What’s Causing Condensation Inside Your Windows and What to Do About It

Noticing fog or water droplets forming between or on the inside of your windows? You’re not alone. Window condensation is a common issue, especially during chilly Washington winters and damp spring mornings. While it might just seem like an annoying nuisance, it can also signal bigger issues, like poor insulation, excess indoor humidity, or even failing window seals. When you need window repair or replacement in Spokane, Washington, give the experts at Five Mile Glass a call first.
Why Is There Water on the Inside of My Windows?
Whenever moist, warm air in your home comes into contact with a cooler surface, such as the glass of your window, condensation occurs. Moisture in the air condenses into liquid due to the temperature difference. It's especially common in bathrooms, kitchens, and other humid areas.
What It Could Mean
If condensation is happening between the panes of double- or triple-pane windows, that’s a red flag. It typically means the seal between the panes has failed, allowing moisture to seep in and get trapped. At that point, the insulating gas (usually argon or krypton) has likely escaped, which lowers the window’s energy efficiency.
If it’s on the interior side of the window, it’s often due to too much indoor humidity. In Spokane, where the weather can swing from damp and drizzly to frigid and dry, managing indoor air moisture is a balancing act.
What You Can Do About It
Ventilate your home - Use exhaust fans in bathrooms and kitchens. Crack a window when cooking or showering.
Use a dehumidifier - This is especially helpful during the wet season.
Check your windows - If seals are broken or the windows feel drafty, it might be time to replace or repair them.
Upgrade your windows - Modern energy-efficient windows with low-E coatings and better insulation can help prevent condensation from forming.
