Mold growth may begin 48-72 hours after a surface has been exposed to high levels of moisture. The key to mold prevention is the removal of these scenarios that cause or lead to excess moisture. Water leaks, high humidity, and condensation all may lead to mold growth. Therefore, if you have a roof leak, fix it. If there are high humidity levels, invest in a dehumidifier to control the environment. If you experience a flood or leak, have it properly dried with the corresponding equipment to verify there is no humidity left behind. Also, make sure there is proper ventilation in areas such as bathrooms, laundry, and attics. Another key component in controlling the environment within your home or office is to maintain the AC at 78°, whether or not you are in town to prevent humidity levels from accumulating.
