Mold Moisture Problems and Ventilation

In the 1970s, many changes in building practices occurred when the Occupational Safety and Health Act was signed, creating the Occupational Safety and Health Administration (OSHA). OSHA would begin to regulate the construction industry on a federal level. In construction, OSHA's new regulations led to many buildings being constructed in a way that they were tightly sealed but did not always allow for adequate ventilation. These conditions can lead to moisture buildup, providing the perfect environment for mold growth. Not performing adequate or timely maintenance can also contribute to moisture control issues.

Not much moisture is necessary for mold growth. Condensation, as seen around a windowsill or in a bathroom, is plenty for growth. Places you will commonly find mold growing indoors include the following:

• Bathroom tile and grout
• Bathroom walls
• Basement walls
• In the vicinity of sinks
• In the vicinity of windows and doors

Some sources of moisture that put a structure at risk of mold growth are the following:

• Condensation from high levels of humidity
• Condensation from cold or hot spots in a building
• Roof leaks
• Plumbing leaks
• Flooding
• Sprinkler system leaks
• Humidification systems
