NEW YORK — Insurance carriers are increasingly invoking mold exclusions to deny or limit coverage for mold damage claims, generating a growing number of coverage disputes that restoration contractors and homeowners must navigate carefully to ensure fair claim outcomes.
Most standard homeowner's insurance policies exclude coverage for mold damage that results from long-term moisture problems, neglect, or lack of maintenance. However, mold that results from a covered peril — such as a sudden pipe burst or storm-related water intrusion — is typically covered, at least initially.
The coverage dispute often arises when a carrier argues that the mold resulted from a pre-existing moisture problem rather than the covered water event. Restoration contractors who document the source and timeline of water intrusion carefully — including moisture readings, thermal imaging, and photographs taken at the time of initial assessment — are better positioned to support the homeowner's coverage claim.
Several states have enacted legislation requiring insurance carriers to provide clear written explanations when invoking mold exclusions, and to specify the factual basis for the determination that the mold resulted from an excluded cause. Florida, Texas, and California have the most developed regulatory frameworks for mold coverage disputes.
Homeowners who believe their mold claim has been improperly denied should request a written explanation of the denial, review their policy language carefully, and consider consulting with a public adjuster or insurance coverage attorney. The state insurance commissioner's office can also provide guidance on the claims process and the carrier's obligations under state law.
