Start with conditions, not a product
Visible growth is only part of the problem. A durable plan addresses water entry, humidity, material condition, containment, and post-work verification.

Warren context
Warren's housing stock filled in fast around the Detroit Arsenal Tank Plant, which opened in 1941, and the General Motors Technical Center that GM built out from 1949 to 1956, leaving a dense band of 1950s-60s ranch houses and brick bungalows sitting on the flat, poorly draining clay soils of the old glacial Lake Warren plain. Because Warren's sanitary sewers were engineered around a roughly two-inch-rainfall standard and footing drains tie into those same sewers, heavier modern storms regularly back up into basements -- and a basement that stays damp for even a day or two after a backup is exactly the kind of hidden moisture that turns into a mold problem in homes built before modern vapor barriers and sump systems were standard.
