The windows of your home open up to the outdoors, a way to let light in while you enjoy the view of your garden, yard or landscape. The last thing you need to see is a sweaty window plastered in a layer of condensation.

Not only are windows plastered with condensation unsightly, they also can be a sign of a larger air-quality deficit within your home. Luckily, there’s several things you can attempt to address the problem.

What Produces Sweating on Windows

Condensation on the inner layer of windows is formed by the damp warm air throughout your home mixing with the colder surface of the windows. It’s particularly common during the winter when it’s much colder outside than it is inside your home.

Inside Moisture vs. In Between Panes

When talking about condensation, it’s necessary to understand the contrast between moisture on the inside of your windows versus moisture in between the windowpanes. One is an air-quality issue and the other is a window issue.

  • Moisture inside a window is caused from the warm damp air in your home condensing on the glass.
  • The moisture you notice between windowpanes is caused when the window seal stops working and moisture seeps between the two panes of glass, and at that point the window needs to be repaired or replaced.
  • Condensation in the windows isn’t a window issue and can instead be solved by changing the humidity inside your home. Numerous things produce humidity throughout a home, including showers, cooking, bathing or even breathing.

Why Condensation on Windows Could Mean a Problem

Although you might think condensation on the inside of your windows is a cosmetic issue, it can be a sign your home has excess humidity. If that’s the case, water may also be condensing on window frames, cold walls or other surfaces. Even a small film of water can cause wood surfaces to mildew or rot over time, promoting the growth of mildew or mold.

How to Decrease Humidity in Your Home

The good news is there are various options for removing moisture from the air throughout your home.

If you have a humidifier running in your home – whether it be a small unit or a whole-house humidifier – lower it further so the humidity inside your home goes down.

If you don’t have a humidifier active and your home’s humidity level is excessive, think about installing a dehumidifier. While humidifiers put moisture in your home so the air doesn’t dry out, a dehumidifier pulls excess moisture out of the air.

Smaller, portable dehumidifiers can remove the water from an entire room. However, those units require clearing water trays and generally service a somewhat limited area. A whole-house dehumidifier will eliminate moisture across your entire home.

Whole-house dehumidifier systems are managed by a humidistat, which permits you to specify a humidity level just like you would select a temperature with your thermostat. The unit will start automatically when the humidity level exceeds the set level. These systems collaborate with your home’s HVAC system, so you will receive the best results if you contact skilled professionals for whole-house dehumidifier installation Streamwood.

Alternative Ways to Reduce Condensation on Windows

  • Exhaust fans. Installing exhaust fans near humidity hotspots like the bathroom, laundry room or above the kitchen range can help by drawing the warm, humid air from these rooms out of your home before it can elevate the humidity level throughout your home.
  • Ceiling fans. Turning on ceiling fans can also keep air circulating within the home so humid air doesn’t get trapped in one area.
  • Open window treatments. Throwing open the blinds or drapes can decrease condensation by preventing the damp air from being trapped against the windowpane.

By decreasing humidity inside your home and moving air throughout your home, you can take advantage of clear, moisture-free windows even in the winter.
