most double glazing companies offer the service of replacing units. It is best to call a small independent company. Most towns and cities have small companies that call themselves ‘window doctors.’ You will get a more cost-effective service.
