Say Goodbye to Window Condensation

Do you notice condensation on your windows during the winter? You might think condensation on your home’s windows is just a normal part of the cold weather routine, but it certainly doesn’t need to be. Condensation isn’t just an annoyance; it can be damaging to your home, from rotting wood and damaging plaster, to bringing excess moisture into the home.

There are three types of condensation: interior, exterior, and condensation between window panes. Exterior condensation is mostly out of your control, as it has to do with the dew point compared to the window’s temperature, and condensation between window panes will require cleaning the windows or replacing the panes or windows. Let’s focus on interior condensation and how to get to the root of the problem.

Interior condensation is caused by excessive moisture in the home. When warm air from your home reaches cold windows, condensation appears. Condensation can be caused by a slew of factors. Try turning down your humidifier, buying a moisture eliminator, or investing in a dehumidifier. Always use your bathroom and kitchen fans, because activities like showering and cooking can add a lot of moisture to your rooms. Be sure to also run your ceiling fans. In the winter, just make sure they’re running in a clockwise direction (this will ensure warm air sinks). Opening your windows slightly or raising the temperature of the windows with the use of blinds or curtains is another option to get rid of condensation, too.

While it’s true that your daily activities may be adding excess moisture to your home, it’s important to rule out another underlying cause. You’ll want to get to the root of the problem so you can fix it, rather than just trying to treat the symptoms. If you notice condensation on your windows, it may be caused by air leaks. If air is seeping in and out of your home, you’re probably spending excessive amounts on heating and cooling. You can do a few quick tests to determine if air sealing or insulation is needed, including the paper test or the flashlight test.

Weather stripping can help with air leaks, but you’ll want to have your property inspected for air leaks throughout the home. They can be found in places like bath and ceiling fans, electrical access points, can lights, and chimneys. Once gaps, cracks, and leaks are identified, a professional installer will seal leaks with spray foam.
