The Real Cost of Flooding

What does flooding actually cost? Minor floods run $10K–$50K. Severe floods top $200K. And standard homeowners insurance covers none of it. The prevention math shows a $40 barrier beats a $20,000 claim.

What Standard Homeowners Insurance Won’t Cover
Standard homeowners policies exclude flood damage entirely. You are also typically NOT covered for:
  • Flood-related mold remediation
  • Foundation damage from hydrostatic pressure
  • Temporary housing during repairs
  • Vehicle flood damage (requires comprehensive auto)
  • Landscaping, fences, pools, and exterior hardscaping
  • Basement improvements and finished space (often excluded even in flood policies)

📏
The 1-Inch Rule
Just 1 inch of water in your home causes an average of $25,000 in damage according to FEMA and NFIP claims data. A standard NFIP flood policy costs ~$800/year. That means a single small flood event costs more than 31 years of premiums.
