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

Not only are windows covered in condensation unsightly, they also can be evidence of a more substantial air-quality issue in your home. Luckily, there’s several things you can try to address the problem.

What Creates Sweating along Windows

Condensation on the interior of windows is created by the moist warm air inside your home reaching the colder surface of the windows. It’s notably commonplace during the winter when it’s much cooler outside than it is inside your home.

Inside Moisture vs. In Between Panes

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

  • Moisture inside a window is created from the warm humid air throughout your home collecting along the glass.
  • Any moisture you find between windowpanes is produced when the window seal stops working and moisture gets in between the two panes of glass, in which case the window needs to 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. Numerous things produce humidity throughout a home, such as showers, cooking, bathing or even breathing.

Why Indoor Sweating on Windows Could Mean a Problem

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

How to Reduce Humidity in Your Home

Fortunately there are numerous options for eliminating moisture from the air throughout your home.

If you have a humidifier operating in 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 higher than you prefer, consider installing a dehumidifier. While humidifiers introduces moisture in your home so the air doesn’t become too dry, a dehumidifier pulls excess moisture out of the air.

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

Whole-house dehumidifier systems are regulated by a humidistat, which allows you to set a humidity level just like you would choose a temperature on your thermostat. The unit will start automatically when the humidity level surpasses the set level. These systems work with your home’s HVAC system, so you should contact experienced professionals for whole-house dehumidifier installation Reinholds.

Other Ways to Lower Condensation on Windows

  • Exhaust fans. Installing exhaust fans in humidity hotspots like 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 increase the humidity level across your home.
  • Ceiling fans. Running ceiling fans can also keep air moving throughout the home so humid air doesn’t get trapped in one place.
  • Open window treatments. Throwing open the blinds or drapes can decrease condensation by stopping the damp air from being trapped against the windowpane.

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