Do My New Replacement Windows or Doors in Hanover, MA Cause Condensation?

Published on

Normally during colder months you may start seeing condensation on your windows and doors. While it’s easy to think it’s time to find the cause, it actually tells you that your windows and doors are doing what they’re intended to do.

The good part is that there are a couple ways you can take this problem head-on to minimize it from happening in the future. To fully realize what is happening with your replacement windows and doors, take a few moments to read through the FAQs below.

Do my new replacement windows or doors cause condensation?

The simple way to answer this question is to say no. When you first catch a glimpse of condensation you may think there’s an issue with the window since that is where the water is forming. In reality, that’s not what’s happening. The fact that condensation is appearing proves that your windows and doors are doing what they’re supposed to do. Buying replacement windows and doors for those old drafty windows and doors decreases airflow in your home, making an even tighter seal. Homes with tighter seals actually hold more humidity. Prior to replacing your windows or doors, the dryer, colder air was able to leak in to your home, mixing with the warmer, more humid air inside. When mixed, the air’s humidity was lower, reducing the opportunity for condensation to form. So those new replacement windows and doors may have actually resulted in a higher humidity level in your home to rise.

How does condensation form?

Condensation happens when colder surfaces like windows and doors cool the nearby humid air. The water vapor in the air then goes back to water in its liquid form. In really cold climates, the interior surface can get so cold that the condensation can become frost or ice. Experiencing condensation on the interior or exterior paint is normal as well, especially when the indoor and outdoor temperatures and humidity are far apart. For example, in the summer when you pull something cold out of the refrigerator, the air is humid and warm. That is why the cold item you just took out suddenly becomes wet as it is exposed to the warmer air. What happened is that the temperature of the item from the refrigerator is below the dew point temperature of the air, which is caused by condensation on the outside of that container.

What steps can I take to reduce the condensation and humidity in my home?

In order to decrease condensation, humidity levels in the home have to be controlled and you must create air movement. Using exhaust fans in the kitchen, laundry room and your bathrooms can help keep the air moving. You can also vent any gas burners, clothes dryers or other appliances to the outdoors to help as well. Also, be sure to turn off any furnace humidifiers or other humidifying devices in your home. To help lower the humidity in your home, you can use a dehumidifier or air out your house for a few minutes each day.

Understanding condensation is just the beginning to keeping your home at ideal comfort. If you have any questions about condensation and whether your replacement windows and doors are doing their jobs properly, give Pella Windows and Doors in Hanover a call or stop by the showroom.
