Given the proper conditions, mold will start to germinate and grow as early as 24 hours after encountering the moisture source. In 3 to 12 days, the mold spores will colonize. In 18-21 days, the mold can become visible. In general, the longer that moisture is present, the greater the chance for mold to grow and spread.
The Timeline of Mold Growth on Water-Damaged Drywall
Mold grows best in warm, dark areas with high levels of humidity and a food source (in this case cellulose). When these conditions are met and moisture is present, then spores will germinate and become visible within 48-72 hours after initial contact with water.
The Environmental Protection Agency (EPA) and the Centers for Disease Control and Prevention (CDC) say so. A single water leak can quickly lead to mold if not fixed right away.
