- Cut power at the panel if water is near electrical: Only if you can safely reach the panel without stepping through water.
- Document with photos and video before any cleanup: Required for insurance claims.
- Call your insurer within 24 hours: Report claim, request adjuster visit.
- Call 311 to report the event: Creates a documented record for future rebate eligibility and emergency assistance programs.
- Engage IICRC-certified restoration company: Drying must begin within 24–48 hours to prevent mold. Look for IICRC certification at iicrc.org/find-a-pro.
