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

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

What Creates Sweating along Windows

Condensation on the inner layer of windows is produced by the humid warm air in your home reaching the cooler surface of your windows. It’s particularly prevalent during the winter when it’s much chillier outside than it is inside your home.

Inside Moisture vs. In Between Panes

When discussing condensation, it’s necessary to understand the difference between moisture on the inside of your windows versus moisture in between the windowpanes. One is an indoor air quality issue and the other is a window issue.

  • Moisture inside a window is created from the warm damp air inside your home forming against the glass.
  • Existing moisture you notice between windowpanes is caused when the window seal fails and moisture slips between the two panes of glass, and by then the window should be repaired or replaced.
  • Condensation on the inside of the windows isn’t a window situation and can instead be resolved by changing the humidity inside your home. Many things generate humidity in a home, like showers, cooking, laundry or even breathing.

Why Sweating Windows Could Mean a Problem

Although you might presume condensation on the inside of your windows is a cosmetic concern, it may also be evidence your home has high humidity. If that’s the case, water might also be accumulating on window frames, cold walls or other surfaces. Even a small film of water can encourage wood surfaces to mildew or rot over time, promoting the growth of mildew or mold.

How to Reduce Humidity Throughout Your Home

The good news is there are numerous options for extracting moisture from the air in your home.

If you have a humidifier operating inside 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 running and your home’s humidity level is high, think about purchasing a dehumidifier. While humidifiers introduces moisture inside your home so the air doesn’t dry out, a dehumidifier draws excess moisture out of the air.

Smaller, portable dehumidifiers can remove the water from a single room. However, portable units require emptying water trays and usually service a fairly small area. A whole-house dehumidifier will eliminate moisture from your entire home.

Whole-house dehumidifier systems are managed by a humidistat, which enables you to establish a humidity level just like you would select a temperature with your thermostat. The unit will start immediately when the humidity level overtakes the set level. These systems collaborate with your home’s HVAC system, so you should contact experienced professionals for whole-house dehumidifier installation Wilmington.

Other Ways to Lower Condensation on Windows

  • Exhaust fans. Adding exhaust fans in humidity hotspots like the bathroom, laundry room or above the kitchen range can help by extracting the warm, moist air from these spaces out of your home before it can increase the humidity level inside your home.
  • Ceiling fans. Spinning ceiling fans can also keep air flowing inside the home so humid air doesn’t get caught up in one spot.
  • Opening up window treatments. Pulling open the blinds or drapes can decrease condensation by preventing the warm air from being trapped 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 middle of the winter.
