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

Not only are windows covered in condensation unattractive, they also can be a sign of a more substantial air-quality problem within your home. Fortunately, there’s several things you can do to address the problem.

What Creates Sweating on Windows

Condensation on the inside of windows is produced by the moist warm air inside your home reaching the cold surface of your windows. It’s especially common in the winter when it’s much cooler outside than it is in your home.

Inside Moisture vs. In Between Panes

When discussing condensation, it’s necessary to understand 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 created from the warm moist air throughout your home forming against the glass.
  • Any moisture you find between windowpanes is produced 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 solved by fine-tuning the humidity inside your home. Different things generate humidity inside a home, such as showers, cooking, laundry or even breathing.

Why Sweating Windows Can Be an Issue

Even though you might consider condensation in your windows is a cosmetic issue, it could also be indicating your home has excess humidity. If this is in fact the case, water may also be accumulating on window frames, cold walls or other surfaces. Even a thin film of water can encourage wood surfaces to mildew or rot over time, promoting the growth of mildew or mold.

How to Lower Humidity Throughout Your Home

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

If you have a humidifier operating 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 excessive, consider installing a dehumidifier. While humidifiers adds moisture inside your home so the air doesn’t get too dry, a dehumidifier draws excess moisture out of the air.

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

Whole-house dehumidifier systems are controlled by a humidistat, which allows you to establish a humidity level the same like you would pick a temperature via your thermostat. The unit will start automatically when the humidity level exceeds the set level. These systems coordinate with your home’s HVAC system, so you will want to contact qualified professionals for whole-house dehumidifier installation Manassas.

Other Ways to Decrease Condensation on Windows

  • Exhaust fans. Installing exhaust fans in humidity hotspots including the bathroom, laundry room or above the stove can help by extracting the warm, moist air from these spaces out of your home before it can increase the humidity level in 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 place.
  • Opening your window treatments. Throwing open the blinds or drapes can lower condensation by preventing the humid air from being caught against the windowpane.

By decreasing humidity across your home and moving air throughout your home, you can enjoy clear, moisture-free windows even during the winter.
