In short: Washington's Office of the Insurance Commissioner notes that most homeowners policies don't cover mold, though some offer limited coverage. Mold is most likely to be covered when it results from a sudden, accidental event the policy covers, like a burst pipe, and least likely when it comes from a slow leak, long-term humidity or flooding. Many policies cap mold payouts with a sublimit.
This is general information, not insurance or legal advice. Your policy wording decides your coverage. Read it, and ask your agent or insurer.
When mold is often covered
- A burst or frozen pipe
- A sudden appliance failure, like a water heater or washing machine supply line
- Water from putting out a fire
- A sudden roof leak caused by a covered storm
Even then, coverage is typically tied to the water claim and may be limited by a mold sublimit in the policy.
When mold is usually not covered
- Slow, ongoing leaks under a sink or behind a shower that went unrepaired
- Long-term humidity and condensation, including most attic and crawl space mold in Bothell homes
- Lack of maintenance: clogged gutters, failed caulk, disconnected bath fans
- Flooding from the Sammamish River, North Creek or other surface water. Standard homeowners policies exclude flood; that needs separate flood insurance
- Delay. If a covered leak isn't dealt with promptly, the mold that follows can become a point of dispute
Renters insurance typically doesn't cover mold either, though it may cover some damaged belongings depending on the cause.
How to document a mold claim
Stop the water and protect the property
Policies expect reasonable steps to prevent more damage. Shut off the water and start drying, but don't throw anything out yet.
Photograph and video everything
The source, every wet or moldy area, damaged belongings, and the date. Before cleanup, not after.
Report it promptly
Call your insurer or agent, get a claim number, and ask directly about mold coverage and limits.
Get a written assessment
The cause, moisture readings, affected materials and square footage, and a line-item scope. Adjusters respond to specifics. Our inspections.
Keep every receipt
Emergency drying, plumbing repairs, temporary housing, testing and remediation invoices.
Get clearance in writing
A post-remediation verification report closes the loop. About clearance testing.
If your claim is denied
- Ask for the denial in writing, citing the specific policy language
- Compare that language with the cause shown in your documentation
- Ask your agent whether an endorsement or rider applies

Protecting yourself before the next storm
- Read your policy's mold, water-damage and water-backup sections
- Ask about water backup coverage (for sewer and sump pump backups) and a separate flood policy if you're near the river or creeks
- Fix slow leaks and moisture problems early. Gradual damage is the most common reason mold isn't covered
