What Happened?

A plumbing scope was awarded to a subcontractor, and insurance documentation was collected for the project file. Weeks later, the subcontractor’s policy was cancelled for nonpayment. A subsequent plumbing failure caused extensive water damage, triggering claims and demands from multiple parties connected to the project.

Why It Matters

When a subcontractor causes a major loss but has no active insurance, claims and contractual demands may move upstream. The general contractor can face pressure from the building owner, tenants, restoration companies, attorneys, and other parties while questions arise over contracts, additional insured status, deductibles or self-insured retentions, and the GC’s own coverage.

How JC Family Insurance Helps

We help general contractors evaluate insurance programs around the work they actually perform and the subcontractors they hire. That includes reviewing subcontractor exposure, certificate procedures, additional insured requirements, policy options, and potential coverage gaps before a major loss occurs.

A Certificate of Insurance Is Not a Coverage Guarantee

A certificate of insurance provides evidence of insurance information at a point in time. It does not guarantee that a policy remains active, change the policy terms or automatically create additional insured coverage.

Questions General Contractors Should Ask About Subcontractors

  • Was the Subcontractor’s Policy Active?
    Coverage status on the actual date of loss can become a critical issue. List 1

  • Was the GC an Additional Insured?
    A certificate alone does not necessarily establish additional insured status.

  • What Does the Contract Require?
    Indemnification and insurance provisions may affect how demands develop.

  • Could the GC’s Own Policy Be Involved?
    Response depends on actual policy language, exclusions, endorsements, facts, and applicable contracts.

  • Were Completed Operations Requirements Addressed?

    Some losses arise after a subcontractor has completed its work. Applicable coverage

    depends on policy language, endorsements, contracts, and the facts of the loss.

  • Was Coverage Reverified During the Project?

    making ongoing insurance tracking important.

Common questions answered

Answers to Frequently Asked Questions

What happens if a subcontractor causes damage without insurance?

If a subcontractor causes property damage or bodily injury without active insurance, affected parties may pursue recovery from the subcontractor and potentially other parties involved in the project. The outcome depends on the facts, contracts, insurance policies, and applicable law.

Does a certificate of insurance prove a subcontractor is currently insured?

A certificate of insurance provides evidence of insurance information at a point in time. It does not guarantee that coverage remains active or change the terms of the underlying policy.

What if a subcontractor’s insurance is cancelled after providing a COI?

If coverage is cancelled before a loss occurs, the subcontractor may not have active coverage for that later event. Whether other insurance responds depends on the policies, endorsements, contracts, timing, and facts involved.

Is a general contractor responsible for an uninsured subcontractor?

Not automatically in every situation. However, a general contractor may face claims, contractual demands, defense costs, or other exposure depending on the project relationships, allegations, contracts, and circumstances of the loss.

Should general contractors track subcontractor insurance expiration dates?

Tracking expiration dates can be an important part of subcontractor insurance controls, especially on longer projects or ongoing relationships where coverage may expire or change during the work.

What insurance should a general contractor carry when using subcontractors?

Needs vary by operation, but coverage may include commercial general liability, commercial auto, workers’ compensation where applicable, umbrella or excess liability, builders risk, contractor equipment coverage, and other specialized policies.

Does JC Family Insurance work with general contractors using subcontractors?

Yes. JC Family Insurance helps contractors in Washington, Oregon, and Idaho compare insurance options based on their actual operations, including subcontractor use, project types, payroll, vehicles, equipment, and contract requirements.

Does a COI make a general contractor an additional insured?

Not by itself. Additional insured status generally depends on the underlying policy, applicable endorsement, and potentially written contract requirements.
