Last updated: October 2026 · Cost figures are national reference ranges from published industry sources, not quotes.

Whether insurance pays for water damage comes down to one question: was it sudden and accidental, or gradual? Burst pipes and appliance failures are typically covered (PuroClean 2026). Slow leaks, maintenance neglect, groundwater seepage, and flooding from outside the home are typically not covered without separate endorsements or flood insurance. Here's how to file a claim that actually gets paid.

Cost breakdown

Scope	Typical range	Notes
Typical covered event	burst pipe, appliance failure	Sudden and accidental — the magic words in most policies.
Sewer backup endorsement	often $40–$100/yr add-on	Standard policies exclude it; the rider is cheap compared to a $10,000 cleanup.
Flood insurance (NFIP)	separate policy required	Standard homeowners policies never cover overland flooding.
Mold coverage cap	commonly $1,000–$10,000	Many policies cap mold remediation separately — check yours before you need it.

What moves the price

• Document everything immediately — photos and video before cleanup starts
• Mitigate further damage (insurers require it; don't let it sit while you wait)
• Keep every receipt — emergency mitigation, hotel, meals may be reimbursable
• Get the adjuster out fast, but get your own contractor quotes too
• Never admit the leak 'has been going on a while' — gradual damage is the #1 denial reason
