Storm-driven flooding is Category 3 black water — river water, storm surge, and overland flow carrying sewage, chemicals, and debris. That puts mitigation at roughly $7–$7.50+ per sq ft (RestoreAdvisor 2026), with typical single-home jobs running $3,000–$10,000+. The other shock: standard homeowners policies do not cover flooding — that's a separate flood policy (NFIP or private).

Cost breakdown

Scope	Typical range	Notes
Mitigation (black water protocol)	$7–$7.50+ per sq ft	Full PPE, containment, disposal of everything porous the floodwater touched.
Typical single-home job	$3,000–$10,000+	Scales with flood depth and how long water stood.
Content pack-out & cleaning	$1,000–$5,000+	Salvageable belongings cleaned off-site; the rest documented for the claim.
Flood insurance deductible	NFIP typically $1,000–$10,000	You choose it at policy purchase — higher deductible, lower premium.

What moves the price

• Flood depth — inches vs. feet changes everything about the scope
• How long the water stood before receding and drying started
• Contamination level — storm surge and river flooding are always Category 3
• Whether the foundation, electrical, or HVAC systems were submerged
• Mold growth in wall cavities if drying was delayed past 48 hours
