The windows of your home are a gateway to the outdoors, a way to allow light in while you appreciate the view of your garden, yard or landscape. The last thing you want to see is a sweaty window plastered in a layer of condensation.

Not only are windows covered in condensation unsightly, they also can be a sign of a larger air-quality problem throughout your home. Thankfully, there’s numerous things you can try to resolve the problem.

What Causes Sweating along Windows

Condensation on the inner layer of windows is produced by the damp warm air inside your home reaching the colder surface of your windows. It’s notably prevalent over the winter when it’s much chillier outside than it is inside your home.

Inside Moisture vs. In Between Panes

When talking about condensation, it’s important to know the difference between moisture on the inside of your windows in comparison 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 caused from the warm damp air in your home condensing on the glass.
  • Existing moisture you see between windowpanes is formed when the window seal fails and moisture slips between the two panes of glass, and at that point the window has to be repaired or replaced.
  • Condensation in the windows isn’t a window problem and can instead be resolved by adjusting the humidity in your home. Different things cause humidity throughout a home, like showers, cooking, taking a bath or even breathing.

Why Sweating Windows Could Mean a Problem

Although you might think condensation on the inside of your windows is a cosmetic concern, it could also be indicating your home has excess humidity. If this is in fact the case, water could also be condensing on window frames, cold walls or other surfaces. Even a small film of water can cause wood surfaces to mildew or rot over time, fostering the growth of mildew or mold.

How to Decrease Humidity Throughout Your Home

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

If you have a humidifier active in your home – whether it be a small-scale unit or a whole-house humidifier – lower it further so the humidity inside your home comes down.

If you don’t have a humidifier going and your home’s humidity level is higher than you prefer, look into installing a dehumidifier. While humidifiers introduces moisture inside your home so the air doesn’t dry out, a dehumidifier extracts excess moisture out of the air.

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

Whole-house dehumidifier systems are regulated by a humidistat, which permits you to set a humidity level just like you would select a temperature on your thermostat. The unit will run automatically when the humidity level exceeds the set level. These systems coordinate with your home’s HVAC system, so you should contact qualified professionals for whole-house dehumidifier installation Norco and St. Charles Parish.

Alternative Ways to Reduce Condensation on Windows

  • Exhaust fans. Installing exhaust fans around humidity hotspots such as the bathroom, laundry room or above the stove can help by pulling the warm, humid air from these spaces out of your home before it can elevate the humidity level throughout your home.
  • Ceiling fans. Turning on ceiling fans can also keep air swirling inside the home so humid air doesn’t get stuck in one area.
  • Open window treatments. Throwing open the blinds or drapes can lower condensation by stopping the warm air from being stuck against the windowpane.

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