The 24–72 hour window
When porous materials stay wet, mold can begin to develop within roughly 24–72 hours. The faster materials are dried, the lower the chance of established growth.
Hidden moisture behind walls and under floors is the biggest risk.
Common sources in Colorado
Frozen and burst pipes during cold snaps, appliance leaks, roof leaks, and snowmelt intrusion are frequent water-damage sources in mountain homes.
What to do
Stop the source, remove standing water, and get a professional evaluation that includes moisture mapping. If growth is found, remediation may be appropriate.
