Condensation on your windows is a sign of poor insulation quality on your windows!

One of the most annoying side effects of winter is the condensation of steam on your windows. If you don’t prepare for it, it can become a cause for concern and, in the long run, the start of many other problems in your daily life.

Condensation on your windows, what to expect? 

Condensation on windows can seriously damage your home. Condensation can rot wood moldings and damage plaster. If there is excess humidity in your home, it can cause interior condensation and therefore can damage your entire home, especially the areas around windows.

Condensation inside, outside or between the panes

Excessive humidity in the home can cause interior window condensation. This most often happens in winter because of the warm air in the house settling on the cold windows.

Exterior condensation from windows is simply dew and occurs when the window is cooler than the dew point.

On the other hand, this is our point of importance, the condensation between the panes is very often due to a rupture of the seal between the panes or to a desiccator that no longer works very well.



If humid air enters the house around a particular window, that moisture will first collect on the glass in that window. If this is your case, you will need to check for air leaks around the window and call a professional to reseal or replace it, depending on the severity of the condition.

The appearance of condensation on your glass indicates that the windows are not doing their job properly

Unfortunately, if there is condensation between the panes, you will need to replace the glass units. This may or may not be possible depending on the type, age and manufacturer of the original window.

How about replacing the whole window?

In some cases, you will not be able to replace the glass units and you will need to replace the entire window. This is generally a good idea, especially if the windows are old. Great advances have been made in window technology over the years, and replacing the entire window can have additional benefits as well.
