Frozen Pipes & Ice Dams: What Illinois Home Insurance Pays

Quick answer: A standard Illinois HO-3 policy covers the sudden water damage from a burst pipe or an ice dam, after your deductible. It generally does not pay to repair the pipe itself, remove the ice, or fix damage that seeped in slowly. The exclusion that catches travelers is "failure to maintain heat": if the house is unattended, keep the heat on or shut off and drain the water. Sewer, drain or sump backup needs a separate endorsement, and melting snow coming in from the ground is flood, which needs its own policy.

Every January the same two calls come in: a basement with an inch of water from a pipe that split overnight, and a brown stain spreading across a ceiling under a roofline packed with ice. Is it covered? Mostly yes, with important edges. Here is what an Illinois policy pays, where the exclusions sit, when to absorb a small loss, and what to do before the first hard freeze, with sidebars for Minnesota and Texas.

Does Illinois Home Insurance Cover a Burst Pipe?

Yes, in the standard form. The HO-3 policy most Illinois homeowners carry lists "freezing of a plumbing, heating, air conditioning or automatic fire protective sprinkler system," "accidental discharge or overflow of water or steam from within a plumbing" system, and "weight of ice, snow or sleet" as covered perils, according to the Insurance Information Institute. The plumber's bill to repair the frozen pipe usually is not; carriers treat it as maintenance, although many policies pay to tear out and replace the part of the building opened to reach the leak. Ask your agent how your form handles it.

It is a frequent claim. Across 2019–2023, water damage and freezing produced 1.50 claims per 100 insured homes per year, averaging $15,400, per ISO data published by III, roughly one in 60 insured homes a year. Freeze claims run larger. State Farm reported in January 2026 that from 2024 through June 2025 its customers filed more than 20,000 freeze-related claims totaling over $628 million, with an average payment above $30,000. The five states with the highest total paid were Illinois, Oregon, Washington, Texas and Tennessee, with Illinois listed first.

What Does the "Failure to Maintain Heat" Exclusion Actually Say?

This clause turns a covered loss into a denied one. The ISO HO-3 form excludes freezing damage, then restores coverage if you were careful. As reproduced in FC&S's analysis of the current form, the exclusion "does not apply if you have used reasonable care to: (a) Maintain heat in the building; or (b) Shut off the water supply and drain all systems and appliances of water."

It is either/or. Keep the heat on, or shut off and drain the water.
"Reasonable care" is not a thermostat number. The Insurance Institute for Business and Home Safety and State Farm both say at least 55°F; the Insurance Information Institute recommends 65°F because "the temperature inside the walls where the pipes are located is substantially colder than the walls themselves."
Some carriers go further, limiting the exclusion to vacant homes or adding specific requirements by endorsement. Your policy form controls.

Staying inside the coverage when you travel

Thermostat no lower than 60–65°F, with cabinet doors open under sinks on exterior walls, a step both IBHS and State Farm recommend.
For a long absence, III suggests having the water system drained by a professional and asking a neighbor to check in.
Consider a leak sensor with automatic shutoff; III calls "a water leak monitoring and shut-off system" a worthwhile upgrade, and some carriers credit for one. Photograph the thermostat before you leave.

Are Ice Dams Covered by Homeowners Insurance?

An ice dam forms when attic heat melts snow on the upper roof; the meltwater refreezes at the cold eaves and builds a ridge that forces the next melt under the shingles. III lists "damage resulting from ice dams on your roof" among losses covered by standard homeowners and renters policies: the sudden interior damage to ceilings, insulation, drywall, flooring and contents, after the deductible.

Usually not covered: removing the ice itself, which carriers treat as maintenance like cleaning gutters, and gradual seepage. If the stain has grown for three winters, the insurer will often call the loss preventable. III is blunt: "Your insurance policy will not cover damage due to lack of maintenance, mold or infestation from termites or other pests." The roof is a "depends": shingles lifted by ice are often covered, shingles that failed from age are not, and an older roof may be settled at actual cash value rather than replacement cost.

How Do I Prevent Ice Dams? Roof and Attic Ventilation

An ice dam is a heat-loss problem, so the fix is in the attic. IBHS's Winter Ready guidance says to "ensure you have adequate attic insulation with proper ventilation" and to "insulate attic access doors and seal attic penetrations." The Minnesota Department of Commerce adds that warm air leaking from the house causes most ice dams, so sealing attic leaks with caulk or spray foam beats heat cables, and warns against chipping or chemically melting an existing dam. IBHS says to hire a contractor rather than climb a snow-covered roof.

Is a Frozen Pipe the Same as Water Backup?

No, and the difference decides whether a basement claim is paid. A burst pipe is water escaping from your own plumbing, a listed peril. Water backup is water entering through a sewer, drain or sump pump that fails; III states that "sewer backups are not covered under a typical homeowners insurance policy, nor are they covered by flood insurance," so you need a water backup endorsement. A frozen sump discharge line that sends water back over the pit rim is backup, not a burst pipe. Melting snow coming through the foundation is a third category, flood; the Insurance Information Institute notes that melt seeping in from the ground up falls under flood insurance.

Common Winter Losses: Covered, Not Covered, or Depends?

Winter loss	Standard HO-3	Notes
Water damage from a pipe that froze and burst	Typically covered	After deductible; denied if you did not maintain heat or drain the system while away
Repairing the frozen pipe itself	Typically not covered	Maintenance; tear-out to reach the leak is often covered
Interior water damage from an ice dam	Typically covered	Sudden damage to ceilings, walls, insulation, contents
Ice dam removal, roof raking	Typically not covered	Maintenance, not a loss
Slow seepage over several seasons, resulting mold	Typically not covered	Gradual damage or lack of maintenance; mold limits are often small
Roof damage from weight of ice and snow	Typically covered	Listed peril; older roofs may settle at actual cash value
Sewer, drain or sump pump backup	Depends	Excluded unless you carry a water backup endorsement
Melting snow entering from the ground	Not covered	Flood; requires a separate flood policy
Frozen pipe in a vacant or unheated home	Depends	Covered only with reasonable care to maintain heat or shut off and drain
Hotel costs while the home is unlivable	Typically covered	Loss of use, when the underlying loss is covered

Every row depends on your actual form and endorsements. Use the table to know what to ask, then ask your agent.

How Does the Deductible Work on a Winter Claim?

Your deductible comes off the covered amount first. The all-perils deductible applies to a freeze or ice dam claim; the separate percentage wind/hail deductible many carriers now require does not. If you raised it to $2,500 or $5,000 to offset rate increases, that is the number to weigh before filing. For scale, the NAIC Homeowners Insurance Report puts the average Illinois HO-3 premium at $1,480 for 2023, the latest year published; see our Illinois home insurance page. One $15,000 water claim is roughly ten years of premium.

How Does a Frozen-Pipe Claim Actually Get Paid?

IBHS's after-event guidance: shut off the water supply, call a plumber, and "create a list and take photos or videos to document any property losses." The Illinois Department of Insurance adds: contact your producer or company as soon as possible, make temporary repairs promptly, keep all bills and receipts, and "get prior agreement from your insurance adjuster before you contract for repairs."

From there the claim follows our step-by-step claim guide. Two things surprise people. If your home and contents are insured at replacement cost, the first check is usually the depreciated actual cash value, with the holdback released once repairs are done; see replacement cost vs. actual cash value. And if the house is unlivable, loss of use coverage pays the hotel; III advises saving receipts, including "additional living expenses if you must leave your home until repairs are completed."

Should I File a Small Winter Claim or Absorb It?

Do the arithmetic first. If a $1,000 deductible leaves $900 of covered loss, paying it yourself is usually better: a paid water claim typically stays on your record for several years and can cost a claim-free discount or weigh on a renewal. File when the loss clearly exceeds the deductible, reached more than one room, or traveled somewhere you cannot see. Water damage grows and mold is often excluded, so waiting reliably costs more. If unsure, call your agent; a conversation with your agent is not a claim.

What If a Winter Claim Leads to a Nonrenewal?

It happens, especially after a second water claim. According to the Illinois Department of Insurance, a nonrenewal notice must "clearly articulate the specific reason(s) for nonrenewal," arrive at least 30 days ahead if the policy has been in force less than five years and at least 60 days ahead for almost any reason after five years, and explain your right to appeal to the Director of Insurance and possible eligibility for the Illinois FAIR Plan. Mid-term cancellation is narrower: after a new policy's first 60 days, the Department says a company may cancel only for nonpayment, misrepresentation or fraud, or an increase in the risk originally accepted.

This is where an independent agent earns the relationship. A captive agent can offer one company's answer; we compare 22+ carriers, which differ widely on how they treat one water claim.

Minnesota Sidebar: Ice Dams Are the Main Event

In the Twin Cities the frozen-pipe rules apply unchanged, but ice dams are the bigger winter claim and attic air sealing is the priority project. The Minnesota Department of Commerce warned in a 2019 bulletin that "you may not be covered if you left your house unoccupied without heat or your damage was caused by a slow leak over a longer period of time." NAIC's 2023 data put the average Minnesota HO-3 premium at $1,988; see our Minnesota home insurance page and Minneapolis home insurance guide.

Texas Sidebar: The February 2021 Freeze Changed the Math

The Texas Department of Insurance's homeowners market overview shows water/freeze paid losses of about $838 million in 2020, roughly $4.75 billion in 2021, and about $722 million in 2025. TDI's final data compilation on the February 2021 event counted 511,473 claims across all lines, about $11.5 billion in expected insured losses, 85% of claims on residential property, and an average residential incurred loss of about $17,800; III ranks it the costliest U.S. winter event since 1950. In Texas a power outage, not a thermostat, is the usual reason heat fails, so knowing the main shutoff is the most useful preparation. TDI's preliminary average annual homeowners premium for 2025 is $3,489; see our Texas home insurance page.

Pre-Winter Checklist for Illinois Homeowners

Find and test the main water shutoff.
Disconnect hoses and drain outdoor faucets. IBHS notes homes built before 2010 typically lack frost-proof faucets.
Insulate pipes in attics, crawl spaces and exterior walls. State Farm notes a small crack can release over 250 gallons a day.
Check attic insulation and ventilation, seal hatches and penetrations, and clean gutters.
Service the furnace before the first cold snap, and set travel rules: 60–65°F, cabinet doors open, a neighbor checking, or the water shut off and drained.
Read your declarations page for your deductible, water backup, and whether contents are at replacement cost; see our declarations page guide.

The Bottom Line

A standard Illinois policy pays for the sudden mess a frozen pipe or ice dam makes, not for the pipe, the ice, or years of slow seepage, and not at all if the house was left cold without reasonable care. Know your deductible, know your shutoff, keep the heat on. That is the conversation we have every fall with clients in St. Charles, across Kane County, and throughout Illinois, alongside the hail and wind risks that dominate the rest of the year.

Frequently Asked Questions

Does homeowners insurance cover a frozen pipe that bursts?

Usually yes for the water damage, usually no for the pipe. A standard HO-3 lists freezing of a plumbing, heating, air conditioning or sprinkler system as a covered peril, so the sudden water damage to floors, drywall, cabinets and belongings is typically covered after your deductible. The plumber's bill to repair the frozen section of pipe is generally treated as maintenance and not paid, although many policies do pay to tear out and replace the part of the building that has to be opened to reach the leak. Coverage can be denied if the insurer finds you did not use reasonable care to maintain heat or shut off and drain the water while the home was unattended.

What temperature do I have to keep my house at while traveling in winter?

The standard HO-3 form does not name a number; it requires reasonable care to maintain heat in the building or to shut off the water supply and drain the systems. Guidance differs on what reasonable means: the Insurance Institute for Business and Home Safety and State Farm both say at least 55°F, while the Insurance Information Institute recommends a minimum of 65°F because the space inside exterior walls where pipes run is colder than the room. Setting the thermostat no lower than 60–65°F, leaving cabinet doors open, and having someone check the house is the conservative approach. Some carriers add their own specific requirements by endorsement, so read your policy or ask your agent before a long trip.

Does home insurance pay to remove an ice dam?

Typically not. Removing the ice itself is treated as maintenance, the same as clearing gutters or raking snow off the roof. What a standard policy generally does cover is the sudden interior water damage an ice dam causes, such as stained ceilings, wet insulation and damaged drywall, after your deductible. Damage that built up over several winters from a known leak, and mold that followed it, is often excluded as gradual damage or lack of maintenance. If you are unsure which category your loss falls into, ask your agent before you file.

Is a frozen pipe claim the same as water backup coverage?

No. A frozen pipe that bursts is water escaping from your own plumbing, which is a listed peril on a standard HO-3. Water backup is water coming into the home through a sewer, drain or sump pump that fails, which standard policies exclude unless you buy a water backup endorsement. Both can happen in the same winter: a basement can flood from a burst pipe one week and from a frozen sump discharge line the next, and only one of those is covered without the endorsement. Melting snow seeping in from the ground is a third category, flood, which needs a separate flood policy.

Should I file a claim for a small frozen pipe loss?

Run the numbers first. Subtract your deductible from the repair estimate; if the remainder is small, paying out of pocket usually makes more sense, because a paid water claim typically stays on your claims record for several years and can affect your premium or your renewal. If the damage is large, involves multiple rooms, or you cannot yet see how far the water traveled inside walls or under flooring, file promptly. Water damage grows and mold is often excluded, so delay is the most expensive option. When in doubt, call your agent and describe the loss before deciding; a conversation with your agent is not a claim.
