Does homeowners insurance cover water damage in Tennessee?

It depends on where the water came from. Here is how that plays out in Tennessee and around Knoxville, and who to call at the state if your insurer stalls.

Updated 2026-11-13 · Written for homeowners, not contractors

Usually yes if the water came suddenly from inside your plumbing — a burst pipe, a split supply hose, a ruptured water heater. Usually no if it rose from outside (flood), backed up through a drain, or leaked slowly over time.

That split comes from the standard policy wording, not from a Tennessee-specific rule, so your own policy is what counts. The general rules are in our burst pipe insurance guide; this page covers the Tennessee and Knoxville layer.

Three kinds of water, three different answers

Where the water came fromStandard homeowners policyWhat covers it instead
Burst or frozen pipe, appliance, water heaterDamage generally covered; fixing the failed pipe is not—
Sewer or drain backup, sump overflowExcludedWater backup endorsement added to your policy
Creek, river or surface waterExcludedSeparate flood policy (NFIP or private)
Slow leak, seepage, mold from neglectExcludedNothing — treated as maintenance

Flood: Knoxville's creeks and the 20% discount

The city's Flood Insurance Study maps flood risk along First Creek, Third Creek and the Tennessee River; the effective maps are dated August 5, 2013. Knox County announced in December 2023 that it is updating its floodplain maps, so an address that was outside the mapped floodplain when you bought may not stay there.

Three things worth knowing:

Sewer backup: an endorsement, and a phone call

Water coming up through a floor drain or toilet is not a plumbing "discharge" under a standard policy. It is covered only if you added a water backup endorsement — check your declarations page for it today, not after the fact.

If sewage is overflowing outside or you suspect the public sewer, report it to KUB's 24-hour line at 865-524-2911, and write down when you called and what you were told.

Freeze claims after December 2022

Knoxville's average January low is 30°F, so homes here aren't built for long hard freezes. In the record cold of December 2022, KUB responded to more than 1,000 calls about frozen or broken pipes between December 23 and 29, and rolling power outages hit during the same stretch.

Freeze damage is where insurers look hardest at one question: did you take reasonable care to keep the house heated? State Farm, for example, says frozen pipe damage isn't covered if that care wasn't taken. In practice:

Claim checklist

  1. Stop the water and start drying. The EPA says to dry water-damaged areas within 24–48 hours to prevent mold.
  2. Photograph and video the source, the waterline, floors, walls and belongings before you clean up.
  3. Call your insurer or agent and get a claim number. Don't throw damaged items away yet.
  4. Keep the failed part and ask the plumber for a written note on what broke and whether it was sudden.
  5. Save every receipt for cleanup and temporary repairs.
  6. Get itemized estimates — see restoration cost in Knoxville and emergency plumber cost for what the lines should look like.
  7. Keep a log of every call: date, name, what was said.

If the claim is denied or stalls

Start with the insurer: ask for the decision in writing and for the policy language it relies on. Compare that wording with your plumber's note — "sudden" versus "long-term" is often the entire dispute.

If that goes nowhere, Tennessee has a state office for this. Consumer Insurance Services, part of the Tennessee Department of Commerce & Insurance, takes complaints about insurers:

Have your policy number, claim number, the denial letter and your call log ready. We are a referral service with no connection to any insurer or to the state, and we can't tell you how a complaint will turn out.
