Are Frozen Pipes Covered by Home Insurance?
Usually yes, if you kept the house heated and took reasonable steps to prevent freezing. Neglect can get the claim denied.

How the pipe froze
A burst pipe from a cold snap is covered as sudden water damage. But if the insurer finds the house was left unheated, a door propped open, or a known draft ignored, that gets read as neglect and the claim can be denied.
Reasonable care standard
Insurers expect you to keep the house heated through winter and know where your main water shutoff is. If you travel, that might mean leaving heat on at a minimum temperature or having someone check the house. Your policy may define this explicitly.
What the water ruined
The pipe itself is usually a small cost next to what it floods. Flooring, drywall, ceilings below, and belongings in the path of the water typically fall under dwelling and personal property coverage, up to your policy's limits.
Documenting it fast
Shut off the water, take photos before cleanup starts, and keep receipts for any emergency repairs. Insurers can question a claim reported weeks late or one where damage was fixed before they could see it.
What your policy actually pays depends on its dwelling limit and how your insurer weighs the neglect question, and those terms vary a lot between companies. Some are stricter about unheated periods or stretch coverage further on the cleanup side. Comparing policies now, before anything freezes, shows what you'd actually collect and where the gaps sit.
What about mold that shows up afterward
Mold that grows because a pipe burst and nobody found it for a few hours is normally covered along with the rest of the water damage. It's treated as a direct result of a sudden event. Mold that's been building for months because of a slow, hidden leak is a different story. Most policies cap mold cleanup at a low amount, often a few thousand dollars, separate from the main dwelling limit. Some exclude it outright if the insurer decides it grew because of neglect rather than a sudden accident.
The line between the two often comes down to how fast the leak was found and dealt with. A pipe that bursts and floods a kitchen in an afternoon reads as sudden. Water seeping behind a wall for weeks before anyone notices reads as something that should have been caught sooner. An adjuster looking at mold damage will usually ask how long the moisture was there. That's part of why cutting out wet drywall and taking photos right away matters even when the visible damage looks minor.
Sewer backup is a separate problem from a frozen pipe, but it comes up in the same conversations because both involve water where it shouldn't be. A standard policy does not cover water that backs up through a drain or sewer line, whether that's from a clog, tree roots, or a municipal system overwhelmed by heavy rain. Many insurers sell sewer backup coverage as an endorsement, usually inexpensive relative to what it protects. It's worth checking whether a policy includes it or treats it as an add-on.
Flood is excluded from every standard homeowners policy regardless of cause, and that matters here because a burst pipe and a flood can look similar once a room is underwater. Insurers draw the line based on where the water came from. Water from a pipe inside the house is a covered peril if the freeze itself wasn't caused by neglect. Water that enters from outside, like a river overflowing or storm surge, falls under a separate flood policy through the National Flood Insurance Program or a private flood insurer. A homeowner dealing with water damage after a storm should know which category an insurer will assign it to before assuming either way.

Many insurers sell sewer backup coverage as an endorsement, usually inexpensive relative to what it protects, so it's worth checking whether a policy already includes it or treats it as an add-on.

Check your declarations page for your dwelling limit, whether sewer backup coverage is included, and the mold cleanup cap. Knowing those numbers before a pipe bursts tells you what the policy actually covers.
