Why Your Windows Are Sweating Indoors and How to Fix It

September 27, 2022

The windows throughout your home are a portal to the outdoors, a way to let 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 coated in a layer of condensation.

Not only are windows plastered with condensation unappealing, they also can be a symptom of a larger air-quality problem in your home. Luckily, there’s numerous things you can do to resolve the problem.

What Causes Condensation along Windows

Condensation on the interior of windows is formed by the damp warm air throughout your home hitting the colder surface of the windows. It’s notably prevalent in the winter when it’s much cooler outside than it is in your home.

Inside Moisture vs. In Between Panes

When dealing with condensation, it’s important to recognize the contrast 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 inside a window is produced from the warm moist air inside your home condensing along the glass.
  • Existing moisture you notice between windowpanes is caused when the window seal breaks down and moisture gets in between the two panes of glass, and at that point the window has to be repaired or replaced.
  • Condensation inside the windows isn’t a window problem and can instead be fixed by changing the humidity inside your home. Different things produce humidity throughout a home, such as showers, cooking, taking a bath or even breathing.

Why Condensation on Windows Can Be a Problem

Even though you might consider condensation inside your windows is a cosmetic concern, it may also be a sign your home has excess humidity. If that’s the case, water may also be accumulating on window frames, cold walls or other surfaces. Even a slim film of water can help wood surfaces to mildew or rot over time, increasing the growth of mildew or mold.

How to Decrease Humidity in Your Home

The good news is there are numerous options for removing moisture from the air throughout 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 comes down.

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

Small, portable dehumidifiers can absorb the water from an entire room. However, portable units require emptying water trays and usually service a somewhat limited area. A whole-house dehumidifier will eliminate moisture from your entire home.

Whole-house dehumidifier systems are controlled by a humidistat, which enables you to establish a humidity level just as you would pick a temperature via your thermostat. The unit will run immediately when the humidity level overtakes the set level. These systems work with your home’s HVAC system, so you will receive the best results if you contact qualified professionals for whole-house dehumidifier installation Neptune City.

Additional Ways to Eliminate Condensation on Windows

  • Exhaust fans. Putting in exhaust fans around humidity hotspots including the bathroom, laundry room or above the oven can help by extracting the warm, moist air from these areas out of your home before it can elevate the humidity level in your home.
  • Ceiling fans. Spinning ceiling fans can also keep air moving throughout the home so humid air doesn’t get trapped in one place.
  • Opening your window treatments. Opening the blinds or drapes can lower condensation by stopping the damp air from being stuck against the windowpane.

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