Water & Excluded Perils Explainer

Step by step

1. Flood (rising surface water) is excluded from standard homeowners forms everywhere — it requires a separate NFIP or private flood policy.
2. Sewer/drain backup and sump-pump overflow are typically excluded unless a water-backup endorsement is added.
3. Groundwater seepage is typically excluded entirely, with prevention as the practical mitigation.
4. A finished basement raises the severity note on every basement water peril.

Important disclosures

1. This tool is educational only. It illustrates potential exposure using the assumptions shown — it is not insurance advice, a price, or an offer of coverage, and it does not determine whether any coverage amount is right for you. Policy language varies; review your actual policy and discuss your situation with a licensed insurance professional.
2. Exclusions and endorsement availability vary by carrier, state, and policy form — the patterns described are typical of standard homeowners forms, not a reading of your policy.
3. Flood insurance through the NFIP typically has a 30-day waiting period before it takes effect.
