River overflow. Storm surge. Sewer backup. Roof failure during a hurricane. The water that floods a home from outside isn't the water that came out of your tap last Tuesday — it's contaminated, often with sewage, soil pathogens, fuel, agricultural runoff, and biological waste. Treating a flood like a normal water spill is how families end up sick and how insurance claims get denied. Our dispatch network includes contractors trained specifically in Category 3 (black water) remediation — the highest contamination tier in the IICRC standard.
The restoration industry classifies water damage in three categories based on contamination level. Flood water from outside almost always falls into the most severe category — and that changes everything about how the job is handled.
Category 1 — Clean Water: Comes from a sanitary source. Burst supply line, overflowing sink, melting ice. Safe to handle. Materials usually salvageable if dried within 24 hours.
Category 2 — Gray Water: Significantly contaminated. Dishwasher discharge, washing machine overflow, toilet bowl water without solids. Carries microorganisms that can cause illness.
Category 3 — Black Water: Grossly contaminated. Sewage, river water, ground surface water from natural events, water that's been sitting more than 48 hours and grown its own microbiome. This is what flood water is. It carries pathogens, parasites, and toxins that require full PPE, hazmat-grade containment, and disposal of all porous materials it touched.
A contractor who treats Category 3 water like Category 1 isn't saving you money — they're setting up a much bigger problem six months later, and likely voiding your insurance coverage in the process.
Cutting corners on flood cleanup creates worse problems than the flood itself. Here's the protocol professional contractors follow.
Before anything else: power shut-off verification, gas line check, structural assessment for collapse risk. Nobody enters until the building is safe to enter.
Contaminated water is pumped out using equipment dedicated to Category 3 work — never reused on clean-water jobs. Disposal goes to permitted facilities only.
Every item is documented — what's salvageable (solid wood, ceramics, metals), what's not (upholstered furniture, mattresses, particleboard, drywall up to flood line + 12 inches).
Saturated drywall, insulation, carpet, padding, and trim are cut out and bagged as biohazard waste. This is unavoidable in true flood losses — porous materials cannot be decontaminated.
Every remaining surface — studs, subfloor, concrete — is cleaned mechanically and treated with EPA-registered antimicrobials. Two-stage application is standard.
Industrial dehumidification runs for the duration. Final clearance is confirmed with moisture readings AND microbial sampling before reconstruction can begin.
Common reactions that make flood damage worse — and what to do instead.
Generally, no. Standard homeowners policies in the U.S. exclude damage caused by rising water, storm surge, and overland flooding. That coverage requires a separate flood insurance policy, usually through the National Flood Insurance Program (NFIP) or a private flood insurer. Sewer backup is sometimes covered under a homeowners endorsement but not always.
If you're not sure what you have, call your agent before mitigation begins — but don't delay starting cleanup waiting for an answer. Mitigation is your responsibility regardless of coverage status.
FEMA disaster assistance is available in federally declared disaster areas — application opens at DisasterAssistance.gov. The SBA offers low-interest disaster loans to homeowners and renters even if you don't own a business. Some state programs supplement federal aid. The contractor you're matched with through our dispatch can usually direct you to the right local resources, since they work disaster zones regularly.
It depends on the material. Solid wood, glass, ceramics, hard plastics, and most metals can be cleaned and decontaminated. Upholstered furniture, mattresses, pillows, particleboard furniture, soft toys, and most electronics that contacted Category 3 water are typically total losses — they can't be reliably decontaminated and pose ongoing health risks. Photographs, important documents, and irreplaceable items can sometimes be salvaged through specialty document drying services.
More than most people realize. Flood water routinely contains E. coli, hepatitis A, leptospirosis, tetanus exposure, and a long list of bacteria that cause gastrointestinal illness, skin infections, and respiratory issues. Children, elderly residents, anyone immunocompromised, and pregnant women face elevated risk. Flood water also commonly carries fuel, pesticides, fertilizers, and industrial runoff in agricultural and industrial areas. Always treat standing flood water as a serious biohazard.
From dispatch to fully reconstructed, a typical residential flood loss runs three to six weeks. Cleanup and drying take roughly one to two weeks; reconstruction (drywall, flooring, paint) takes another two to four weeks. Severe losses involving structural damage, well or septic contamination, or HVAC replacement can stretch significantly longer. Your contractor will give you a realistic timeline once the assessment is complete.
If your area is under a federal disaster declaration AND you have flood insurance, file both — FEMA assistance can cover gaps in insurance coverage but won't duplicate it. Document everything from day one: photos, receipts, written communications. The contractor handling your job will provide a detailed scope of work that supports both claim types.
Our 24/7 dispatchers will connect you to a vetted local contractor in minutes. No upfront cost to you — most major insurance carriers accepted by our network partners.
