Is Window Condensation A Sign Of Window Problems?
When you shower, you add heat and moisture to the air and when it comes in contact with the colder mirror, condensation accumulates. No issues, just scientific facts here. The same occurs with windows. Here we will explore when window condensation is normal and when it could be a sign of problems.
Interior Window Condensation
Interior window condensation occurs during the winter. As the cold temperatures cause our windows to be cooler, the warm air in the house. This is a sign of a few things… First, it most likely means your windows aren’t drafty, which is a good thing. It also means there is some excess moisture in your home. Excessive moisture can also lead to mold in the home if left unchecked. Showers, cooking, and other factors will raise the humidity for short periods of time also. The moisture will usually evaporate as the sun hits the windows, but you may want to invest in a dehumidifier if the condensation seems excessive. A top rated dehumidifier is the Frigidaire 70-pint Capacity Dehumidifier.
Exterior Window Condensation
Exterior Window Condensation happens in humid climates during the summer. As our air conditioning cools off the temperature in the home, the glass on the windows is cooler. As the hot, humid air comes in contact with the window, moisture begins to build. This usually happens at night. The moisture will dry out as the sun hits the window and warms the glass.
Moisture Between The Panes
This is where our issues really begin! If moisture is accumulating between the panes of your window, then the seal that holds in the argon gas has been broken. Once the seal is broken, the efficiency of the window diminishes. The question then becomes, can this be repaired or is it time to replace the window.
Some questions to ask:
- What is the age of the window?
- Is the condensation only in one pane or multiple panes?
- Is condensation happening in multiple windows?
- Is the window under warranty?
If the window is under warranty (many replacement windows have lifetime warranties), then call your window company.
If interior condensation is only in one or a small number of panes, it can possibly be repaired. Window repair companies will drill a small hole in the glass in a top and bottom corner. They will clean the space then refill the window pane with argon gas and reseal it. This may extend the life of the window so that you don’t have to replace it.
If the windows are your original windows and the moisture is affecting a large portion of the window, it may be time for replacement. Replacement windows have many factors to consider that will help with energy efficiency, moisture control, and temperature transference.
