Frozen Pipes
Usually covered if you kept the house heated. Letting it go cold or sit empty can get a claim denied.
Free to compare
What decides the claim is whether the pipe burst suddenly or had been dripping slowly inside a wall for weeks. Sudden bursts are covered water damage. Slow leaks often aren't, because insurers treat that as a maintenance problem you should have caught. If the house was left unheated, or empty for a stretch without anyone checking it, the insurer may say the freeze was foreseeable and deny the claim outright. Shut off the water, dry things out fast, and photograph everything before repairs start.
Dwelling limits and water damage endorsements vary by policy, and so does how an insurer weighs a frozen pipe against a slow leak you didn't catch. If your coverage hasn't been checked against what repairing walls, floors and a burst line would actually cost, or against how another insurer treats the same claim, that's worth knowing before the next cold snap, not after.
What to do in the first 24 hours
Shut off the water at the main valve as soon as you find the burst, then kill power to any outlets or fixtures the water reached if you can do that safely. Every hour the water keeps spreading turns a pipe claim into a flooring claim, a drywall claim, and sometimes a mold claim, and insurers look closely at whether you stopped the damage once you knew about it. Call a plumber the same day, even before the adjuster shows up. Policies generally expect you to prevent further loss, and a delay you could have avoided is one more reason a claim gets reduced or questioned.
Photograph the burst pipe itself, the water on the floor, the wet drywall, and anything the water touched, before any cleanup crew starts tearing out materials. Keep the damaged materials if you can, or at least photograph them before they're hauled away, since the adjuster may ask why a section of flooring was replaced. Write down the date you noticed the leak and the date it actually happened if they're different, because insurers ask this to figure out whether it was sudden or something that sat for a while.
Mold is where frozen pipe claims often get complicated. If standing water sits for more than a day or two, mold can start, and most policies cap what they'll pay for mold damage separately from the water damage itself, sometimes a flat dollar limit that's far less than what remediation actually costs. A fast, documented cleanup is the best way to keep a water claim from turning into a mold dispute. If a contractor mentions mold during cleanup, get that noted in writing right away rather than after the fact.
Sewer and drain backups from the same cold snap are usually a different coverage line entirely. A frozen or blocked sewer line that backs water into the house typically isn't covered unless the policy has a sewer backup endorsement added separately, and dwelling or water damage coverage alone won't apply. If water entered from outside the house, from a flooded yard or rising groundwater rather than from a pipe inside, that's flood damage, which a standard homeowners policy never covers regardless of how the water got there. Check the declarations page for both endorsements before assuming either is included.
What repairs does the claim actually pay for
Dwelling coverage pays to repair the physical damage. That means the burst section of pipe, the drywall that got cut out, the flooring that warped from standing water. It does not pay to upgrade the plumbing beyond what was there before. If the house had old galvanized pipe that froze and split, the insurer replaces that section, not the whole system, unless a separate endorsement for code upgrades or full replacement is on the policy.
Water that caused the damage is covered under the dwelling or personal property sections, but tracking down the source isn't always included. Some policies pay to open a wall to find the leak, then pay again to close it back up once the plumber confirms what broke. Others only cover the opening if the cause turns out to be a covered peril. This is one of those details that sits in the policy wording rather than the declarations page, so it's worth reading the water damage section itself rather than assuming.
Personal property, meaning furniture, rugs, electronics, anything the water ruined, is handled separately from the structure and usually has its own limit. If a finished basement flooded from the burst pipe and ruined a couch, a television and boxes of stored items, those get valued and paid out against the personal property limit, which is typically a percentage of the dwelling limit. Replacement cost coverage pays what a new item costs. Actual cash value coverage subtracts depreciation first, so a ten-year-old couch pays out at what a ten-year-old couch is worth, not what a new one costs.
The deductible applies once per claim, not per room or per type of damage. A single frozen pipe that ruins a ceiling, a wall and a floor is one claim with one deductible, even though three different trades end up doing the repair. Where the costs get large is when the repair opens up finished space, like cutting into a ceiling to reach a pipe in a wall cavity above it. That reconstruction cost counts toward the dwelling limit, and it adds up faster than the plumbing repair itself does.
Before the next freeze
Find the water main shutoff now, before you need it in a hurry. Then check your declarations page for a sewer backup endorsement and your dwelling limit against what rebuilding a wall or ceiling would actually cost.
