The windows of your home are a portal to the outdoors, a way to let light in as you take in the view of your garden, yard or scenery. The last thing you would want to see is a sweaty window plastered in a film of condensation.
Not only are windows covered in condensation unattractive, they also can be a sign of a more serious air-quality deficit inside your home. Fortunately, there’s numerous things you can try to address the problem.
What Causes Sweating along Windows
Condensation on the interior of windows is created by the humid warm air inside your home reaching the colder surface of your 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 crucial to recognize 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 on the inside of a window is produced from the warm humid air throughout your home collecting along the glass.
- The moisture you find between windowpanes is caused when the window seal stops working and moisture gets in 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 fixed by changing the humidity in your home. Numerous things produce humidity in a home, such as showers, cooking, taking a bath or even breathing.
Why Condensation on Windows Could Mean a Problem
Though you might consider condensation in your windows is a cosmetic problem, it could also be evidence your home has excess humidity. If that’s the case, water could also be collecting on window frames, cold walls or other surfaces. Even a thin film of water can help wood surfaces to mildew or rot over time, fostering the growth of mildew or mold.
How to Lower Humidity Inside Your Home
Thankfully there are several options for extracting moisture from the air throughout your home.
If you have a humidifier operating in your home – whether it be a smaller 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 excessive, think about installing a dehumidifier. While humidifiers adds moisture into your home so the air doesn’t become too dry, a dehumidifier extracts excess moisture out of the air.
Smaller, portable dehumidifiers can eliminate the water from a single room. However, portable units require emptying out water trays and generally service a somewhat limited area. A whole-house dehumidifier will extract moisture from your entire home.
Whole-house dehumidifier systems are managed by a humidistat, which permits you to set a humidity level just like you would select a temperature via your thermostat. The unit will begin running instantly when the humidity level overtakes the set level. These systems work with your home’s HVAC system, so you will want to contact qualified professionals for whole-house dehumidifier installation .
Alternative Ways to Lower Condensation on Windows
- Exhaust fans. Putting in exhaust fans in humidity hotspots like the bathroom, laundry room or above the stove can help by pulling the warm, moist air from these areas out of your home before it can raise the humidity level across your home.
- Ceiling fans. Spinning ceiling fans can also keep air flowing throughout the home so humid air doesn’t get trapped in one area.
- Open window treatments. Throwing open the blinds or drapes can lower condensation by preventing the warm air from being caught against the windowpane.
By lowering humidity in your home and dispersing air throughout your home, you can make the most of clear, moisture-free windows even during the winter.
