How Do You Prevent Mold Growth on Windowsills?

Mold isn’t only unsightly but can also be detrimental to the health of your family. It can grow on painted and stained windowsills due to condensation buildup or indoor airflow issues. Removing mold isn’t easy, so as much as possible, you want to prevent this problem even before it develops. 

Read on to learn how to prevent mold growth on windowsills from a double hung window repair expert.

What Causes this Problem?

Moisture accumulation around windows can cause mold to grow on the sills. Your daily activities, such as showering and cooking can increase moisture levels inside your home. Without proper airflow, moisture will get trapped indoors and cause mold growth. 

Moreover, condensation can occur during the colder months when heated air meets the cold window glass. Mold will start to grow when the condensation is left on the sill for a long time. Green mold is easier to remove than black mold, which isn’t as common but can be harmful to your health. These microorganisms can also grow on exterior window stools and outside sills. 

How to Prevent Mold Growth

Air and water can easily pass through windows that are not installed correctly. These windows are prone to water damage and mold. Make sure to hire a reputable contractor for your replacement window installation to avoid this problem. 

You can maintain good airflow in your home by setting your thermostat at 70 degrees with the fan on “auto” on warm days. Make sure to close your windows and doors when your air conditioner is on as the combination of warm and cool air can also cause moisture to accumulate on the sills. It will also help to install exhaust fans in your bathroom and kitchen to maintain healthy humidity levels. You can use a dehumidifier in rooms more likely to get damp like the basement.
