How long does sealed unit replacement take?
In most cases, replacing a sealed unit takes around 30–90 minutes per window. However, this can vary depending on a number of factors, such as the size and type of glass, how accessible the window is, and the condition of the existing frame.

What causes misted double glazing?
While condensation on the outside of your windows shows your double glazing is working properly, misting inside the glass panes is a sign of a problem.
Misted double glazing is caused by a failed window seal, which allows moisture to enter between the panes. This leads to condensation that cannot be wiped away.
Once the seal has failed, the only effective solution is to replace the glass unit. Replacing a failed double glazing unit is a cost-effective way to restore clear, energy-efficient windows.
