Why Mold Is a Big Insurance Problem in the US
Mold is classified by insurers as a secondary peril, meaning it usually results from another problem—like water damage.
According to the Insurance Information Institute (III), mold claims exploded in the early 2000s, forcing insurers to rewrite policies and limit coverage
Today, most insurers consider mold:
Predictable
Preventable
High-cost
High-litigation risk
That’s why coverage is restricted, capped, or excluded in many policies.
When Home Insurance DOES Cover Mold
Home insurance may cover mold only if it results from a covered peril and was sudden and accidental.
✅ Covered Mold Scenarios
Mold damage is usually covered if caused by:
Burst pipes
Sudden plumbing leaks
Water damage from a covered storm
Fire suppression water damage
Appliance malfunctions (washing machine, water heater)
Example:
A pipe bursts inside your wall while you’re away for the weekend. Mold develops before you notice. This is typically covered, including:
Mold remediation
Damaged drywall removal
Repairs (subject to limits)
When Home Insurance Does NOT Cover Mold
Most claims are denied because the mold resulted from ongoing moisture or maintenance failure.
❌ Commonly Excluded Mold Situations
Long-term leaks
Flooding (requires separate flood insurance)
High humidity or poor ventilation
Bathroom mold
Mold discovered months later
Neglect or failure to maintain property
Important:
Flood-related mold is never covered under standard homeowners insurance. You need a separate NFIP flood policy
Mold Coverage Limits (The Fine Print That Matters)
Even when mold is covered, insurers often impose strict caps.
Typical mold sub-limits:
$1,000 – $10,000
Some policies: $0 (full exclusion)
This means:
Your home might suffer $40,000 in mold damage
Insurance pays only $5,000
You pay the rest
Always check the Declarations Page and endorsements.
How to Check If Your Policy Covers Mold
Look for these sections in your policy:
“Fungi, Wet Rot, Dry Rot, and Bacteria”
“Limited Mold Endorsement”
“Water Damage Exclusions”
If you’re unsure, request a written clarification from your insurer.
How to File a Mold Insurance Claim (Step-by-Step)
Filing correctly can make the difference between approval and denial.
Step 1: Stop the Water Source Immediately
Insurance expects mitigation.
Step 2: Document Everything
Photos
Videos
Moisture readings
Contractor reports
Step 3: Notify Insurer ASAP
Delays can void coverage.
Step 4: Get a Professional Mold Inspection
Third-party assessments strengthen claims.
Step 5: Avoid Full Remediation Before Approval
Unless required for health safety.

Health Risks: Why Mold Is Taken Seriously

Options include:
Mold endorsement riders

Premiums increase, but protection may be worth it.
