mold growth timeline

Black mold can begin growing within 24–48 hours of water damage when temperatures are warm, materials are organic, and humidity exceeds 60% — conditions that develop quickly in a Los Angeles home after a burst pipe or slow leak. This guide covers the growth timeline, what factors accelerate it, how mold spreads through wall cavities and HVAC systems, and the IICRC-certified remediation process.
