Insurance companies don't insure against mold. They insure against the events that cause mold. That distinction decides whether your $8,000 remediation gets paid for or denied. Here's how Minnesota policies handle mold in 2026 and the steps that protect your claim.
The covered-peril rule
Standard HO-3 policies (the common Minnesota homeowner policy) cover mold only when it's the direct result of a sudden and accidental covered peril. The covered peril is the trigger; the mold is the consequence.
Usually covered (event was sudden, accidental, covered)
- Burst pipe, supply line, or water heater rupture
- Overflowing washing machine or dishwasher
- Wind-driven rain through roof damage from a covered storm
- Accidental discharge from a sprinkler system
- Mold from firefighting water after a covered fire
Almost never covered
- Slow leaks (under sinks, behind walls, around toilets) discovered after the fact
- Long-term basement seepage or foundation cracks
- High humidity, poor ventilation, condensation
- Ice dams (some policies cover the water damage but not mold from it)
- Flooding from outside (NFIP flood insurance is separate, and itself rarely covers mold)
- Maintenance issues: missing caulk, broken bath fan, unrepaired roof
The Minnesota cap reality
Most Minnesota HO-3 policies cap mold at $1,000 to $10,000 even when it's covered. A real remediation often runs $3,000 to $30,000 for a finished basement. Read your declarations page (look for "Fungi or Microbe Limited Liability") to see your actual cap.
A mold endorsement raises that cap, usually to $10,000 or $25,000 for $50 to $150 per year. If you have a finished basement, an older home, or anyone in the household with asthma or allergies, the endorsement pays for itself the first time you need it.
How to file a mold claim without losing it
1. Stop the water source first
Shut off the supply, tarp the roof, do whatever it takes. Insurers will deny claims for damage that worsened because you didn't take reasonable steps after discovery.
2. Document everything before you touch it
Photos and video of the source (the burst pipe, the storm damage), the affected area, and the mold itself. Date-stamped, from multiple angles. This is the evidence that the mold came from a covered event.
3. Call your insurer within 24 to 72 hours
Most policies require prompt notice. Get the claim number in writing. Ask whether they want their own adjuster or independent inspection first.
4. Get a written estimate from an IICRC-certified remediator
Insurers take certified contractors more seriously than handyman estimates. The estimate should itemize containment, removal, drying, disposal, and post-remediation verification. Include the moisture source repair separately, that's a different claim line.
5. Don't sign assignments of benefits (AOB)
Some restoration companies push you to sign your insurance rights over to them. In Minnesota this is legal, but it has cost homeowners control of their own claims. Hire your remediator and let them bill you; you pay the insurer's check.
What to do when the claim gets denied
Most mold denials cite long-term leak or lack of maintenance. If you believe the damage was sudden:
- Request the denial reasoning in writing with the specific policy clause cited
- Get an independent moisture inspection report showing the timeline of damage
- File an appeal with the insurer's claims department
- If still denied and the amount justifies it, file a complaint with the Minnesota Department of Commerce or hire a public adjuster
Should you even file?
| Situation | File? |
|---|---|
| Damage clearly under deductible | No, pay out of pocket |
| Damage close to deductible, covered peril | Usually no, premium hit isn't worth it |
| Damage 2x+ deductible, clearly covered peril | Yes, file and document carefully |
| Slow leak, no obvious sudden event | Probably not, expect denial |
| Major flood or burst pipe event | Yes, immediately |
