Conducive Conditions For Mold Growth

Airborne spores will eventually land and settle on a surface. Spores may or may not germinate immediately, but they are built for survival. The spores may lie dormant, waiting for the right condition for growth. The following conditions may be conducive for mold growth:

Moisture:  When looking for the source of a mold growth, look for moisture. Spores can survive in as little as 65% humidity.

Food Sources: Food sources for mold are the organic materials in a structure, such as wood, drywall, insulation, and natural fibers, which may have been exposed to moisture.

Raw Materials:  Even before a new home is built, it’s raw materials can collect moisture and mold, especially if it is exposed to the weather.

Minimal Air Circulation: An example of minimal air circulation is two pieces of wood coming together, such as where a floor joist meets a the band joist.

HVAC Systems: HVAC systems and ductwork often contains porous materials, moisture, and dirt.
