Flood cleanup costs $2,500–$15,000. Water depth, duration, and contamination level drive the range.
Flood cleanup is a multi-phase process: pump-out of standing water, extraction, structural drying, sanitization, and mold prevention. Each phase adds cost, and the faster you start, the less expensive the total job. Contractors available 24/7 for emergency response.
Call for Emergency Response — 24/7Flood cleanup costs $2,500–$15,000 for most residential jobs. That range is driven by three factors: how deep the water was (inches vs. feet), how long it sat before extraction began (hours vs. days), and what category the water is (clean supply line water vs. stormwater mixed with sewage). Getting a contractor on-site within the first few hours is the single most effective way to limit the total cost.
Flood cleanup cost by scenario
| Scenario | Typical Scope | Estimated Cost |
|---|---|---|
| Minor basement flooding — clean water, under 2 inches | Wet vac extraction, drying, mold prevention | $1,500–$4,000 |
| Flooded basement — clean water, 6–12 inches | Pump-out, full structural drying, content removal | $3,000–$7,000 |
| Multiple rooms — stormwater (Category 2/3) | Contaminated water protocol, full sanitization | $6,000–$15,000 |
| Full home flood — 1–3 feet standing water | Industrial pump-out, full structural assessment | $10,000–$30,000 |
| Sewage backup | Category 3 protocol, hazmat handling | $4,000–$12,000 |
The five phases of flood cleanup
1. Water removal. Pump-out of standing water using submersible pumps, followed by extraction of water absorbed into carpet, padding, and subfloors using truck-mounted extractors. The pump handles standing water; the extractor handles absorbed water. Both must complete before drying begins.
2. Structural drying. Industrial dehumidifiers and air movers run continuously for 3–7 days, targeting the dew point of affected materials. Contractors place moisture meters in walls, under flooring, and in structural members and monitor readings daily. A job is not dry until every meter reads at or below the target moisture content — not when the surface looks and feels dry.
3. Sanitization. Any surface that contacted Category 2 or Category 3 water receives antimicrobial treatment. Porous materials (drywall, insulation, carpet) that cannot be adequately sanitized are removed rather than treated. Hard surfaces are wiped with EPA-registered antimicrobials and allowed to dry under the dehumidification system.
4. Content handling. Furniture, belongings, and documents are inventoried, assessed for salvageability, and either moved off-site for professional cleaning or documented as unsalvageable for insurance purposes.
5. Mold prevention. Antimicrobial treatment applied to all structural surfaces before reconstruction begins. The drying phase prevents mold from starting; the mold prevention treatment addresses any spores that were present before the flood.
Flood Cleanup Questions
Flood cleanup, answered
$2,500–$15,000 for most residential jobs. A minor basement flood with clean water and quick response typically runs $3,000–$6,000. Major flooding with stormwater contamination across multiple rooms runs $6,000–$15,000 before any structural repairs. Full home flooding from a hurricane or major storm event can reach $20,000–$60,000 depending on depth and duration of standing water.
Extraction and initial setup takes 1 day. Structural drying runs 3–7 days depending on the extent of water penetration, the materials affected, and the humidity of the outdoor air. Sanitization and content handling typically add 1–2 days after drying is complete. The full cleanup phase (before any reconstruction begins) is usually 5–10 days. High-humidity climates like Houston and Atlanta extend drying time versus drier markets.
For minor clean-water events (under 1 inch, caught quickly, no contamination), DIY cleanup with a wet vac and household fans may be adequate. For anything larger, professional equipment makes a meaningful difference: a truck-mounted extractor removes 10–20x more water from carpet and subfloor than a rental wet vac, and industrial dehumidifiers move far more moisture than household units. The risk with DIY is missing moisture in wall cavities and subfloors that leads to mold 2–4 weeks later — by which point the cost of remediation has increased significantly.
