The windows in your home open up to the outdoors, a way to allow light in when you appreciate the view of your garden, yard or scenery. The last thing you need to see is a sweaty window covered in a layer of condensation.

Not only are windows coated in condensation unappealing, they also can be a symptom of a more serious air-quality deficit inside your home. Thankfully, there’s several things you can try to resolve the problem.

What Causes Condensation on Windows

Condensation on the interior of windows is produced by the humid warm air inside your home mixing with the colder surface of your windows. It’s particularly commonplace in the winter when it’s much cooler outside than it is in your home.

Inside Moisture vs. In Between Panes

When talking about condensation, it’s necessary to know the contrast 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 produced from the warm damp air inside your home forming on the glass.
  • The moisture you see between windowpanes is formed when the window seal breaks down and moisture slips between the two panes of glass, and by then the window has to be repaired or replaced.
  • Condensation inside the windows isn’t a window issue and can instead be resolved by fine-tuning the humidity across your home. Many things cause humidity throughout a home, including showers, cooking, bathing or even breathing.

Why Condensation on Windows Could Mean Trouble

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

How to Lower Humidity Inside Your Home

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

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

If you don’t have a humidifier going and your home’s humidity level is excessive, consider getting a dehumidifier. While humidifiers put moisture into your home so the air doesn’t become too dry, a dehumidifier draws excess moisture out of the air.

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

Whole-house dehumidifier systems are managed by a humidistat, which allows you to establish a humidity level just like you would pick a temperature on your thermostat. The unit will begin running automatically when the humidity level overtakes the set level. These systems coordinate with your home’s HVAC system, so you should contact experienced professionals for whole-house dehumidifier installation Justin.

Other Ways to Decrease Condensation on Windows

  • Exhaust fans. Putting in exhaust fans around humidity hotspots like the bathroom, laundry room or above the oven can help by drawing the warm, humid air from these areas out of your home before it can raise the humidity level across your home.
  • Ceiling fans. Turning on ceiling fans can also keep air flowing within the home so humid air doesn’t get trapped in one area.
  • Opening your window treatments. Opening the blinds or drapes can lower condensation by stopping the humid air from being trapped against the windowpane.

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