[Homeowners insurance](https://riskado.com/insurance-terms/homeowners-insurance/) may cover mold when it grows after a sudden, accidental water loss that the [policy](https://riskado.com/insurance-terms/policy/) covers, such as a burst pipe or an appliance overflow. [Coverage](https://riskado.com/insurance-terms/coverage/) is often limited or excluded when mold comes from a gradual leak, seepage, humidity, poor maintenance, wear and tear, or flood. Even when the water loss is covered, the policy may pay to repair water-damaged property without paying every cost of mold testing or removal. Check your policy's exclusions, [declarations page](https://riskado.com/insurance-terms/declarations-page/), any mold or fungi sublimit, water-backup coverage, flood coverage and [endorsements](https://riskado.com/insurance-terms/rider/). Right now, stop the water, prevent further damage, photograph what you see, keep damaged materials when it's safe and notify your [insurer](https://riskado.com/insurance-terms/insurer/) promptly.

## Start with what caused the moisture

The cause of the water usually decides the mold question. Most homeowners policies cover sudden and accidental water damage, such as a burst pipe, a toilet overflow or a broken washer hose, and mold that develops on an item damaged by that event may be covered too, according to the [Texas Department of Insurance guide to water damage and mold (opens in a new tab)](https://agate.tdi.texas.gov/tips/when-are-water-damage-and-mold-covered-by-insurance.html). Policies usually don't cover gradual leaks or seepage, or the mold they cause, and a homeowners policy doesn't cover mold from flood.

Flood, seepage or leaks, mold, wear and tear, maintenance and neglect are among the causes homeowners policies typically exclude, according to the [California Department of Insurance residential insurance guide (opens in a new tab)](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/03-res/res-ins-guide.cfm). Your policy's exact wording controls, so find the [exclusion](https://riskado.com/insurance-terms/exclusion/) section and read it alongside any mold endorsement.

### Burst pipes, appliance leaks and hidden leaks

A burst pipe or a sudden appliance failure is the clearest case for coverage, because the water loss itself is usually a covered [peril](https://riskado.com/insurance-terms/peril/). A leak hidden inside a wall or under a floor can still qualify under some forms if it was sudden, but reporting rules matter. Some policy forms set a firm deadline for reporting a hidden loss, counted from when you detect it or should have detected it; the table below gives one example. Write down when you first noticed the stain or smell, and report it right away.

### Roof leaks

A roof leak caused by a covered storm can be treated differently from a leak caused by deterioration, wear or an unrepaired defect. Homeowners policies generally cover water damage from rain entering through a hole in the roof when strong winds or another covered event made the hole, according to the [California Department of Insurance residential claims guide (opens in a new tab)](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/03-res/res-prop-claim.cfm). For a mold claim tied to a roof, the insurer will look at what opened the roof, the roof's condition before that, the interior water damage, how long the leak went on, and any mold exclusion or sublimit. Our page on [whether homeowners insurance covers roof replacement](https://riskado.com/does-homeowners-insurance-cover-roof-replacement/) covers the roof itself.

### Sewer backup and flood

Water that backs up through a sewer or drain is usually covered only through a [water backup endorsement](https://riskado.com/insurance-terms/water-backup-coverage/). Flood is generally excluded from homeowners policies and needs separate [flood insurance](https://riskado.com/insurance-terms/flood-insurance/). Mold that follows either event depends on whether you carry that separate coverage and how it treats mold. For more on how water sources are sorted, see [does homeowners insurance cover water damage](https://riskado.com/does-homeowners-insurance-cover-water-damage/).

![A dripping pipe joint under a bathroom sink with a damp, stained cabinet base](https://riskado.com/blog/does-homeowners-insurance-cover-mold/leaking-pipe.jpg)

The cause of the water usually decides the mold question.

## What the policy may pay for

A covered water loss doesn't automatically pay every mold expense. Repairing or replacing water-damaged property is one thing, and mold remediation and testing is another. Some policies pay for reasonable and necessary repair or replacement of covered property physically damaged by mold that follows a covered sudden and accidental water loss, while excluding the cost of remediation, including testing. The endorsement section below shows how one state sets those options.

So, ask about each cost on its own: testing, containment, removal, disposal, decontamination, drywall and insulation replacement, rebuilding, damaged belongings and additional living expenses if you have to move out. The policy, declarations page, endorsement, [deductible](https://riskado.com/insurance-terms/deductible/) and the adjuster's coverage decision determine which of these are paid.

![A section of drywall cut away near the floor of an empty room, exposing wooden studs](https://riskado.com/blog/does-homeowners-insurance-cover-mold/opened-wall.jpg)

Repairing water-damaged property and paying for mold remediation can be treated separately.

## Mold sublimits and endorsements

A mold or fungi endorsement changes how a policy handles mold. Depending on the version, it can add remediation, testing, containment, removal, disposal, decontamination, repair, replacement and some loss-of-use expenses that the base policy limits or excludes.

Which mold endorsements an insurer must offer is set by each state's law and [insurance department (opens in a new tab)](https://content.naic.org/state-insurance-departments). In Texas, for example, insurers selling homeowners policies must offer mold, fungi or other microbe [endorsements](https://riskado.com/insurance-terms/endorsement/) at 25%, 50% or 100% of the dwelling (Coverage A), personal property (Coverage B) and loss-of-use limits, plus a basic option that covers repair or replacement but not remediation or testing, according to the [Texas Department of Insurance (opens in a new tab)](https://www.tdi.texas.gov/orders/mendorse.html). At the 50% option, a $100,000 dwelling limit carries a $50,000 mold limit.

Other states and policies may use different limits or exclusions, and your endorsement choices and limits must appear in your policy documents. Check your declarations page for any mold or fungi sublimit, and ask the insurer or agent which state-approved endorsement applies to you.

## What to do right after you find mold

Taking the right steps early protects your health and your claim. Report water damage right away, find and stop leaks at the source, and dry wet areas with air circulation and dehumidifiers, according to the [California Department of Insurance (opens in a new tab)](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/03-res/res-prop-claim.cfm). Failing to take reasonable steps to secure the property from further damage may affect coverage for the damage that follows.

1.  Stop the water source if it's safe to do so.
2.  Remove standing water and start drying.
3.  Ventilate and run dehumidifiers.
4.  Photograph and video the damage before cleanup, when it's safe.
5.  List damaged property.
6.  Keep damaged materials, when possible, until the insurer has inspected them.
7.  Keep receipts for emergency repairs, drying equipment and temporary fixes.
8.  Notify your insurer or agent promptly.
9.  Ask before making permanent repairs.
10.  Avoid spreading contaminated materials through the house.

The [NAIC's guide to filing a homeowners claim (opens in a new tab)](https://content.naic.org/article/what-you-need-know-when-filing-homeowners-claim) advises notifying your insurer right away and notes that the time allowed to report varies by state. Try to dry water-damaged areas and belongings within 24 to 48 hours when possible, according to the [EPA's mold information (opens in a new tab)](https://www.epa.gov/mold/mold-information-slideshow).

![A dehumidifier and a floor fan running in an empty room with a damp carpet pulled back from the wall](https://riskado.com/blog/does-homeowners-insurance-cover-mold/drying.jpg)

Dry water-damaged areas and belongings within 24 to 48 hours when possible.

## Cleaning it yourself or hiring help

Exposure to damp and moldy spaces may cause no symptoms, or it may cause a stuffy nose, sore throat, coughing, wheezing, burning eyes, skin rash, allergic reactions or asthma flare-ups, according to the [CDC (opens in a new tab)](https://www.cdc.gov/mold-health/about/index.html). People with weakened immune systems or chronic lung disease can face more serious risks.

Areas smaller than about 10 square feet can often be cleaned by the homeowner, according to the [EPA (opens in a new tab)](https://www.epa.gov/mold/mold-information-slideshow). Larger areas, extensive water damage or contaminated water, such as sewage, are reasons to bring in professional help. Fix the leak, dry what you can, clean hard surfaces with detergent and water, and throw out porous materials that can't be dried. Before discarding anything, photograph it and check with your insurer, since the adjuster may want to see it.

Routine mold testing isn't recommended, because results can't tell you whether someone will get sick and there are no set standards for acceptable indoor levels, according to the [CDC (opens in a new tab)](https://www.cdc.gov/mold-health/about/index.html). The priority is removing the mold and fixing the moisture. If your insurer asks for testing as part of a claim, ask whether the policy pays for it before you authorize the work.

![A bucket, a scrub brush and a pair of rubber gloves on a tiled bathroom floor](https://riskado.com/blog/does-homeowners-insurance-cover-mold/cleanup-supplies.jpg)

Small areas can often be cleaned at home, while larger ones call for professional help.

## Could a mold claim affect renewal or your claims history?

It can, though the effect varies by insurer, state and claim type. The claims history of a home might affect its premium, according to the [NAIC consumer guide to home insurance (opens in a new tab)](https://content.naic.org/sites/default/files/publication-hoi-pp-consumer-homeowners.pdf).

Insurers use the C.L.U.E. database, a property claims history report, when underwriting or rating policies. It can hold up to seven years of claims history, including the date and type of loss, the amount paid and the property address, according to the [Connecticut Insurance Department's C.L.U.E. FAQ (opens in a new tab)](https://portal.ct.gov/cid/knowledge-base/articles/clue-faqs). A reported claim may appear even when nothing is paid, while a general coverage question may be treated differently. Ask your insurer how it classifies a call before you describe the damage, and request your own C.L.U.E. report to check it for accuracy, as described in the [Connecticut guide to your claims history (opens in a new tab)](https://portal.ct.gov/cid/consumer-information-center/consumer-resource-library/get-a-clue-to-you-claims-history).

## If the insurer denies or underpays the claim

Start with the insurer's written coverage position, and compare it with your policy, exclusions, declarations page and endorsements. Then send what supports your side: photos, moisture readings, repair invoices, contractor estimates, your inventory and anything that shows the cause of the water. Ask the insurer to reconsider any facts you dispute.

If you agree the loss is covered but disagree on the cost, check for an appraisal clause. Appraisal addresses the amount of the loss, not whether coverage exists, according to the [Connecticut Insurance Department's guidance on disputing a damage estimate (opens in a new tab)](https://portal.ct.gov/cid/resource-library/homeowner-disputing-insurer-damage-estimate). You can also file a complaint with your [state insurance department (opens in a new tab)](https://content.naic.org/state-insurance-departments). Connecticut's [complaint process (opens in a new tab)](https://portal.ct.gov/cid/consumer-resource-library/the-complaint-process), for example, forwards written complaints to the insurer for a response, though the department can't require payment outside the policy contract. Ask the department whether mediation or arbitration is available, and talk with a lawyer about litigation after reviewing the policy, its deadlines and your state's law.

## Disclosing past mold when you sell

Disclosure rules depend on the state. In Texas, a property owner must give the buyer copies of mold remediation certificates issued in the five years before the sale, under [Texas Occupations Code § 1958.154 (opens in a new tab)](https://statutes.capitol.texas.gov/Docs/OC/pdf/OC.1958.pdf). Michigan's [Seller Disclosure Act, MCL 565.957 (opens in a new tab)](https://www.legislature.mi.gov/Laws/MCL?objectName=mcl-565-957), requires sellers to disclose known conditions on a statutory form that points buyers to indoor air quality and possible allergens, including household mold. In any other state, check the statute and required disclosure form where the home is located.

## Frequently asked questions

### Does homeowners insurance cover mold from a slow leak?

Usually not. Policies generally exclude gradual leaks and seepage, and the mold they cause, as the first section explains. Fixing the leak and documenting when you found it still matters if the insurer reviews the timing.

### Does insurance pay for mold removal?

Not necessarily. Some policies pay to repair or replace water-damaged property but exclude remediation and testing unless an endorsement adds them, so check your declarations page for a mold endorsement and its limit.

### Can I clean mold before the adjuster comes?

You should stop the water and start drying right away to prevent more damage. Photograph everything first, keep damaged materials when you can, and ask the insurer before permanent repairs or large-scale removal.

### How long does a claim stay on my C.L.U.E. report?

A C.L.U.E. report can contain up to seven years of property claims history, according to the [Connecticut Insurance Department (opens in a new tab)](https://portal.ct.gov/cid/knowledge-base/articles/clue-faqs). You can request your report and dispute errors.
