Ten Things You Should Know About Mold

  • Potential health effects and symptoms associated with mold exposures include allergic reactions, asthma, and other respiratory complaints.
  • There is no practical way to eliminate all mold and mold spores in the indoor environment; the way to control indoor mold growth is to control moisture.
  • If mold is a problem in your home or school, you must clean up the mold and eliminate sources of moisture.
  • Fix the source of the water problem or leak to prevent mold growth.
  • Reduce indoor humidity (to 30-60%) to decrease mold growth by:

a. venting bathrooms, dryers, and other moisture-generating sources to the outside;
b. using air conditioners and de-humidifiers;
c. increasing ventilation;
d. and using exhaust fans whenever cooking, dishwashing, and cleaning.

  • Clean and dry any damp or wet building materials and furnishings within 24-48 hours to prevent mold growth.
  • Clean mold off hard surfaces with water and detergent, and dry completely. Absorbent materials such as ceiling tiles, that are moldy, may need to be replaced.
  • Prevent condensation: Reduce the potential for condensation on cold surfaces (i.e., windows, piping, exterior walls, roof, or floors) by adding insulation.
  • In areas where there is a perpetual moisture problem, do not install carpeting (i.e., by drinking fountains, by classroom sinks, or on concrete floors with leaks or frequent condensation).
  • Molds can be found almost anywhere; they can grow on virtually any substance, providing moisture is present. There are molds that can grow on wood, paper, carpet, and foods.
