“Mold possibly starts after 72 hours. So you have 72 hours to get that drying close to done,” he said.

Martinez said sump pumps are to blame for most basement floods. Sump pumps are better, he said, but they only last for six years. Martinez said some homeowners keep their pumps for as long as 20 years.
