- 1). Ventilate your basement as often as you can. Open all windows and doors from time to time to allow fresh air to penetrate all corners of the basement. Poor air quality is the main cause for black mold growth so make sure that fresh air always circulates in your basement. Run a ventilator or an air conditioner in your basement to provide good, healthy air circulation.
- 2). Place a dehumidifier in your basement to pull excess moisture from the air. Note that moisture is the feeding ground for all kinds of mold spores, so eliminate the humidity factor to prevent black mold from appearing. Choose a dehumidifier according to the size of your basement.
- 3). Place UV light lamps in your basement and turn them on frequently, for at least a few hours at the time. UV light is a replacement for sunlight, so it can stop the development of black mold spores. Make sure not to leave the UV lights on unattended when you are not at home.
- 4). Check the entire basement for any humidity or water sources such as water leaks in piping. Turn off and fasten dripping faucets, repair damaged piping and eliminate all other sources of water leakage.
- 5). Monitor the ventilation of combustion appliances such as heaters, stoves, furnaces and clothes dryers. Sometimes, these appliances are not properly vented and produce a higher amount of water vapor thus increasing the overall level of moisture in the basement.
- 6). Remove any firewood from the basement since it is a breeding ground for black mold. In fact, most firewood already has a small amount of mold growth before being brought inside. It is best to avoid keeping firewood in the basement altogether.
