Flood Cleanup Labor Hours Calculator
Estimate the total labor hours required to clean up after a flood based on the affected area, water depth, damage severity, and number of workers.
Affected Floor Area (sq ft)
Standing Water Depth (inches)
Damage Level
-- Select Damage Level -- Light – Surface moisture, no structural damage Moderate – Soaked materials, some drywall/flooring damage Severe – Structural damage, mold risk, debris present Catastrophic – Major structural loss, heavy contamination
Contents Removal Required?
No – Empty space or contents already removed Yes – Furniture, appliances, personal items present
Mold Remediation Required?
No Yes
Number of Workers in Crew

#### Formula
Base Hours = (Area ÷ 200) × Depth Factor × Damage Factor
Depth Factor = 1 + (Depthinches ÷ 12) × 0.35
Contents Hours = Area × 0.05 (if contents removal required)
Mold Hours = Area × 0.08 (if mold remediation required)
Total Labor Hours = Base Hours + Contents Hours + Mold Hours
Calendar Days = Total Labor Hours ÷ (Crew Size × 8)
Cost Range = Total Labor Hours × $35 to $65 per hour
Damage LevelFactorDescription Light1.0×Surface moisture only Moderate1.5×Soaked materials, minor structural Severe2.2×Structural damage, mold risk Catastrophic3.0×Major structural loss, contamination
#### Assumptions & References
- Base productivity of 200 sq ft per labor-hour covers water extraction, drying equipment setup, and basic debris removal under light-damage conditions with no standing water.
- Each additional foot of standing water increases labor effort by 35%, accounting for pumping time, saturated materials, and safety precautions (FEMA P-55, Residential Coastal Construction).
- Contents removal adds 0.05 labor-hours per sq ft based on industry estimates for moving, sorting, and disposing of household items.
- Mold remediation adds 0.08 labor-hours per sq ft per EPA mold remediation guidelines (EPA 402-K-02-003).
- Labor cost range of $35–$65 per hour reflects U.S. national averages for restoration technicians (BLS Occupational Employment Statistics, 2023).
- Calendar days assume 8-hour work shifts with no overtime.
