What to Do If Your Subcontractor Doesn’t Have Insurance

Discovering that a subcontractor doesn’t have insurance can happen in two very different places. The first is during contract setup, when the sub can’t produce a certificate and work hasn’t started yet. The second is three weeks into a project when you realize the policy expired and nobody caught the lapse.

Both situations leave the hiring party holding the exposure that the sub’s insurance was supposed to cover, both require immediate action, and the steps each one calls for are different enough that treating them the same usually makes the second one worse.

This article covers both scenarios, along with the legal and financial exposure they create, what insurance subcontractors actually need to carry, how to handle the sub who refuses to get coverage, and how to build a compliance process that catches these problems before they become decisions you have to make under pressure.

What Happens If Your Subcontractor Doesn’t Have Insurance?

If your subcontractor doesn’t have insurance, you might have to absorb the financial and legal exposure their policy was supposed to cover. The NSC puts the average cost of a medically consulted work injury at $48,000 in 2024 and a fatality at $1,540,000, and when the sub has no policy to respond, those costs fall on the hiring party.

Your Legal Exposure as the Hiring Party

Most subcontracts include a hold harmless clause that assigns liability for the sub’s work to the sub. That clause works when the sub has a GL policy to back it. When they don’t, the clause assigns liability to a party with nothing to fund it, and the hiring party absorbs the claim.

The pattern holds across claim types. A sub whose worker injures a third party has the hold harmless clause naming them as responsible. A sub whose completed operations defect surfaces two years after project close faces the same assignment. In both cases, without a policy to respond, the claim reaches the hiring party.

Construction shows the scale of that exposure most clearly. The industry logged 1,034 workplace fatalities in 2024, roughly 1 in 5 of all U.S. workplace deaths that year, leading every individual private industry. The hold harmless failure extends well beyond construction, though. Any organization where subcontractors perform physical work on behalf of a hiring party faces the same consequence when a sub carries lapsed or nonexistent coverage.

The Workers’ Comp Audit Consequence

This is the consequence that catches most hiring parties off guard. It arrives from a scheduled year-end audit and has nothing to do with whether an incident occurred on the job.

At the end of every workers’ comp policy period, the carrier audits subcontractor records and requests a valid certificate for every sub who performed work during that period. The auditor treats any sub who can’t produce a valid certificate as a direct employee and applies payroll classification rates to that sub’s labor charges.

Construction classification rates make the audit charge especially important. The industry represents 27% of all workers’ comp premium volume nationally, the largest share of any single industry in the system, and medical claim severity for construction grew 13% in 2024, more than double the overall system’s growth rate. When the auditor assigns uninsured sub payroll to a construction employer’s policy at those rates, the cost compounds against a baseline that’s already rising faster than any other sector.

The audit clock starts on the first day the uninsured sub worked and runs through the full policy period regardless of the incident record. A project that ran without a single safety problem still produces audit charges if the subs can’t produce valid certificates.

What Happens to Your Own Insurance Program

Some carriers exclude coverage for subcontractor work where the hiring party obtained no certificate. An otherwise insured employer can find their own policy declining to respond to a claim the insurer traces to an uninsured sub’s operations. The exclusion applies because the hiring party accepted uninsured sub risk without documentation, regardless of whether an incident arose.

Uninsured subcontractor incidents build in the hiring party’s own loss history, raise the experience modification rate, and generate underwriting scrutiny that can result in non-renewal for carriers in high-hazard trades. The EMR increase follows into every future premium calculation, prequalification submission, and bonding rate discussion for years.

OSHA’s multi-employer citation policy adds another dimension. It allows inspectors to cite controlling employers, including GCs and project owners, when a subcontractor’s workers are exposed to hazards the controlling employer could have identified or corrected.

Fall protection violations have topped OSHA’s citation list for 14 consecutive years, with 6,307 violations recorded in FY 2024 alone. An uninsured sub incident that triggers an inspection can produce a citation that follows the hiring party’s safety record for years, affecting prequalification approvals, bonding rates, and future contract eligibility.

Are Subcontractors Covered Under the Contractor’s Insurance?

Generally no. A contractor’s GL policy covers the contractor’s own operations and employees, not the independent work of subcontractors. Most GL policies either exclude subcontractor work explicitly or contain conditions that prevent the policy from responding to claims arising from a sub’s independent operations.

When a GC’s Policy Might Extend to a Sub

Some carriers allow GCs to extend their own GL coverage to include a subcontractor’s operations for a specific project, either by adding the sub as an additional insured or by endorsing the policy to cover subcontractor work. When this happens, the sub’s work falls under the GC’s policy for that defined period. A handful of policies also include limited coverage for subcontractor work as a default provision, though the scope of that coverage varies significantly by carrier and policy form.

The practical problem with relying on this is that it transfers risk in the wrong direction. Claims from a sub’s work hitting the GC’s policy drive up the GC’s EMR, consume the GC’s aggregate limits, and can trigger carrier scrutiny or non-renewal. Requiring the sub to carry their own coverage keeps each party’s loss history separate and the GC’s policy reserved for the GC’s own operations.

Workers’ Comp Is a Separate Question

Workers’ comp operates differently from GL, and the rules here catch more GCs off guard. If a sub doesn’t carry workers’ comp and one of their workers is injured, some states treat that worker as the GC’s statutory employee for purposes of the workers’ comp claim.

The GC’s workers’ comp carrier steps in to cover the claim, and the GC absorbs the cost through their own policy and experience modification. Even states that don’t impose statutory employee status still charge the GC’s workers’ comp carrier for uninsured sub labor at audit, as covered earlier in this article.

The statutory employee risk is highest when the GC directs the sub’s work, controls their schedule, or provides tools and equipment. The more control the GC exercises, the more likely a workers’ comp board or court treats the sub’s workers as the GC’s own.

What Insurance Does the General Contractor Need?

Requiring subcontractors to carry insurance is one layer of protection. The GC’s own policy is the other, and several specific coverage elements need to be in place for that layer to actually function when a subcontractor-related claim arrives.

Contractual Liability Coverage

The hold harmless and indemnification agreements that flow upwards from subcontracts also flow upward from your own contracts with project owners and developers. Your GL policy needs contractual liability coverage to honor those obligations. Most standard GL forms include it unless a limiting endorsement like CG 21 39 removes it.

Review your own policy’s endorsement schedule before signing contracts that include broad indemnification language, and confirm the contractual liability provision is intact.

Completed Operations Coverage

Subcontractor work that produces a defect doesn’t always generate a claim while the project is active. Structural defects, water intrusion, and fire suppression failures can come up years after completion.

Your own completed operations coverage needs to extend through the state’s statute of repose for construction defect claims, not just through project handover. If your policy’s completed operations period is shorter than the repose period, you carry uninsured exposure on every project you hand over during that window.

A Subcontractor Endorsement on Your GL Policy

Some GL policies include subcontractor exclusions that limit or eliminate coverage for work performed by subs on your projects. If your policy contains one of these exclusions and a sub’s work produces a claim, your own carrier may decline to respond even though you’re the named defendant. Confirm with your broker whether your policy excludes or limits subcontractor work and what endorsement, if any, restores that coverage.

Umbrella Coverage Sized to Your Projects

Your umbrella or excess policy needs limits that reflect the actual exposure on your largest projects, not a round number that felt adequate at renewal. A $5 million umbrella on a $50 million project with broad indemnification flowing to the owner is a coverage structure worth reviewing with your broker before a claim tests it.

Subcontractor Default Insurance

Subcontractor default insurance, commonly called SDI, is a policy the GC purchases to protect against the cost of a subcontractor failing to complete their scope. Default means the sub can no longer perform, whether through financial failure, abandonment, or an inability to complete the work to specification. When that happens, the GC absorbs the cost of finishing the sub’s scope with a replacement contractor, managing delays, and handling cascading schedule impacts. SDI covers those costs.

SDI addresses a different category of risk from the insurance requirements the GC places on subs. It addresses financial default exposure. Liability for the sub’s work remains a separate question, governed by the sub’s own GL policy and the mechanisms described throughout this article.

What SDI Covers

SDI’s core function is covering the completion cost when a sub can’t finish. Policies typically cover the following:

• The additional cost to hire a replacement sub above the original subcontract value
• Delay damages caused by the schedule disruption
• Extended general conditions costs for the additional time on the project
• The cost to identify and correct defective work at the time of default

SDI doesn’t cover third-party bodily injury or property damage claims arising from the sub’s work. Those claims flow through the sub’s own GL policy, and if that policy is absent, back to the GC through the exposure described earlier in this article.

When SDI Makes Sense

SDI is most commonly used on large commercial projects with multiple major subcontractors whose default would significantly impact schedule and cost. The premium usually runs 0.5% to 1% of the total subcontract volume protected, making it worth evaluating on projects where a single sub’s default could produce losses many times that amount.

It makes less sense for smaller projects or trades where replacement subs are easy to find and the cost of switching is manageable. The value of SDI tracks with the difficulty and cost of replacing the defaulting sub mid-project.

SDI complements subcontractor insurance requirements rather than replacing them. It adds a financial backstop for the scenario where a fully insured sub defaults before completion and the GC needs to fund the difference between the original subcontract value and the cost to finish.

SDI carriers also look closely at a GC’s subcontractor prequalification practices when evaluating coverage. PreQual by Vertikal RMS is accepted and preferred by all SDI carriers, which means GCs who prequalify contractors through PreQual are well positioned when they go to market for SDI coverage.

What to Do When You Discover an Uninsured Sub Before Work Starts

Discovering the problem before work begins gives you full control over how to proceed. The options below are real choices with real tradeoffs, and they’re only available as long as work hasn’t started.

Don’t Let Work Begin

Hold the work until the sub meets the insurance requirements or you’ve settled one of the alternatives below. Every day a sub works without coverage is another day the hiring party carries the exposure, and that clock starts from the first day on the job regardless of whether an incident ever occurs.

Project schedule pressure will push back on any hold, and a sub who can’t produce a certificate creates a real delay problem. Even so, that pressure doesn’t make the underlying exposure manageable. Before resuming any conversation about timelines, document the hold in writing with a specific description of the deficiency and a deadline for resolution. That record matters if a dispute later arises about what coverage was required and when work was authorized to resume.

Your Four Options

When a sub can’t produce the required coverage before work starts, you have four paths forward:

• Require the sub to obtain coverage before starting: This is the cleanest option, and in many cases the fastest one. Most brokers can turn around a GL policy within days, though workers’ comp takes longer in some states and for some trades, so build that timeline into the deadline you give the sub. A sub who can’t afford coverage or can’t obtain it at all signals a financial problem worth knowing before any work begins.
• Add the sub as an additional insured on your own policy: Some carriers allow this, and when they do, the arrangement extends your coverage to the sub’s work, which means claims from the sub’s operations hit your policy and your loss history. That’s a risk transfer in the wrong direction, making this option appropriate only in narrow circumstances, such as a brief scope of work with a trusted sub who is actively obtaining their own coverage and can produce documentation of the timeline.
• Require a surety bond: An EY study commissioned by the Surety and Fidelity Association of America found that bonded projects are five times more likely to finish on time or ahead of schedule than unbonded ones. That performance guarantee is valuable, but it covers the sub’s contractual obligations rather than third-party bodily injury or property damage claims. A bonded sub with no GL policy still leaves the hiring party exposed to those claims, which means bonding works best as a supplement to insurance requirements rather than a replacement for them.
• Proceed with a written indemnification agreement: If the sub has no assets and no insurance, an indemnification agreement is largely theoretical protection. The sub agrees in writing to cover claims arising from their work, but if a claim materializes and the sub can’t pay, the agreement provides a legal basis to pursue them with no practical source of funds behind it. Save this option for low-risk scopes of work, involve legal counsel in drafting it, and document the sub’s capacity to honor the obligation before relying on it.

Setting Requirements by Risk Level

Insurance requirements should grow with the risk level of the work. A subcontractor handling structural demolition warrants higher limits and more specific endorsements than a vendor providing janitorial services, and getting those thresholds right before a project starts is what makes the insurance requirement enforceable when the sub can’t meet it.

The table below gives you a starting point, though contract terms, state regulations, and project owner requirements may call for adjustments above these minimums:

What to Do When You Discover an Uninsured Sub Mid-Project

This is the harder scenario. Work has already started, exposure has already been created, and project momentum works against good decisions. The steps below are different from the pre-work scenario because the problem has a history now, and that history matters.

Stop Work and Document It

Stop the sub’s work immediately and put the hold in writing. The documentation should identify the specific coverage deficiency, the date it was discovered, and the date work was suspended. Every day the sub continues working after you’ve identified the problem extends the period during which the hiring party knowingly carried uninsured exposure, which creates a separate liability problem on top of the original one.

Take pictures of the work completed to date and preserve all daily logs, inspection records, and communications with the sub from the period in question. If a completed operations claim comes up years from now, that documentation establishes what work was done during the uninsured window, under whose supervision, and what quality checks were applied. Without it, the scope and condition of work completed during the lapse period become a disputed fact at exactly the wrong time.

Assess the Coverage Period That Lapsed

Before deciding how to proceed, establish exactly how long the coverage lapse has been in effect. A lapse of three days is a materially different situation from three months of uninsured work, so pin down the timeline before making any decisions. Get four specific things from the sub’s broker:

1. The exact lapse date: Request the cancellation or expiration notice directly from the broker, not from the sub’s own account. The two often don’t match.
2. What the prior policy covered: Review which endorsements were in place and confirm if they actually met the requirements in your subcontract.
3. Whether completed operations coverage extends through the lapse window: Occurrence-form policies can protect work completed before the lapse even after the active policy expires. Confirm this window with the broker before assuming the full lapse period is uninsured.
4. Whether any incidents occurred during the lapse: If the answer is yes, treat those as active claims regardless of whether anyone has filed a formal complaint yet.

Your Options Going Forward

The four options from the pre-work scenario apply here as well, but with an additional complication that changes how you should weigh each one. New coverage obtained today may cover work going forward, but it typically won’t cover work completed during the lapse period. Whether the lapse period work carries coverage depends on:

• How the policy’s written and whether it includes a retroactive date that reaches back through the lapse window
• Whether the sub’s prior policy carries completed operations coverage that extends through the lapse period
• Whether any incidents occurred during the lapse that could produce future claims under either policy
• Whether the new policy’s carrier will accept a risk with a documented lapse in recent history

Get written confirmation from the sub’s broker on each of these before authorizing work to resume. If the sub obtains new coverage and you authorize a restart, document it in writing. That agreement should identify what coverage is now in place, what period it covers, and what work completed during the lapse remains the sub’s uninsured financial responsibility. If a lapse-period claim surfaces later, that document becomes the governing record.

What to Do If Your Subcontractor Refuses to Get Insurance

A sub who can’t produce a certificate and a sub who actively refuses to obtain coverage are different problems. The first is usually a logistics issue. The second is a signal about how the sub views contractual obligations, and it warrants a harder response.

Document the Refusal Immediately

Get the refusal in writing. If the sub communicates their position verbally, follow up with an email that summarizes the conversation and asks them to confirm. That documentation is important because it establishes that you knew about the coverage problem and took action rather than ignoring it. It also creates the paper trail you need if you pursue termination or legal action.

Note the specific coverage the sub refused to obtain, the date of the refusal, and what alternatives, if any, you offered. If the sub claims an exemption from a particular requirement, document that claim and verify it with your insurance advisor before accepting it. Sole proprietor exemptions from workers’ comp, for example, are real in many states but don’t eliminate the audit exposure on your own policy.

Your Contractual Right to Terminate

Most subcontracts give the GC the right to terminate for cause when the sub fails to meet insurance requirements. Review the subcontract before taking any action to confirm what the termination provisions say, what notice is required, and whether a cure period applies.

A cure period gives the sub a defined window to fix the deficiency before termination takes effect. If the sub has already refused, a cure period is effectively a final deadline. Send the cure notice in writing, state the exact deficiency, set a hard deadline, and make clear that work stops at termination if the sub doesn’t comply. That process protects you legally and gives the sub one more opportunity to come into compliance before the relationship ends.

When the Sub Is Already Mid-Project

Mid-project refusal is the harder version of this problem. The sub has leverage because replacing them mid-project carries real schedule and cost consequences. A hiring party who keeps an uninsured sub on the job after a documented refusal is no longer managing an oversight. The decision to proceed is now on the record.

Stop work and assess the cost of replacement against the cost of carrying the exposure for the remaining scope. Get your insurance advisor and legal counsel involved before making that call. If you proceed with the sub under any arrangement other than full insurance compliance, document the decision, the reasoning, and whatever risk mitigation you put in place. That documentation won’t eliminate the exposure, but it demonstrates that the decision was deliberate and managed rather than negligent.

Does a Subcontractor Need Insurance?

Yes. The exact coverage required depends on state law, the trade involved, and what each client’s contracts mandate, but subcontractors working in commercial industries who rely only on meeting legal minimums routinely lose work to subs who carry more.

What State Law Requires vs. What Clients Require

Most states require subcontractors with employees to carry workers’ compensation. Some states require general liability for licensed trades like electrical, plumbing, and HVAC. Beyond those minimums, state law is largely silent.

Commercial contracts fill that silence with requirements that go much further. A typical commercial subcontract specifies the following from every sub on the project:

• GL coverage at project-specific limits, often above state minimums
• Completed operations coverage extending through the statute of repose period
• Commercial auto for any business use of vehicles
• Waiver of subrogation endorsement
• Additional insured status for the GC (CG 20 10 and CG 20 37)
• Primary and non-contributory language

Every one of those requirements lives in the contract, not in state licensing statutes, and a sub who meets only the legal minimum will fail compliance checks before they submit the first bid.

What Insurance Does a Subcontractor Need?

The answer depends on the scope of work, but most commercial subcontracts require the following at minimum:

• Commercial general liability
• Workers’ compensation
• Commercial auto
• Professional liability
• Umbrella or excess coverage above the primary GL

High-hazard trades typically require higher GL limits, and project-specific requirements often exceed these minimums. The endorsements that need to accompany each coverage type are covered in the contract requirements section below.

Why Subcontractors Need Insurance Beyond Compliance

Carrying insurance protects the sub’s own financial position, not just their ability to win bids. Construction workers account for 46.2% of all fatal falls across the entire US workforce, despite representing a far smaller share of total employment, and the industry has logged more than 20,000 nonfatal fall injuries annually since 2013. A subcontractor whose worker sustains a serious injury on a job without workers’ comp absorbs that financial exposure personally, with no insurer to respond.

Beyond personal finance exposure, uninsured subs lose bids before they start. Most GCs and project owners maintain approved sub lists that require documented insurance compliance, and a sub who can’t produce a valid certificate with the required endorsements gets excluded from those lists. GCs who do hire uninsured subs often recover their workers’ comp audit charges through payment deductions, meaning the sub ends up absorbing the hiring party’s insurance costs on top of carrying the uninsured risk themselves.

What About Sole Proprietors and Independent Contractors?

Sole proprietors and independent contractors operate under different rules than subs with employees, and those differences create specific traps for hiring parties who assume the same requirements apply across the board.

Workers’ Comp Exemptions and What They Actually Mean

Most states exempt sole proprietors from the requirement to carry workers’ comp for themselves. A sole proprietor working alone with no employees usually falls outside the workers’ comp mandate in their state, and many will claim that exemption as a reason they don’t need to provide a workers’ comp certificate.

That exemption applies to their own obligation to carry coverage. It doesn’t protect you. When a sole proprietor without workers’ comp gets injured on your job and files a claim, many states treat them as your statutory employee for purposes of that claim. Your workers’ comp carrier responds, the cost hits your policy, and the audit charge follows at year end regardless of the state’s exemption.

The practical response is to require workers’ comp from every sub regardless of their sole proprietor status or to obtain a valid exemption certificate from the state confirming the sub qualifies and to document clearly that you hold it. An exemption certificate doesn’t eliminate your audit exposure in every state, but it demonstrates that you conducted due diligence on the sub’s status before allowing them to work.

When Is a Subcontractor Actually an Employee?

Misclassification is the other trap. A sub who looks independent on paper can be treated as your employee by a workers’ comp board, an IRS audit, or a court, depending on how the working relationship actually functions. The more control you exercise over how the work gets done, not just what the outcome is, the stronger the argument that the sub is an employee.

These are the signals that push toward employee classification:

• You supply the sub’s tools and equipment
• You set their hours and work schedule
• You require them to work exclusively for you
• You direct how the work gets done, down to the method and means, rather than simply specifying the end result

When a worker gets reclassified as your employee after a claim, your workers’ comp carrier covers it, your EMR absorbs the cost, and your state labor authority can layer penalties on top of that for the misclassification itself.

Review how your working relationships with solo operators are actually structured, not just how they’re labelled in the contract. If the substance of the relationship looks like employment, a certificate of insurance and a subcontract label won’t change how a claims board sees it.

How to Write Subcontractor Insurance Requirements Into Your Contracts

Vague contract language produces vague compliance. A contract that says “subcontractor shall maintain proper insurance” gives you no enforceable standard to measure against and no legal ground to stand on when a claim comes up and the coverage falls short.

Contracts that actually hold up include the following elements:

• Coverage types and minimum limits stated explicitly: Name each required policy, specify per-occurrence and aggregate limits for GL, and state the required workers’ comp, commercial auto, and umbrella limits separately. A number only functions as a limit if the contract names it as one.
• Endorsements required by name: CG 20 10, CG 20 37, waiver of subrogation, and primary and non-contributory language should all appear in the contract by name. “Appropriate endorsements” is unenforceable language that produces exactly the compliance problems you’re trying to prevent.
• Annual certificate renewal throughout the project duration: A certificate that was valid when you signed the contract means nothing if the policy lapses six months in. Require renewal certificates before each policy period expires and hold work if the renewal doesn’t arrive.
• Coverage active through the completed operations period: The exposure window keeps running well after the project is completed. Require coverage to remain in force through the state’s statute of repose for construction defect claims, which can run as long as ten years.
• Certificate delivery deadlines: Require the certificate before work starts, built into the subcontract as a hard condition, not left to the sub’s initiative.
• Cure periods and remedies for non-compliance: Specify what happens when a sub fails to produce a required certificate or allows coverage to lapse. Stop-work authority, payment holds, and the right to terminate for non-compliance all belong in the contract before any of those situations arise.

What to Look for on a Subcontractor’s Certificate of Insurance

A certificate of insurance confirms that a policy existed when the certificate was issued. It doesn’t confirm that the policy is still active, that it contains the endorsements your contract requires, or that the coverage terms match what you think they are. Knowing what to check on the certificate and what requires additional documentation to verify is how you run a compliance program that actually catches problems.

Here’s what to check on the face of the certificate:

• Named insured: The named insured on the certificate should match the legal entity named in your subcontract exactly. A certificate issued in a trade name instead of the legal entity, or in the name of a parent company rather than the sub performing the work, can produce coverage disputes when a claim arrives.
• Coverage types and limits: Confirm each required coverage type appears on the certificate with limits that meet your contract minimums. GL limits show as per occurrence and aggregate. Check both. A sub who meets the per-occurrence minimum but carries a depleted aggregate from a prior claim on the same policy period has materially less coverage than the certificate suggests.
• Effective and expiration dates: Coverage dates should run continuously through the project duration. A certificate that expires before the project closes needs to be renewed before the expiration date. Also confirm that GL and workers’ comp periods line up. Misaligned policy periods create windows where one coverage is active and the other isn’t.
• Additional insured status: The certificate should show your organization as additional insured for the applicable coverages. Additional insured status on the certificate is a representation, not a guarantee. The actual endorsement on the policy is what creates the legal relationship.
• Workers’ comp coverage: Confirm workers’ comp appears on the certificate for any sub with employees. A sub claiming sole proprietor exempt status should provide a state-issued exemption certificate alongside the COI.

What the Certificate Can’t Confirm

The ACORD 25 form includes a disclaimer stating it does not amend, extend, or alter the coverage afforded by the listed policies. That disclaimer exists because the certificate is a summary, not a policy. These are the things that matter specifically when you’re relying on a sub’s coverage that don’t appear on a COI:

• Whether the sub’s work is actually covered: Some GL policies contain trade-specific exclusions that eliminate coverage for the exact operations the sub performs on your project. Roofing exclusions, height restrictions, and classification limitations are common examples. A certificate showing compliant limits can represent a policy that excludes the sub’s primary scope of work entirely.
• Whether the required endorsements are in place: A certificate can show additional insured status without the underlying policy containing the correct endorsement. CG 20 10 and CG 20 37 are the forms that create additional insured status for ongoing and completed operations. Confirming those endorsements requires the policy’s endorsement schedule.
• Whether limiting endorsements exist: Endorsements that remove contractual liability coverage, like CG 21 39, don’t appear on the certificate. A sub’s policy can show compliant limits while carrying an endorsement that eliminates the contractual liability coverage your hold harmless clause depends on.
• Whether the aggregate limit is intact: GL policies carry an aggregate limit that caps total claims payments across the policy period. A sub who has already had claims against their current policy may have a depleted aggregate that leaves far less coverage available than the certificate shows.
• Whether the policy is still active: A certificate is evidence that coverage existed on the date it was issued. But policies lapse, expire, or can be cancelled after that date, and the certificate itself has no mechanism to reflect those changes once it leaves the broker’s hands.

How to Prevent Working With Uninsured Subcontractors

Both scenarios in this article trace back to the same two points where a compliance process breaks down. The first is insurance verification before work begins. The second is monitoring after work begins.

Verify Insurance Before Work Begins

CertFocus by Vertikal RMS handles COI verification across the full project lifecycle, including before work starts. Adding a subcontractor record to CertFocus before work begins triggers an automatic COI request and validation. A sub who can’t produce valid coverage at this stage doesn’t start work, which means the discovery scenarios described throughout this article never come up.

GCs who also need to evaluate a subcontractor’s financial health, EMR, and safety performance before approval will find that PreQual by Vertikal RMS provides that deeper assessment alongside the insurance verification.

The Associated Builders and Contractors 2025 analysis of more than a billion construction work hours found that the most safety-committed contractors operated 658% safer than the BLS industry average. A sub who can’t document required insurance has usually not built the safety and risk management infrastructure that goes with it. PreQual by Vertikal RMS’s review of balance sheets, cash flow, bonding capacity, and EMR identifies that pattern before the sub reaches the project.

Track Coverage Throughout the Project

CertFocus by Vertikal RMS monitors policy status throughout the project and alerts your compliance team when coverage lapses or expires before renewal. A certificate valid on day one doesn’t guarantee coverage on day ninety, and CertFocus catches lapses before work continues on expired coverage.

Vertikal RMS’s own data shows 7 out of 10 COIs received from vendors are out of compliance in at least one area. That means most compliance problems arise on certificates that looked fine on arrival, but may not be fully compliant. Our Hawk-I AI flags discrepancies automatically, and credentialed insurance professionals review endorsements and policy documentation to confirm the coverage your contracts actually require is in place.

CertFocus by Vertikal RMS also performs quarterly carrier verification to confirm directly with the carrier that the underlying policies remain active. A certificate can represent a policy the carrier cancelled after issuance, and quarterly verification can catch that before a claim does.

Collect Final Certificates at Project Close

Most compliance programs focus on getting certificates before work starts. Fewer address what needs to happen when work ends. Work through the following steps before releasing payment to each subcontractor:

1. Collect a final certificate from every sub: The certificate should confirm completed operations coverage remains in force and extends through the state’s applicable statute of repose period.
2. Confirm you are listed as certificate holder on the policy: Certificate holder status means the insurer must notify you directly if the sub’s policy is cancelled or lapses before the completed operations period ends. Ask the broker to confirm this at closeout and request a certificate reflecting it.
3. Confirm the sub hasn’t initiated a cancellation: A sub who cancels their GL policy the week after a project handover leaves a completed operations window that can run ten years or more with no insurance behind it. Ask the broker directly before closing out the sub’s scope.
4. Document the coverage status of every sub at substantial completion: Construction defect claims can arise years after handover, and the documentation you hold at project close is what establishes the coverage picture at the time the work was handed over.
5. Preserve those records through the statute of repose period: The period runs from the date of substantial completion. In most states, that means keeping records for at least six to twelve years.

CertFocus by Vertikal RMS maintains compliance records throughout the project duration, giving you an organized record of each sub’s coverage status at every stage including closeout. That documentation becomes your reference point when a completed operations claim arises years after the project closes.

Why Most Uninsured Sub Problems Are Preventable

The situations described in this article don’t have to become crises. They become crises when the compliance process that was supposed to prevent them either skipped verification before approval or stopped monitoring after the first certificate arrived.

Requiring a certificate at contract signing is the baseline. What actually protects you is knowing the coverage is still in force three months into a project, that the sub’s completed operations coverage will extend through the statute of repose, and that the endorsements your contracts require actually appear in the underlying policy. Most compliance programs confirm the first of those things. Fewer confirm the others.

CertFocus by Vertikal RMS manages the full compliance lifecycle, requesting and validating COIs before work begins, monitoring policy status throughout the project, and maintaining records through completion and beyond. CertFocus alone covers every insurance compliance objective in this article.

GCs who also need to assess a subcontractor’s financial health and capacity to perform can integrate PreQual by Vertikal RMS with CertFocus for that additional layer of screening. PreQual is an optional integration, not a requirement, for organizations whose prequalification process extends beyond insurance compliance.
