The windows in your home open up to the outdoors, a way to allow light in while you take in the view of your garden, yard or scenery. The last thing you want to see is a sweaty window plastered in a film of condensation.

Not only are windows plastered with condensation unattractive, they also can be evidence of a larger air-quality deficit within your home. Luckily, there’s numerous things you can attempt to correct the problem.

What Produces Condensation on Windows

Condensation on the inside of windows is created by the damp warm air throughout your home mixing with the colder surface of your windows. It’s notably commonplace around the winter when it’s much chillier outside than it is in your home.

Inside Moisture vs. In Between Panes

When talking about condensation, it’s necessary to recognize the difference 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 on the inside of a window is produced from the warm humid air in your home condensing along the glass.
  • Any moisture you see between windowpanes is formed when the window seal breaks down and moisture slips between the two panes of glass, in which case the window should be repaired or replaced.
  • Condensation inside the windows isn’t a window issue and can instead be fixed by changing the humidity inside your home. Numerous things cause humidity in a home, such as showers, cooking, laundry or even breathing.

Why Condensation on Windows Could Mean a Problem

Though you might consider condensation inside your windows is a cosmetic issue, it can be evidence your home has excess humidity. If this is the case, water may also be accumulating on window frames, cold walls or other surfaces. Even a thin film of water can help 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 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 unit or a whole-house humidifier – lower it further so the humidity inside your home goes down.

If you don’t have a humidifier going and your home’s humidity level is excessive, consider getting a dehumidifier. While humidifiers adds moisture in your home so the air doesn’t become too dry, a dehumidifier draws excess moisture out of the air.

Small, portable dehumidifiers can eliminate the water from one room. However, portable units require emptying water trays and most often service a small area. A whole-house dehumidifier will eliminate moisture from your entire home.

Whole-house dehumidifier systems are controlled by a humidistat, which permits you to set a humidity level precisely like you would select a temperature via your thermostat. The unit will start immediately when the humidity level surpasses 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 .

Additional Ways to Reduce Condensation on Windows

  • Exhaust fans. Putting in exhaust fans near humidity hotspots including the bathroom, laundry room or above the oven can help by drawing the warm, moist air from these rooms out of your home before it can increase the humidity level in your home.
  • Ceiling fans. Turning on ceiling fans can also keep air swirling throughout the home so humid air doesn’t get caught up in one area.
  • Open window treatments. Pulling open the blinds or drapes can reduce condensation by preventing the humid air from being caught against the windowpane.

By decreasing humidity inside your home and dispersing air throughout your home, you can make the most of clear, moisture-free windows even in the middle of the winter.
