The winter is hard on the replacement windows on your Tacoma, WA home, and an icy build up is a tell-tale sign that something is wrong. Luckily, replacement window experts know the truth about ice buildup and are ready and waiting to offer information and solutions.

Keep reading for more information on the causes of ice buildup on the inside of windows, the potential impacts and concerns if not addressed, and how to fix the problem.

There is always water in the air in the form of vapor. In the summertime when the temperatures are high, this vapor shows up in the form of humidity. In the winter, however, this vapor condenses in the cold and sticks to surfaces. Outside, this condensation and freezing leads to frost. Inside, it can cause icy windows. When the temperature outside goes below what temperature causes water to freeze, the vapor changes from a gas to liquid - condensation. As the outside temperature of a window’s glass gets colder and is then exposed to the warm moist air inside, the vapor condenses on the windowpane and then freezes into ice crystals.

While this ice seems harmless, it can actually lead to structural and aesthetic issues with the window frame and window finish. For example, when the ice melts into liquid it can sit on the window frame and warp the material, ruin the topcoat, rot the wood, and even cause mildew and mold to grow. Single-pane windows are especially at risk for the damage that can come with ice buildup. The extra pane in double-pane windows can trap any excess moisture, so without that trap, single-pane windows can even leak water into the surrounding wall and cause mold to grow.

Try these helpful tips and tricks if you want to stop ice buildup from hurting your windows:

  • Get Replacement Windows – New replacement windows, especially double and triple pane, are less likely to have ice buildup and ice buildup damage.
  • Don’t Over-Water – Over-watering your house plants can also lead to excess moisture.
  • Increase Room Temperature – Increase a room’s temperature at nighttime to stop the ice from forming.
  • Check Gas Appliances – Gas appliances can malfunction and cause extra water vapor and even toxic chemicals to leak out.
  • Repair Leaks – Leaky faucets and pipes can easily contribute to the amount of water in the air inside your home. Check for and repair any plumbing leaks.
  • Dry Clothes Outside – If you line-dry your clothing, be sure to dry it outside so the water doesn’t stick around as vapor inside your home.
  • Absorb Condensation – Try putting rolled up towels on your windowsills overnight. The towels can help catch and trap extra condensation before it can seep into the windowsill and cause damage.
