I have condensation in my windows. Is it time to replace them?


We hear questions about condensation quite often from homeowners during the winter and summer months. Condensation is such a simple thing, literally water vapor, but it is a significant sign of inefficiency in your home and can lead to bigger repair issues down the road.

So, what causes condensation in or on my windows?

Condensation inside or on your windows is normally related to excess humidity or water vapor in the air. Warm air holds more moisture than cold air and when it comes into contact with a colder glass surface, the warm air cools down causing the water vapor to condense into its liquid form. Condensation is more common in the winter and summer months when there are larger differences between the temperatures inside and outside of your home.

All home windows whether new or old will occasionally have condensation from things like cooking and showering. This is very normal and is nothing to be concerned about. However, if condensation is a regular occurrence it can introduce mold and damage your window frames, drywall, paint, or wallpaper resulting in expensive repairs. Regular condensation in or on your windows is also a major sign of energy inefficiency either from air leakage or lack of proper insulation.

Is it time for me to get replacement windows?

If you have regular condensation in your home, it is most likely time to replace your windows. More than just minimizing condensation new replacement windows are very energy efficient and can reduce the temperature difference between the surface of the windows and the air in your home.
