Water damage claims are widespread, reported most often in 15 states and by 8% of insured homeowners within the past decade. This page walks you through the key drivers of losses—burst pipes and sudden leaks, plus the way gradual leaks and maintenance issues are often excluded or limited. It also covers how water intrusion can lead to mold growth within 24–48 hours and why flood damage may require separate flood insurance.
Key Takeaways
- Water damage is the most common type of homeowners insurance claim, accounting for 18.2% of all claims

- In a survey of insured homeowners, 8% reported a water damage claim in the past 10 years
- The average homeowners insurance claim cost is $17,000 for water damage claims
- Water damage claim payout size averages $17,172 (water damage is the most expensive perils category in the referenced dataset)
- The CNBC dataset shows water damage claims average $18,000 in claim payout
- The CDC states that mold can cause health effects such as allergy and asthma symptoms
- The CDC states that people may experience symptoms including coughing and wheezing due to mold exposure
- The EPA states that mold can begin growing within 24–48 hours after water intrusion
- Many homeowners insurance policies exclude flood damage; FEMA states that flood damage is not covered under standard homeowners insurance
- FEMA states that only a separate flood insurance policy can cover flood losses
