Moisture and Suspect Growth

Mold is present everywhere in indoor and outdoor environments, so it is not possible to eliminate all mold spores. The best method of mitigating mold growth in buildings is to address water and moisture issues quickly and perform repairs necessary to control moisture. Hawthorne identifies any potential mold complaints as Suspect Growth.

Suspect Growth typically grows where there is moisture, high humidity, and/or water intrusion, and may go undiscovered until it becomes visible (i.e., surface discoloration and/or odor.) The conditions necessary for suspect growth to occur on surfaces are moisture and a food source. Contributing factors may include:

• Excess thermostat temperature settings (too hot/cold) or fan set to “on” position • High humidity • Broken bathroom exhaust fan • Exhaust fan covers blocked with lint • Leaking hot water heaters • Water leaks from sinks, dishwashers, clothes washers, toilets, or hidden pipes • Condensation around windows • Roof or window leaks • Water intrusion around balconies, patios, windows, or doors

To control moisture inside:

• Inspect occupied apartment homes on a quarterly basis.

• Maintain ideal parameters of the following items: - Humidity below 60% Ideally 30% 50% - Temperature Between 65° and 75° - Moisture Content of materials below 10%

• Inspect vacant apartments regularly. Set thermostats at levels appropriate for the time of year and your climate to control humidity. Team members unsure of the appropriate settings should contact the Regional Service Director for guidance.
