Why Do My Windows Have Condensation on the Inside?

9/1/2014 6:57:00 PM

Have you ever wondered why condensation forms on your windows and what you can do to prevent this from happening?

Window condensation occurs through a combination of the moisture in the air and the temperature. Often, window condensation is nothing to be concerned about, as it occurs naturally when extreme temperature differences exist between the interior and exterior of your home or if the air outside the home is very moist. Glass is a water barrier, so when humid or extreme weather conditions exist, window condensation naturally occurs.

People commonly blame the window for condensation buildup, but most often the buildup of window condensation results from high humidity in your home. Humidity can build up as a result of showers, dishwashers, washing machines, humidifiers and even breathing. In fact, a family of four can add as much as a quart of moisture to the air per hour!

If you have concerns about the moisture levels inside your home, contact a heating or cooling specialist in your area for assistance.

Broken Window Seals

Although window condensation is most often caused by excess humidity in the home, it can occur from window failure as well. If you have multi-paned windows with insulating gas and notice condensation on your windows, you could have a problem—especially if the condensation has formed between the panes of glass. This is indicative of seal failure and requires the window to be replaced if you wish to retain the energy saving benefits of multi-pane insulating windows. The window will still look and function properly—although with moisture present on occasion—it just will have lost its insulating properties.

Unfortunately, once a window has leaked its insulating gas from the window, it cannot be repaired and the window will need to be replaced. Depending on the age of the window, and the manufacturer, this may be covered by your window warranty.
