Why do many homes need a foundation vent well?

Foundation vents are necessary to prevent mold, mildew, and bacteria from invading your home. Wood rot, metal rust, and pests will no doubt follow. To avoid all of them, you need to make sure your basement and foundation area has proper ventilation.
One of the most common ways to ensure fresh air circulation is with basement windows and foundation vents. Both methods require secure access to the ground-level area on the outer side of the building. Foundation vent window wells are used to provide adequate clear space for the ventilation installation.
