Mold Contamination

Mold contamination continues to be a hot topic in the world of insurance. As presented in a previous edition of the Environmental Insider, there has been an increased number of claims related to mold exposure over the last decade.

Outbreaks are commonly discovered during renovations, construction of wood-framed structures, and subsequent to major weather conditions, in which water intrusion damages result in substantial mold growth. This wide-spread exposure to mold has led to an increase in the need for both contracting services and premises pollution insurance. Consequently, this demand increase has prompted underwriters to request more extensive information while evaluating these coverage opportunities, which caused the insurance industry to reevaluate its approach for known and unknown mold coverage.

That said, Great American Environmental Division continues to prosper in its competitive and consistent underwriting approach.

Contractors Pollution

Detecting mold exposure during a construction project–particularly prior to completing the building envelope or during wood-framed construction–represents a financial threat to both the asset and overall project budget. To proactively assist in mold occurrences, contractors and developers are seeking additional coverage options beyond their builder’s risk that will cover the threat of mold, specifically.

Mold coverage has become increasingly important to a variety of contractors today. Regardless of the type of contracting work performed—from an excavation to a roofing, where the need for this coverage may not be obvious—mold coverage is in high demand. Carriers have been fine-tuning their coverage dependent on project specifics such as the type of construction, placement of builder’s risk and construction protocols for water intrusion and mold growth. Coverage restrictions or limitations have become more commonplace and may include coverage for mold on a claims-made basis, a higher self-insured retention, or sub-limits for mold.

Environmental Impairment Liability

Today, mold coverage is essential for any type of occupied building. This includes hotels, hospitals and multi-family residential locations, where a mold claim could trigger multiple coverage sections on a policy including: clean-up, bodily injury/property damage and business interruption.

Property owners or lenders seeking asset or collateral protection from mold in the form of insurance will not experience a dramatic difference in coverage availability. While the number of carriers providing competitive coverage for mold exposures has decreased, there are plenty of carriers, including Great American, that continue to do so. While per-door deductibles are still rare, higher self-insured retentions for mold (dependent on policy term and property use), and restrictions for damage from named-storm events are common-place. Mold coverage is often excluded until after use and occupancy when construction is planned, during capital improvements and/or review of a property condition assessment, or evidence that a known mold condition has occurred.

As claims for mold mature and become more frequent, two things can be expected to remain constant in pollution insurance:

  • The landscape of mold coverage will continue to evolve.
  • Carriers will respond with changes in underwriting or coverage offerings.

Insureds can prepare by being ready to provide information on how they address mold and water intrusion through their practices or procedures when getting ready for a renewal or new coverage request. If an insured does not have such practices or procedures, Great American can provide assistance with developing mold and water intrusion management plans at no cost as part of our value-added services.
