How do Molds affect people? - By Harry Cannon

Molds are usually not a problem indoors, unless mold spores land on a wet or damp spot and begin growing.  Molds have the potential to cause health problems.  Molds produce allergens (substances that can cause allergic reactions), irritants, and in some cases, potentially toxic substances (mycotoxins).  Inhaling or touching mold or mold spores may cause allergic reactions in sensitive individuals.

Allergic responses include hay fever-type symptoms, such as sneezing, runny nose, red eyes, and skin rash (dermatitis).  Allergic reactions to mold are common.  They can be immediate or delayed.  Molds can also cause asthma attacks in people with asthma who are allergic to mold.  In addition, mold exposure can irritate the eyes, skin, nose, throat, and lungs of both mold-allergic and non-allergic people.  Symptoms other than the allergic and irritant types are not commonly reported as a result of inhaling mold.

80% of most indoor mold issues begin in the crawl space. A damp crawl space (19% moisture content and above) will provide an environment conducive for mold growth. High moisture can come from lack of a vapor barrier (plastic), HVAC condensation, lack of air flow, poor drainage, or many other factors. Visible growth, standing water, musty odors and hanging insulation are indications that there is a problem.

Once mold begins to grow in these conditions it can spread throughout a building interior. The initial growth can be spread more quickly once it gets into the HVAC system and ductwork. If you are experiencing any of these indicators it is best to call a mold professional to perform an assessment. Here in NENC you can call Dwelling Management Solutions at 252.339.2489.
