The CDC suggests cleaning and drying your home after a flood 24 to 48 hours after the weather passes. Fans, dry vacs, open windows, and doors can help speed up the process.
You’ll also need to remove drywall and insulation that has been contaminated by sewage. Check for leaks in the roof as well.
If you do so happen to spot mold, put on some protective gear and clean it. Mix a cup of bleach with a gallon of water to clean off mold.
