This video is showing mold growth and staining in a split level basement ledge of the exterior wall. The basement was finished off about a year ago, with the mold and staining starting within the last two months. The owner pointed out this problem during the home inspection and asked me if I could help to figure out the cause. This wall was the only one in the basement that had this problem. All other areas were dry at the time of the home inspection.
