Can Mold in Basement Insulation Cause Heath Problems?

Mold can develop in moist and damp areas as well as in areas with little air flow, such as the basement and the insulation in your home. Not everyone is susceptible to health complications caused by mold in the home, but there are a few facts about mold and its effects everyone should know.

  1. Identification

    • Mold is a microscopic organism that feeds on organic matter and thrives in moist areas. Mold reproduces by releasing spores. These spores enter into the air and can be inhaled by occupants of the building. Mold produces a must smell and can be identified by patches of black, green or gray slime or fuzz. However, mold does not have to be visible to affect the air quality of a building.

    Significance

    • Most healthy individuals with normal immune systems will not be affected by mold. However, those with asthma or allergies can be affected by the presence of mold spores in the air. Symptoms include, sneezing, runny nose, coughing and difficulty breathing.

    Warning

    • Some molds, though not all, produce a substance called mycotoxins. These mycotoxins can cause fatigue, nausea, burning eyes and lungs and headaches if someone is exposed to high levels. Seek medical health immediately if you suspect mold contamination.

    Considerations

    • Mold in the insulation in your basement might not affect your overall air quality. Spores typically are released only when the mold is disturbed. Most homes have a small amount of mold but not enough to cause health issues. However, if you are experiencing health problems, can smell mold or see mold, you might well have a problem.

    Prevention/Solution

    • The best method for controlling mold is to dry the area. Fix any leaks in the roof or plumbing. Encourage air flow by ventilating and insulating attics and crawlspace. Install plastic sheeting over mold to prevent it from becoming moist. Vacuum regularly to remove spores. Install exhaust fans in the bathroom and other areas that have a lot of moisture.

      If you suspect a mold infestation, send a physical sample of the mold to a lab for testing (see Resources). Air samples are largely considered unreliable.
