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

Not only are windows coated in condensation unappealing, they also can be evidence of a more substantial air-quality deficit within your home. Fortunately, there’s multiple things you can do to correct the problem.

What Causes Sweating along Windows

Condensation on the inside of windows is formed by the damp warm air inside your home mixing with the colder surface of your windows. It’s particularly commonplace around 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 recognize the distinction 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 produced from the warm moist air inside your home forming against the glass.
  • The moisture you find between windowpanes is produced when the window seal breaks down and moisture seeps between the two panes of glass, and at that point the window needs to be repaired or replaced.
  • Condensation inside the windows isn’t a window problem 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 Sweating Windows Could Mean Trouble

Though you might presume condensation inside your windows is a cosmetic problem, it could also be indicating your home has high humidity. If this is in fact the case, water could also be collecting on window frames, cold walls or other surfaces. Even a slim film of water can cause wood surfaces to mildew or rot over time, increasing the growth of mildew or mold.

How to Lower Humidity Inside Your Home

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

If you have a humidifier operating in your home – whether it be a small 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 high, consider installing a dehumidifier. While humidifiers put moisture in your home so the air doesn’t get too dry, a dehumidifier extracts excess moisture out of the air.

Compact, portable dehumidifiers can eliminate the water from an entire room. However, these units require clearing water trays and generally service a small area. A whole-house dehumidifier will eliminate moisture throughout your entire home.

Whole-house dehumidifier systems are managed by a humidistat, which enables you to establish a humidity level the same like you would choose a temperature with your thermostat. The unit will begin running automatically when the humidity level overtakes the set level. These systems work with your home’s HVAC system, so you will want to contact experienced professionals for whole-house dehumidifier installation Wilmington.

Additional Ways to Reduce Condensation on Windows

  • Exhaust fans. Installing exhaust fans in humidity hotspots including 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 elevate the humidity level in your home.
  • Ceiling fans. Turning on ceiling fans can also keep air circulating throughout 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 preventing the warm air from being trapped against the windowpane.

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