The windows of your home are a gateway to the outdoors, a way to let light in while you enjoy the view of your garden, yard or scenery. The last thing you want to see is a sweaty window covered in a layer of condensation.

Not only are windows coated in condensation unattractive, they also can be a sign of a more serious air-quality issue in your home. Luckily, there’s several things you can try to correct the problem.

What Causes Condensation on Windows

Condensation on the inner layer of windows is created by the humid warm air throughout your home mixing with the colder surface of your windows. It’s particularly prevalent in the winter when it’s much colder outside than it is within your home.

Inside Moisture vs. In Between Panes

When discussing condensation, it’s crucial to know 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 created from the warm damp air throughout your home collecting on the glass.
  • The moisture you see between windowpanes is produced when the window seal breaks down and moisture slips between the two panes of glass, and by then the window needs to be repaired or replaced.
  • Condensation on the inside of the windows isn’t a window problem and can instead be solved by adjusting the humidity in your home. Many things produce humidity in a home, such as showers, cooking, laundry or even breathing.

Why Indoor Sweating on Windows Can Be an Issue

Though you might consider condensation inside your windows is a cosmetic problem, it could also be a sign your home has higher humidity. If that’s the case, water might also be collecting on window frames, cold walls or other surfaces. Even a slim film of water can help wood surfaces to mildew or rot over time, increasing the growth of mildew or mold.

How to Decrease Humidity Throughout Your Home

Thankfully there are numerous options for removing moisture from the air in your home.

If you have a humidifier running 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 active and your home’s humidity level is excessive, consider getting a dehumidifier. While humidifiers introduces moisture inside your home so the air doesn’t get too dry, a dehumidifier draws excess moisture out of the air.

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

Whole-house dehumidifier systems are controlled by a humidistat, which permits you to establish a humidity level just like you would pick a temperature via your thermostat. The unit will begin running instantly when the humidity level surpasses the set level. These systems work with your home’s HVAC system, so you should contact qualified professionals for whole-house dehumidifier installation Mason City.

Alternative Ways to Decrease Condensation on Windows

  • Exhaust fans. Adding exhaust fans in humidity hotspots such as the bathroom, laundry room or above the kitchen range can help by drawing the warm, moist air from these areas out of your home before it can elevate the humidity level across your home.
  • Ceiling fans. Running ceiling fans can also keep air swirling within the home so humid air doesn’t get caught up in one place.
  • Opening up window treatments. Pulling open the blinds or drapes can decrease condensation by stopping the damp air from being stuck against the windowpane.

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