The windows in your home are a gateway to the outdoors, a way to allow light in when you appreciate the view of your garden, yard or other surroundings. The last thing you want to see is a sweaty window covered in a layer of condensation.

Not only are windows covered in condensation unattractive, they also can be a symptom of a more substantial air-quality problem inside your home. Luckily, there’s numerous things you can try to correct the problem.

What Causes Sweating in Windows

Condensation on the interior of windows is formed by the moist warm air throughout your home hitting the colder surface of your windows. It’s notably prevalent over the winter when it’s much colder outside than it is inside your home.

Inside Moisture vs. In Between Panes

When dealing with condensation, it’s important to recognize the difference between moisture on the inside of your windows compared to moisture in between the windowpanes. One is an indoor air quality issue and the other is a window issue.

  • Moisture within a window is caused from the warm damp air in your home forming against the glass.
  • Existing moisture you notice between windowpanes is produced when the window seal fails and moisture seeps between the two panes of glass, and at that point the window needs to be repaired or replaced.
  • Condensation inside the windows isn’t a window problem and can instead be solved by changing the humidity across your home. Different things generate humidity throughout a home, such as showers, cooking, laundry or even breathing.

Why Sweating Windows Could Mean Trouble

Although you might presume condensation inside your windows is a cosmetic concern, it can be evidence your home has excess humidity. If that’s the case, water might also be collecting on window frames, cold walls or other surfaces. Even a thin film of water can cause wood surfaces to mildew or rot over time, fostering the growth of mildew or mold.

How to Decrease Humidity in Your Home

Not to worry, because there are various options for eliminating moisture from the air in your home.

If you have a humidifier operating inside your home – whether it be a smaller unit or a whole-house humidifier – lower it further so the humidity inside your home comes down.

If you don’t have a humidifier going and your home’s humidity level is high, look into purchasing a dehumidifier. While humidifiers put moisture in your home so the air doesn’t get too dry, a dehumidifier pulls excess moisture out of the air.

Small, portable dehumidifiers can eliminate the water from an entire room. However, portable units require emptying water trays and most often service a small area. A whole-house dehumidifier will extract moisture across your entire home.

Whole-house dehumidifier systems are regulated by a humidistat, which allows you to specify a humidity level just like you would pick a temperature with your thermostat. The unit will start automatically when the humidity level surpasses the set level. These systems collaborate with your home’s HVAC system, so you will want to contact qualified professionals for whole-house dehumidifier installation Frederick.

Alternative Ways to Decrease Condensation on Windows

  • Exhaust fans. Putting in exhaust fans in humidity hotspots including the bathroom, laundry room or above the oven can help by drawing the warm, moist air from these spaces out of your home before it can increase the humidity level across your home.
  • Ceiling fans. Turning on ceiling fans can also keep air circulating within the home so humid air doesn’t get stuck in one place.
  • Opening up window treatments. Pulling open the blinds or drapes can decrease condensation by preventing the humid air from being stuck against the windowpane.

By lowering humidity in your home and dispersing air throughout your home, you can make the most of clear, moisture-free windows even in the middle of the winter.
