Molds

Frequently Asked Questions

 

What Are Molds?
Molds are a leading cause of poor indoor air quality in the homes of most residents in the U.S. Molds are small, microscopic organisms found both indoors and outdoors. They have tiny, light spores that travel through the air throughout buildings. In order for molds to grow, the spores need moisture, warmth, still air and food source. They land on moist surfaces of food, plants, dry leaves, etc. and multiply. Molds can be white, orange, green, brown or black and they have an earthy or musty odor.

Where Do Molds Grow in the Home?
Mold is most likely to grow in poorly ventilated and damp places indoors such as:

  • showers / bathrooms
  • damp basements
  • backed-up sewers
  • leaky roofs
  • humidifiers
  • constant plumbing leaks
  • wet wood
  • ceiling tiles
  • wallpaper
