What causes mold to grow in homes?

Thumbtack Editors

Mold can grow in your home in a lot of different ways: through open doors or windows, your ventilation, and heating or air conditioning system. 

Once inside, mold can grow if there’s enough moisture, which can collect in a home after a flood or around leaky faucets, roofing, windows or pipes. It can also grow in dust, fabric, insulation, wallpaper, wood, floors and ceilings.
