The windows in your home are a portal to the outdoors, a way to draw light in while you take in the view of your garden, yard or landscape. The last thing you want to see is a sweaty window coated in a coating of condensation.

Not only are windows covered in condensation unsightly, they also can be evidence of a larger air-quality deficit inside your home. Fortunately, there’s multiple things you can attempt to resolve the problem.

What Causes Condensation along Windows

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

Inside Moisture vs. In Between Panes

When talking about condensation, it’s crucial to understand 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 on the inside of a window is created from the warm damp air in your home forming along the glass.
  • The moisture you find between windowpanes is caused when the window seal fails and moisture slips 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 issue and can instead be resolved by fine-tuning the humidity in your home. Many things cause humidity throughout a home, like showers, cooking, bathing or even breathing.

Why Indoor Sweating on Windows Can Be a Problem

Though you might think condensation inside your windows is a cosmetic issue, it could also be evidence your home has high humidity. If this is in fact the case, water may also be condensing on window frames, cold walls or other surfaces. Even a thin 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

Not to worry, because there are several options for extracting moisture from the air inside your home.

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

If you don’t have a humidifier active and your home’s humidity level is high, look into getting 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.

Compact, portable dehumidifiers can absorb the water from one room. However, these units require clearing water trays and usually service a small area. A whole-house dehumidifier will extract moisture from your entire home.

Whole-house dehumidifier systems are regulated by a humidistat, which allows you to set a humidity level just like you would choose a temperature with your thermostat. The unit will begin running instantly when the humidity level exceeds the set level. These systems coordinate with your home’s HVAC system, so you should contact skilled professionals for whole-house dehumidifier installation Des Moines.

Other Ways to Lower 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, humid air from these spaces out of your home before it can raise the humidity level inside your home.
  • Ceiling fans. Spinning ceiling fans can also keep air flowing within the home so humid air doesn’t get trapped in one spot.
  • Opening your window treatments. Opening the blinds or drapes can reduce condensation by preventing the warm air from being stuck against the windowpane.

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