Stop Mold Spreads in Home

Airborne mold spores take root in spaces containing moisture

Mold needs moisture to grow and spread. So, if you have mold in your basement--unless there are leaks in your home's envelope--that doesn't necessarily mean that there is mold anywhere else in the house. The spores from basement mold can travel throughout a house on airflows, but they are just part of house dust and cannot grow into colonies unless there is dampness present. That does not mean, however, that there is no reason for concern, because mold spores can cause symptoms in those who are sensitized.
