Flood Cleanup Checklist After Heavy Rain

After a flood event — whether from a creek overflow, sustained rainfall, or storm surge — the first 12 hours determine the size of the cleanup. Here is the checklist crews use on every flood call, adapted for homeowners to follow before crews arrive.

Step 1 — Confirm safety before re-entering (immediate)

• Electrical: Do not enter standing water until the main electrical breaker is off. If the panel is in the affected area, call your utility company to shut off service at the meter.
• Gas: If you smell gas, leave immediately and call the gas company from outside. Do not flip switches.
• Structural: Look for sagging ceilings, cracked walls, or shifted foundations. If anything looks compromised, do not enter until a contractor or building inspector clears it.
• Water classification: Flood water from outside is Category 3 by definition. Assume it carries sewage, chemicals, and contaminants. Wear rubber boots, gloves, and a P100 respirator if you must enter.

Step 2 — Document before you touch anything

• Photograph every affected room from multiple angles before moving items
• Photograph water lines on walls and exterior siding
• Photograph damaged contents in place
• Note the time water entered and how high it reached in each room
• Save weather alerts and news coverage showing the storm event — useful for the insurance claim

This documentation is what your adjuster will rely on. Photos taken after cleanup are worth a fraction of photos taken at peak damage.

Step 3 — Get standing water out

If standing water is more than a couple inches deep or has been sitting for hours, household equipment will not be effective. Truck-mounted extractors pull water out of carpet pad, subfloor, and wall cavities at a rate household equipment cannot match.

For surface water, sump pumps, wet/dry vacuums, and squeegees can move water toward floor drains or outside. Do not pour contaminated flood water down sinks or toilets if you suspect the municipal sewer is overwhelmed (common during regional flood events in Houston, Memphis, St. Louis, and Kansas City).

Step 4 — Triage contents

Decide what to discard, what to try to clean, and what to set aside for professional cleaning:

• Discard: upholstered furniture, mattresses, pillows, stuffed animals, paper documents, food (including sealed containers in the affected area), wet drywall, wet insulation, particle-board furniture
• Clean and salvage if possible: sealed wood furniture, glass, ceramic, metal, hardwood floors if the finish is intact, sealed concrete
• Set aside for assessment: photographs, artwork, electronics (do not power on), heirlooms — specialists can sometimes restore these

For sealed cardboard boxes of paper documents, the contents are usually salvageable if they can be dried within 48 hours. Spread papers single-layer in a dry area; do not heat them.

Step 5 — Call for professional dispatch

For any flood event that reached more than one room or sat for more than a few hours, professional flood damage restoration is appropriate. Crews arrive with truck-mounted extractors, structural drying equipment sized to the affected cubic footage, antimicrobial products specifically registered for Cat 3 water, and the IICRC S500 documentation needed for your insurance claim.

Call (888) 508-0998. Typical dispatch in flood-impacted areas runs 60–120 minutes during regional events because call volume spikes; we pre-stage crews when major rain is forecast in metros like Sacramento and the Mississippi River corridor.

Step 6 — Open your flood insurance claim

Flood from rising surface water is not covered by standard homeowners insurance. You need a separate flood policy through NFIP or a private flood carrier. If you have one:

• Call your flood policy administrator (not your homeowners carrier — they are usually different)
• Open the claim with the loss date and rough scope
• Take notes on what your adjuster says about documentation requirements
• Keep all receipts for emergency supplies, temporary housing, and discarded items

Wind-driven rain through storm-damaged roof or windows is usually covered under homeowners (not flood). If you have both flood and homeowners losses from the same storm, you may need to file with both carriers.

Step 7 — What the cleanup process looks like

Once crews arrive: containment is set up to isolate the affected area; standing water is extracted; porous materials contacted by Cat 3 water are removed (drywall, insulation, carpet pad, often subfloor); antimicrobial application; air movers and dehumidifiers run continuously for 5–10 days; daily moisture readings verify drying; verified clearance before reconstruction begins.

Total timeline: 5–14 days mitigation, 3–8 weeks reconstruction depending on scope.

What to avoid

• Do not run forced-air HVAC over Cat 3 water — it spreads contaminants
• Do not save soaked porous materials — they cannot be effectively decontaminated
• Do not delay calling for dispatch hoping the damage will dry on its own
• Do not throw out documentation or photographs before insurance assessment
• Do not pay deductible to a crew before the adjuster has reviewed the scope

FAQ

How long do I have to start cleanup?

Mold growth begins at 24–48 hours. Drying should begin as soon as standing water is out, ideally within 12 hours of the event. Delayed mitigation can void coverage if the carrier can show the homeowner failed to mitigate.

Can I use household bleach for flood cleanup?

Household bleach is not appropriate for Cat 3 flood water. EPA-registered antimicrobials specifically designed for sewage and flood contamination are required. Bleach also fails to penetrate porous materials and damages many surfaces.

Will FEMA help me?

Federal assistance programs activate after major declared disasters. If your county is included in a federal disaster declaration, FEMA Individual Assistance can provide grants for uninsured losses. Apply at disasterassistance.gov.

Do you handle flood cleanup in cities along the Mississippi?

Yes. Memphis, St. Louis, and the broader Mississippi River corridor are part of our regular service area. We pre-stage crews when river-flood watches are active.
