The very best way to reduce your risk of a moldy basement is to have a dry basement. That means installing a waterproofing system, minimizing the impact of plumbing leaks, and reducing the overall relative humidity. In some cases, it will take all three processes in order to reduce mold risk. It's especially true here in Evansville because we do have an outdoor humidity that increases our indoor relative humidity. We recommend looking for a quality dehumidifier and offer the SaniDry upright dehumidifier, which is EnergyStar rated and is a dehumidifying powerhouse!
