The windows throughout your home are a portal to the outdoors, a way to let light in when you enjoy the view of your garden, yard or other surroundings. The last thing you would want to see is a sweaty window plastered in a coating of condensation.

Not only are windows plastered with condensation unappealing, they also can be evidence of a more serious air-quality issue inside your home. Fortunately, there’s multiple things you can do to address the problem.

What Produces Condensation in Windows

Condensation on the interior of windows is produced by the moist warm air inside your home hitting the cooler surface of the windows. It’s notably commonplace during the winter when it’s much chillier outside than it is in your home.

Inside Moisture vs. In Between Panes

When discussing condensation, it’s necessary to know the distinction 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 within a window is caused from the warm moist air in your home collecting against the glass.
  • The moisture you find between windowpanes is formed when the window seal fails and moisture seeps between the two panes of glass, in which case the window has to be repaired or replaced.
  • Condensation inside the windows isn’t a window situation and can instead be resolved by adjusting the humidity across your home. Numerous things generate humidity throughout a home, including showers, cooking, bathing or even breathing.

Why Condensation on Windows Can Be an Issue

Although you might presume condensation on the inside of your windows is a cosmetic problem, it may also be indicating your home has excess humidity. If this is in fact the case, water could also be collecting on window frames, cold walls or other surfaces. Even a small film of water can cause wood surfaces to mildew or rot over time, increasing the growth of mildew or mold.

How to Lower Humidity in Your Home

Thankfully there are several options for extracting moisture from the air inside your home.

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

If you don’t have a humidifier going and your home’s humidity level is higher than you prefer, think about getting a dehumidifier. While humidifiers adds moisture inside your home so the air doesn’t become too dry, a dehumidifier pulls excess moisture out of the air.

Small, portable dehumidifiers can absorb the water from one room. However, portable units require clearing water trays and usually service a somewhat limited area. A whole-house dehumidifier will remove moisture from your entire home.

Whole-house dehumidifier systems are controlled by a humidistat, which permits you to specify a humidity level just like you would pick a temperature via your thermostat. The unit will start immediately when the humidity level surpasses the set level. These systems coordinate with your home’s HVAC system, so you should contact skilled professionals for whole-house dehumidifier installation .

Other Ways to Reduce Condensation on Windows

  • Exhaust fans. Adding exhaust fans near humidity hotspots such as the bathroom, laundry room or above the stove can help by drawing the warm, moist air from these rooms out of your home before it can raise the humidity level throughout your home.
  • Ceiling fans. Running ceiling fans can also keep air circulating inside the home so humid air doesn’t get caught up in one spot.
  • Opening your window treatments. Throwing open the blinds or drapes can reduce condensation by stopping the humid air from being trapped against the windowpane.

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