After a Flood in LA: A 24-Hour Action Checklist

The first 24 hours after flood water enters your Los Angeles home determine almost every outcome that follows. Insurance claim quality, mold prevention, and recovery cost all hinge on what you do today.

Hour 0–1: Safety first

If water is still rising, leave. If electrical panels are wet or you smell gas, leave. Standing water in a house with active electrical service is genuinely lethal. Wait for power to be cut at the meter before re-entering. Ready.gov flood guidance covers the safety checklist in detail.

Hour 1–3: Documentation

Before you move anything, photograph every room from multiple angles. Video the standing water level on walls. Photograph damaged contents in their original positions. This is your insurance evidence package. Time-stamped phone photos are admissible.

Hour 3–6: Extraction

If you can pump or bail water out safely, do it. Otherwise wait for a restoration crew. Pumping water onto saturated ground outside doesn't move the problem — it cycles. Discharge needs to go to storm drains if accessible.

Hour 6–12: Remove porous materials

Anything porous that sat in flood water is contaminated. Carpet, padding, insulation, drywall up to two feet above the water line, particleboard, upholstered furniture. These come out and go to the curb. California waste rules require certain materials be tagged for disposal — check with your local sanitation district.

Hour 12–24: Begin drying

Industrial air movers, dehumidifiers, and antimicrobial treatment within 24 hours of flooding is the EPA-recommended mold prevention window. Restoration crews like have this scope as standard. After 48 hours mold is established and remediation scope grows substantially.
