Missouri Concrete Contractor Insurance
Concrete work in Missouri carries a risk profile that a generic contractor policy rarely matches: silica dust generated by cutting, grinding, and coring; slabs, driveways, and foundations that can crack, settle, or spall months after the crew leaves the job site; and heavy mixer trucks, pumps, and finishing equipment that need their own coverage lane. Missouri also has no statewide general contractor license, so compliance runs through whichever city you work in, while workers' compensation kicks in at just one employee for construction trades. The Allen Thomas Group has been an independent, family-owned agency licensed in Missouri since 2003, and we build concrete contractor policies around these specifics rather than a one-size-fits-all template.

What Does Concrete Contractor Insurance Cost in Missouri?
Cost depends primarily on crew size, payroll, and equipment on the road, with workers' compensation typically the largest line item once a contractor has employees. The figures below are national benchmark annual premium ranges, not a quote; your actual cost depends on payroll, the equipment you run, and how much of your work involves cutting, grinding, or coring.
| Business Size | General Liability (Annual) | Workers' Comp (Annual) |
|---|---|---|
| Solo / 1-2 employees | $700 – $1,800 | $2,200 – $4,600 |
| 3-9 employees, mixer trucks and pumps | $2,600 – $6,200 | $6,200 – $14,500 |
| 10+ employees, multiple crews and equipment | $6,500+ | $15,000+ |
What a Missouri Concrete Contractor Policy Should Include
- ✓General Liability with Completed Operations, covers third-party bodily injury and property damage, including cracking, settling, or spalling discovered well after a pour is finished
- ✓Workers' Compensation, required under RSMo § 287.030 once a Missouri concrete contractor has even one employee, and family members within the third degree of kinship count toward that total
- ✓Commercial Auto and Inland Marine, mixer trucks, pumps, and towed or portable finishing equipment typically fall outside a standard auto policy and need their own coverage
- ✓Silica Exposure Documentation and Coverage Review, cutting, grinding, and coring concrete triggers OSHA's respirable crystalline silica standard, and your policy should be reviewed against how your crew actually controls dust on site
Does Missouri Require a Concrete Contractor License?
No. Missouri has no statewide general contractor or concrete contractor license. Licensing is handled city by city, and a registration in one city is not recognized in another.
St. Louis, Kansas City, Springfield, and Columbia each run their own separate contractor registration process, so a concrete contractor working across several Missouri municipalities needs to check requirements in every city on the job list, not just the one closest to home.
Is Workers' Compensation Required for Missouri Concrete Contractors?
Yes, and the threshold is lower than most other Missouri industries. Construction trades, including concrete contracting, must carry workers' compensation once they have just one employee.
Under RSMo § 287.030, most Missouri industries are not required to carry workers' compensation until they reach five employees, but construction trades are required to carry it at one employee, and family members within the third degree of kinship count toward that total, which catches many small, family-run concrete crews off guard.
What OSHA Rules Apply to Silica Dust for Missouri Concrete Contractors?
Cutting, grinding, drilling, or coring concrete puts a contractor directly under OSHA's respirable crystalline silica standard for construction, 29 CFR 1926.1153.
The standard sets a permissible exposure limit of 50 micrograms per cubic meter over an 8-hour average and requires specific engineering controls, such as water delivery or dust collection systems, for named tasks including saw cutting, drilling, core boring, and grinding, all common daily operations for a concrete crew.
How Does Missouri's Mechanics Lien Law Affect a Concrete Contractor's Coverage?
Missouri's mechanics lien law gives concrete contractors a 6-month window to file a lien after work stops, but it also creates a paper trail that insurers and clients may reference if a coverage or payment dispute follows a completed pour.
RSMo Chapter 429 sets the 6-month filing window, and RSMo § 429.012 additionally requires a separate Notice of Rights be provided on residential jobs, a step that is easy to miss on smaller driveway or patio work and can affect a contractor's lien rights even when the underlying work was performed correctly.
