Most homeowners think of mold as a problem in basements, laundry rooms, or crawl spaces only. But knowing what really causes mold on windows doesn’t limit its growth to these areas of your home. Actually, mold can grow anywhere there is an accumulation of excess moisture and the proper temperature.

Sometimes mold can be invisible on the glass, matching the color of the window itself. Other times, mold can be identified as a green, white, yellow, pink, or black – depending on the specific mold spores.

The CDC cites the mold around window sill as an increasing concern, with serious possible side effects such as memory loss and lack of energy. Follow these general guidelines to remove mold from windows:
- Dampen the mold by spraying with water from a spray bottle to prevent mold spores from circulating in the air.
- It is recommended to wear gloves, an air mask, and safety goggles for personal protection.
- With a non-abrasive brush, scrub the mold around windows with a solution of 1/4 to 1/2 cup bleach added to a gallon of water.

Replacing your windows is always an option for ensuring the complete removal of mold on windows.
