Why Are Some Mold Claims Denied?

Insurance policies typically cover sudden and accidental water damage, but mold that develops over time from a slow leak or high humidity is often considered a maintenance issue. If the mold resulted from a long-term problem you could have addressed, your insurer may deny the claim.

Another frequent reason is the source of the water. Flooding from outside, sewer backups, and groundwater seepage are often excluded or require separate coverage. Mold that follows these events may not be covered under a standard homeowners policy.

• Slow leaks or ongoing humidity issues
• Flood or sewer backup without flood insurance
• Lack of maintenance or timely repairs
• Mold found during a home inspection, not from a covered loss
• Failure to report the damage quickly
• Policy exclusions for mold or fungi

Every policy has specific wording about mold, fungi, and water damage. Some policies exclude mold entirely, while others cover it only when it results from a covered peril like a burst pipe. Reading your policy's exclusions and limitations is essential before you file.

Policies vary, and your insurer decides what is covered. If you are unsure about your coverage, ask your insurance company directly. A local water damage pro can help you understand what to document, but they cannot interpret your policy for you.

If your claim is denied, you can ask your insurer for a written explanation and review the reason. Sometimes a simple error in paperwork or a missing document can be fixed. You may also appeal the decision with additional evidence.

A local water damage pro can provide a detailed assessment of the mold and the source of the water, which you can submit to your insurer. Their documentation often includes moisture readings and visible mold growth, which strengthens your case. However, the final decision on approval rests with your insurer.
