What Insurance Do You Need as a Concrete Subcontractor Working Under a General Contractor?
- 5 days ago

Working as a concrete subcontractor is one of the fastest ways to keep your crew busy without chasing every project yourself. You show up, execute your portion of the job, and move on to the next site. But right before that first pour or finishing pass, the general contractor asks for a certificate of insurance—and suddenly the question becomes real: do concrete subcontractors need their own insurance?
At Wexford Insurance, we hear this every week from contractors who are stepping into subcontract work or trying to meet contract requirements for larger jobs. Nate Jones, CPCU, ARM, CLCS, AU—our founder and Director of Insurance—has spent years both underwriting contractor risk and advising business owners directly. His perspective is straightforward:
“If you’re performing work under your own name, you carry your own risk—regardless of who hired you.”
Understanding insurance for concrete subcontractors isn’t just about checking boxes for a job. It’s about protecting your business, your crew, and your future contracts.
Let’s break it down clearly so you know exactly what you need and why.
Average Cost of Insurance for Concrete Subcontractors
One of the first questions contractors ask is what this coverage is actually going to cost. Like most business insurance, pricing varies based on how your operation is structured—but here are realistic estimated ranges based on what we see across the market.
General Liability Insurance
Solo subcontractors: $800 – $2,500 per year
Small crews: $2,500 – $6,000 annually
Larger subcontractors: $6,000 – $12,000+ annually
General liability insurance is usually required by general contractors. It protects against claims like property damage or injuries tied to your work.

Workers’ Compensation Insurance
One to three employees: $2,000 – $7,500 annually
Growing crews: $7,500 – $25,000 annually
Larger operations: $25,000+ annually
This coverage becomes essential as soon as you have employees. Concrete work involves lifting, cutting, forming, and repetitive motions—all of which increase injury exposure.

Per truck: $1,500 – $4,500 annually
If you’re hauling tools, forms, or materials, personal auto coverage won’t apply. Commercial auto ensures your vehicles are protected while operating for business.
$500 – $3,500+ annually
This protects mobile tools like saws, mixers, screeds, and finishing equipment—whether they’re on-site or in transit.
$1,000 – $5,000+ annually
Used to extend your liability limits, especially for larger projects where general contractors require higher coverage levels.
What Factors Affect the Cost of Concrete Subcontractor Insurance?
Insurance pricing is driven by risk—and not all concrete subcontractors present the same exposure.
In Nate Jones’s experience as a former underwriting manager, these are the biggest factors carriers evaluate:
Type of Concrete Work You Perform
Not all work carries equal risk.
Decorative flatwork: Lower risk
Foundations and structural pours: Higher risk
Work around heavy equipment or shared job sites: Increased exposure
At Wexford Insurance, we’ve seen that subcontractors involved in structural or multi-trade environments tend to have higher premiums because more can go wrong.
Business Size and Payroll
The larger your crew, the more exposure you bring to a jobsite.
Payroll directly impacts workers’ compensation, and more projects increase liability exposure.
Subcontractor Relationships
If you subcontract work yourself, that adds another layer of complexity. You may be responsible if those workers are uninsured or misclassified.
If you're unsure how regulators determine whether someone is truly an independent contractor, the IRS provides clear guidance on worker classification through its independent contractor definition resource at irs.gov. This distinction matters because misclassification can directly impact your insurance costs and audit results.
Claims History
A clean history helps keep premiums stable.
At Wexford Insurance, one of the most common claims we see with concrete subcontractors involves trip-and-fall incidents during curing stages, or property damage caused by finishing errors. Even a single claim can influence your future pricing.
Contract Requirements
General contractors often dictate minimum coverage limits.
These requirements—like $1M/$2M liability or specific endorsements—can drive up costs but are necessary to secure the work.
Why Insurance Matters Even When Working Under a General Contractor
One of the biggest misconceptions in construction is that the general contractor’s policy protects everyone on the job.
That’s simply not true.
The GC’s insurance is designed to protect the general contractor, not your business. If your work causes damage, the claim is often pushed back onto you.
Nate Jones, CPCU, ARM, CLCS, AU, explains it like this:
“General contractors transfer risk downstream. That means if your work creates a problem, their policy will point right back to your insurance—or to you personally if you’re not covered.”
At Wexford Insurance, we’ve seen this firsthand.
Real Example from Wexford
We recently worked with a subcontractor who completed a sidewalk pour as part of a larger commercial project. A few days later, someone tripped due to an uneven section during curing.
The general contractor’s insurance did not respond. The claim went directly to the subcontractor.
Because he had general liability coverage in place, the situation was handled. Without it, the financial impact could have been significant.
Key Insurance Coverages for Concrete Subcontractors
A solid insurance program doesn’t rely on just one policy—it uses multiple layers of protection.
General Liability Insurance
Covers:
Property damage caused by your work
Third-party injuries
Completed operations claims
This is usually the first thing a GC requests before allowing you on-site.

Protects your employees if they are injured on the job.
Concrete work involves heavy lifting, sharp tools, and repetitive motion—all contributing to injury risk.
Covers trucks and vehicles used in your operations.
Whether you’re transporting forms, tools, or materials, this is essential for day-to-day work.
Protects tools and equipment.
On multi-trade job sites, theft and damage risks increase—especially when multiple crews are working in close proximity.
Extends your liability coverage.
This is especially important for larger commercial projects with strict insurance requirements.
How to Lower Your Concrete Subcontractor Insurance Costs
If your quote feels higher than expected, there are ways to reduce your costs while still protecting your business.
Verify subcontractor coverage
Always ensure anyone working under you carries valid insurance.
Follow safety best practices
OSHA provides clear guidelines on hazard prevention and jobsite safety, and following those standards can reduce claim frequency.
Keep clean documentation
Accurate payroll and job records prevent audit surprises.
Match your policy to your work
Misclassified operations can lead to higher premiums or denied claims.
Bundle policies when possible
Combining coverage often results in better pricing.
Maintain a strong claims history
Fewer claims over time lead to better rates.
Work with a specialized agency
Agencies that understand contractors—like concrete subs—can structure policies more effectively.
Frequently Asked Questions
Do concrete subcontractors need insurance if they work part-time?
Yes. Even part-time subcontractors are usually required to carry their own insurance when working under a general contractor. The exposure exists regardless of how often you work.
Can I rely on the general contractor’s insurance?
No. The general contractor’s policy primarily protects their business, not yours. Claims tied to your work are typically your responsibility.
Is general liability insurance enough by itself?
Often, no. Most subcontractors also need workers’ compensation, auto coverage, and equipment protection depending on their operations.
What if I’m a one-person subcontractor?
You may not need workers’ comp in all cases, but general liability insurance is still commonly required to secure contracts.
Why do GCs require additional insured status?
This allows their policy to be protected under yours in certain situations, reducing their exposure if a claim arises from your work.
