Cost by water category
The restoration industry classifies water into three categories, and they price very differently:
- Clean water (Category 1) — from a supply line, faucet, or rainwater. Cheapest to handle; mostly extraction and drying. Often a few hundred to roughly $2,500 for a contained area.
- Gray water (Category 2) — from dishwashers, washing machines, or shower drains. Contains some contaminants, so more sanitizing and sometimes material removal. Commonly $2,000–$4,500.
- Black water (Category 3) — sewage, river flooding, or any water that sat long enough to grow bacteria. The most expensive: full PPE, demolition of porous materials, and heavy disinfection push this from roughly $4,000 well into five figures.
Cost by affected area
Restoration is largely a function of square footage and the number of rooms involved, because equipment, labor, and the volume of material to dry or remove all scale with it. A single bathroom or closet is at the low end; a flooded finished basement — with carpet, drywall, and contents — is at the high end. Multi-level losses, where water travels down through ceilings, add structural drying on every floor it touches.
What drives the bill up
- Time before mitigation — the single biggest lever. Drying salvageable material is far cheaper than tearing it out and rebuilding.
- Hidden moisture — water behind walls and under floors needs moisture mapping and longer drying; missed pockets cause mold later.
- Materials affected — hardwood, plaster, and built-in cabinetry cost more to dry or replace than vinyl and laminate.
- Mold remediation — if mold has already set in, that's a separate, added scope.
- Reconstruction — extraction and drying are mitigation; the repair phase that rebuilds drywall, flooring, and paint afterward is often priced separately.
The insurance angle
Many homeowners are surprised by how much of this insurance covers. Standard homeowners policies generally pay for sudden and accidental water damage — a pipe bursts, a water heater fails, an appliance hose lets go. What they typically exclude is gradual damage (a slow leak you should have caught), damage from lack of maintenance, and flooding from outside, which requires a separate flood policy (NFIP or private). Most policies also have a duty to mitigate — you're expected to stop the damage from getting worse, which is one reason fast professional drying helps both your home and your claim.
