Most residential mold remediation jobs run 1 to 5 days of active work on-site. Total calendar time, once you count drying, lab verification, and any reconstruction, typically stretches from a few days to several weeks. Where your job lands on that spectrum depends on the size of the affected area, how accessible it is, and whether the crew catches your moisture problem the first time around.
