Quick answer: Usually yes, for the sudden water damage a frozen pipe causes when it bursts, minus your deductible. The standard HO-3 excludes freezing damage while the home is vacant, unoccupied or under construction unless you used reasonable care to keep the heat on or shut off the water and drain the system. The policy generally pays to tear out and replace walls or floors to reach the broken pipe, but not to replace the failed pipe itself in many cases, and it excludes slow leaks that went on for weeks.
When temperatures drop well below freezing, water in exposed pipes can freeze, expand and split the pipe. The damage often shows up only when the ice thaws and water pours into a ceiling, wall or basement. By then the claim question is not whether there is damage but whether the policy will pay for it.
The answer depends mostly on one condition in the policy: whether you took reasonable care to keep the house heated. This article explains that rule using the Insurance Services Office (ISO) Homeowners 3 Special Form, the model most U.S. insurers base their policies on. For the overall structure of coverage, see our homeowners insurance guide.

Policies differ by insurer and state. This is general information, not insurance advice. Read your own policy.
How the Policy Treats Frozen Pipe Damage
The dwelling part of a standard HO-3 is open perils, so sudden water damage to the house is covered unless an exclusion applies. Water that escapes from a plumbing system that froze and burst fits the general coverage. Your belongings are covered under named perils, and the list includes both “freezing of a plumbing, heating, air conditioning or automatic fire protective sprinkler system or of a household appliance” and “sudden and accidental discharge or overflow of water or steam” from those systems.
That means a burst pipe in an occupied home during a cold snap is usually a covered claim for:
- Damaged drywall, ceilings, flooring, cabinets and insulation.
- Damaged furniture, electronics, clothing and other belongings.
- Water extraction and drying.
- Additional living expenses if the house is unlivable while repairs are made.
The deductible applies once per occurrence. If you have a high or percentage deductible, a small leak may not be worth claiming.
The Freezing Exclusion and the Reasonable-Care Rule
The key limitation is written into both the dwelling and personal property sections. The ISO form excludes freezing damage to plumbing, heating, air conditioning, sprinkler systems and household appliances, and the resulting discharge of water, while the dwelling is vacant, unoccupied or being constructed, unless you have used reasonable care to:
- Maintain heat in the building, or
- Shut off the water supply and drain all systems and appliances of water.
Two terms in that rule matter. Unoccupied means nobody is living there right now, such as during a two-week holiday trip. Vacant means the house is empty of people and the personal property needed to live there, such as a house between owners. Both trigger the condition.
If you leave for a winter vacation with the thermostat set at a reasonable temperature and the furnace fails, the insurer will look at whether you used reasonable care. Insurers commonly ask about thermostat settings, furnace maintenance and whether someone checked the house. If you turn the heat off to save money and leave the water on, the claim is likely to be denied.
Some states and policies add specific requirements, such as a temperature or inspection frequency. Read your form, and if you plan a long absence, ask your insurer what it expects.
For long empty periods, a separate rule kicks in. Many policies reduce or remove coverage for certain perils after the home has been vacant more than 60 consecutive days. Our guide to vacant home insurance explains those limits.
What Gets Paid and What Does Not
Even when a burst pipe claim is covered, not every cost is paid.
| Cost | Usually covered? |
|---|---|
| Water damage to walls, floors, ceilings and cabinets | Yes, minus deductible |
| Water damage to furniture and belongings | Yes, under personal property |
| Tearing out a wall or floor to reach the broken pipe | Yes, under the ISO water damage provision |
| Replacing the split pipe or failed appliance itself | Often no, under the ISO form |
| Mold that develops after a prompt repair | Depends on policy and any mold limit |
| Damage from a slow leak over weeks or months | Generally excluded |
| Water that backed up from a sewer or drain | Only with water backup coverage |
| Flooding from outside water | Excluded; needs flood insurance |
The ISO form specifically covers the cost to tear out and replace any part of the building needed to repair the system or appliance from which the water escaped. It does not cover loss to the system or appliance itself. In practice, that means the plumber’s bill for replacing a section of cracked pipe is often your expense, while the wall around it and the water damage are covered.
Mold deserves a note of its own. Many policies limit or exclude mold, while some cover it when it results from a covered water loss and is promptly addressed. Our article on whether homeowners insurance covers mold explains the common limits.
Gradual Leaks Are a Different Claim
Not every frozen pipe bursts dramatically. Some develop a small crack that drips inside a wall for weeks before anyone notices.
The ISO form excludes damage from continuous or repeated seepage or leakage of water or steam over a period of weeks, months or years. If the adjuster finds rot, staining and mold that show a long-running leak, the claim may be denied or reduced even if the leak started with freezing.
That is a good reason to check basements, crawl spaces and under-sink cabinets after a cold snap. Catching a small leak early protects both your house and your claim.
Burst Pipe, Sewer Backup or Flood?
The source of the water decides which coverage applies, and winter produces all three. A pipe that bursts inside your walls is a plumbing discharge, which the base policy addresses. Water that comes up through a floor drain or toilet because a frozen or overloaded sewer line backed up is a different peril. The standard HO-3 excludes water that backs up through sewers or drains, or overflows from a sump pump, and that gap is filled only by an endorsement. Our explainer on water backup coverage for sewers and sump pumps shows how those endorsements are priced and limited.
Snowmelt and ice-jam flooding that enters from outside is flood, excluded under homeowners policies and covered only by a flood policy through the National Flood Insurance Program or a private insurer.
Will a Burst Pipe Claim Raise Your Premium?
Water claims are among the claims insurers watch most closely, because a home with one water loss is often seen as more likely to have another. A single claim may or may not change your rate, depending on your insurer and state rules, but several water claims in a few years can lead to a surcharge or a non-renewal. That is one more reason to weigh small losses against your deductible and to fix the cause of a leak promptly.
Renters and Condo Owners
Renters. A renters policy covers your belongings when a pipe bursts, along with liability and additional living expenses. The building itself is the landlord’s responsibility. If a frozen pipe in your unit damages a neighbor’s apartment, liability questions depend on who was at fault, for instance whether you turned off the heat.
Condo owners. Damage is often split between the association’s master policy and your HO-6 unit-owner policy, depending on your bylaws. Pipes inside your walls may be yours, while common risers belong to the association. The master policy’s deductible may also be charged back to the owner whose unit caused the loss. Read your condominium documents before winter.
How to Prevent Frozen Pipes
The American Red Cross publishes practical winter steps that also strengthen any claim you might need to file:
- Keep the heat on day and night during cold weather. If you will be away, the Red Cross recommends setting the thermostat no lower than 55 degrees Fahrenheit.
- Open kitchen and bathroom cabinet doors so warmer air reaches pipes on exterior walls.
- Let cold water drip from faucets served by exposed pipes during extreme cold. Moving water is less likely to freeze.
- Disconnect and drain garden hoses and shut off and drain outdoor spigots before winter.
- Insulate pipes in unheated areas such as attics, crawl spaces, garages and basements, using pipe sleeves or heat tape rated for the job.
- Seal gaps around pipes where cold air enters.
- Keep the garage door closed if water lines run through the garage.
- Know where your main shutoff valve is, and make sure everyone in the house does too.
If you travel, ask someone to check the house regularly. Smart thermostats and water leak sensors that alert your phone can catch a furnace failure or leak early, and some insurers offer discounts for leak detection devices.
If Your Pipes Freeze or Burst
If a faucet only trickles during a cold snap, a pipe may be frozen but not yet broken. The Red Cross advises keeping the faucet open, applying heat to the frozen section with an electric heating pad, hair dryer or towels soaked in hot water, and never using a blowtorch, kerosene or propane heater or other open flame. Call a licensed plumber if you cannot locate or thaw the frozen section.
If a pipe has burst:
- Shut off the main water valve right away.
- Turn off electricity to affected areas if water is near outlets or the panel, and only if it is safe to reach.
- Call a plumber to stop the leak and repair the pipe.
- Document everything with photos and video before cleanup, including the broken pipe.
- Start drying. The policy requires you to protect the property from further damage. Keep receipts for fans, dehumidifiers and water mitigation services.
- Notify your insurer promptly and ask whether it has preferred mitigation vendors.
- Keep damaged materials or photos of them until the adjuster has seen them.

Questions an Adjuster May Ask
Expect the adjuster to ask questions aimed at the reasonable-care rule and the cause of the leak:
- Was anyone living in the house when the pipe froze?
- What was the thermostat set to, and was the furnace working?
- When was the furnace last serviced?
- Where was the pipe, and was it insulated?
- When did you first notice water, and what did you do?
Answer honestly and give records where you have them, such as a furnace service invoice or smart thermostat history. Clear documentation helps show you met the policy’s conditions.
Frequently Asked Questions
Will homeowners insurance pay for a burst pipe?
Usually yes, for sudden water damage to the house and your belongings, minus the deductible, if the home was heated or the water was shut off and drained when required.
Does insurance cover frozen pipes in a vacant house?
Only if you used reasonable care to maintain heat or shut off the water and drain the system. Longer vacancies can trigger additional restrictions.
Does homeowners insurance pay to replace the broken pipe?
Under the ISO HO-3, the policy pays to tear out and replace parts of the building to reach the pipe, but generally not for the pipe or appliance itself.
What temperature should I keep my house to avoid frozen pipes?
The American Red Cross recommends setting the thermostat no lower than 55 degrees Fahrenheit when you are away during cold weather.
Does renters insurance cover frozen pipe damage?
Renters insurance covers your belongings and additional living expenses. The building and pipes are generally the landlord’s responsibility.
The Bottom Line
Frozen pipe damage is generally covered when it is sudden and the home was kept heated or properly drained. Keep the thermostat at a safe temperature, protect exposed pipes, learn where the main shutoff is and act quickly if a pipe bursts, both to limit the damage and to protect your claim.
