The best contractor insurance companies for most trades are The Hartford, Travelers, Zurich, CNA, and Liberty Mutual — carriers that combine broad contractor-specific endorsements, competitive pricing across construction classifications, and proven claims performance. Specialty markets like Markel and AmTrust fill gaps for high-hazard or non-standard risks. Who this is for: General contractors, subcontractors, and specialty trades comparing carriers before buying or renewing a commercial policy.
TL;DR — Key Takeaways
- No single carrier is best for every trade: roofing, electrical, and HVAC face sharply different underwriting appetites and pricing.
- General liability (GL) for contractors is almost always written on an occurrence basis — make sure any policy you compare uses occurrence, not claims-made.
- Workers' compensation premiums are driven by your payroll, state classification codes, and experience modification rate (EMR) — carrier selection matters less than your loss history.
- Independent agencies like Morrow can quote the same risk across 10+ carriers in one submission, surfacing pricing and coverage differences you won't find by going direct.
- The cheapest policy rarely wins on a jobsite. Carrier financial strength (A.M. Best A- or better), certificate turnaround speed, and additional-insured endorsement breadth often matter as much as premium.
What Insurance Do Contractors Actually Need?
Before comparing carriers, you need to know which coverages apply to your trade and contract requirements.
| Coverage | What It Covers | Typical Limit | Who Needs It |
|---|---|---|---|
| Commercial General Liability (GL) | Third-party bodily injury & property damage from your operations | $1M/$2M occurrence/aggregate | All contractors |
| Workers' Compensation | Employee medical bills & lost wages from work injuries | Statutory (varies by state) | Any contractor with W-2 employees (most states) |
| Commercial Auto | Vehicles used for work — owned, hired, non-owned | $1M CSL is common GC requirement | Contractors using vehicles on the job |
| Inland Marine / Tools & Equipment | Theft or damage to owned tools and equipment in transit or on-site | Scheduled or blanket; $10K–$500K+ | All trades with significant tool inventory |
| Builder's Risk | Structure under construction — fire, wind, theft, vandalism | Project value | GCs on new construction or major renovations |
| Professional Liability (E&O) | Design errors, specification mistakes | $1M/$2M | Design-build firms, engineers, architects |
| Umbrella / Excess Liability | Limits above GL, auto, and employer's liability | $1M–$10M common | Any contractor facing large-project contracts |
Coverage note: GL policies for contractors typically cover completed-operations liability (injuries or damage that surface after the work is done) within the aggregate limit. Confirm this is included — some low-cost policies carve it out.
Top Contractor Insurance Companies: Carrier-by-Carrier Breakdown
The Hartford
Best for: Small-to-midsize general contractors and specialty trades seeking a broad BOP (Business Owner's Policy) with contractor-specific enhancements.
The Hartford's contractor GL and BOP products include optional additional-insured blanket endorsements, waiver of subrogation, and primary/non-contributory wording — the three endorsements GCs and property owners most commonly require on certificates. Their ACORD-compliant certificate issuance is fast, which matters when a GC gives you a 24-hour window to produce proof of insurance before you can mobilize.
Typical appetite: Artisan contractors, remodeling, painting, drywall, flooring, landscaping — revenue typically under $5M.
Travelers
Best for: Mid-to-large general contractors and mechanical, electrical, and plumbing (MEP) subcontractors.
Travelers is one of the largest commercial insurers in the U.S. by premium volume (NAIC data) and has deep construction underwriting capacity. Their Wrap+ endorsement suite includes contractual liability, XCU (explosion, collapse, underground) coverage where needed, and robust completed-operations protection. Travelers also offers integrated GL and workers' comp accounts, which simplifies audits and reduces gaps.
Typical appetite: General contractors with $1M–$50M+ revenue, MEP trades, structural steel, concrete.
Zurich North America
Best for: Large general contractors, heavy civil, and infrastructure projects requiring manuscript endorsements or wrap-up (OCIP/CCIP) programs.
Zurich's construction practice is purpose-built for complex projects. They underwrite owner-controlled and contractor-controlled insurance programs (OCIPs and CCIPs), builder's risk on large projects, and wrap-up GL programs for hospitals, stadiums, and infrastructure. For smaller contractors, Zurich's appetite is more limited and pricing is rarely the lowest.
Typical appetite: Annual revenues $10M+, heavy construction, infrastructure, public works.
CNA
Best for: Specialty contractors needing strong professional liability (E&O) alongside GL — especially design-build firms and MEP engineers.
CNA's Construction Wrap endorsement bundles GL, professional liability, and pollution liability in one policy form, which eliminates coverage gaps that arise when these lines are placed with different carriers. CNA is also frequently cited for strong claims handling in construction defect matters.
Typical appetite: Mechanical, electrical, plumbing, design-build, environmental remediation.
Liberty Mutual
Best for: Contractors prioritizing a financially strong carrier for large umbrella towers or excess limits.
Liberty Mutual (A, Excellent per A.M. Best) writes large commercial construction accounts and is commonly used in umbrella and excess liability towers on complex projects. Their primary GL appetite overlaps with Travelers and Hartford, but Liberty's excess capacity is a differentiator for contractors needing $10M+ total limits.
Typical appetite: GCs and specialty contractors needing $5M–$25M+ umbrella/excess, large infrastructure.
Markel
Best for: Higher-hazard trades declined by standard carriers — roofing, demolition, tree removal, blasting.
Markel operates in the excess and surplus (E&S) lines market for construction, meaning they take risks that standard carriers decline. Premiums are higher, and policies may contain more exclusions than standard markets, but for a roofing contractor with prior losses or a demolition subcontractor, Markel may be the only viable admitted or E&S option.
Typical appetite: Roofing, tree surgeons, demolition, blasting, asbestos abatement, contractors with prior losses.
AmTrust Financial
Best for: Small contractors and artisan trades needing affordable workers' compensation, particularly in competitive states.
AmTrust is one of the largest writers of small-business workers' comp in the U.S. Their appetite for artisan contractors — electricians, plumbers, HVAC techs, painters — at payrolls under $500K/year is strong, and their loss control resources help small employers manage EMR over time.
Typical appetite: Artisan trades, 1–10 employees, payroll under $500K.
How Much Does Contractor Insurance Cost? (By Trade)
Premiums vary by trade classification, revenue or payroll basis, state, claims history, and project types. Ranges below reflect annual GL premiums for a small-to-midsize contractor with a clean loss history.
| Trade | GL Annual Premium (Typical Range) | Premium Basis | High-Risk Factor |
|---|---|---|---|
| General Contractor | $3,500 – $9,000 | Revenue (% of gross) | Subcontractor management, completed ops |
| Electrician | $1,800 – $4,500 | Payroll | Wiring errors, fire risk |
| Plumber | $1,800 – $4,000 | Payroll | Water damage, completed ops |
| HVAC Contractor | $2,000 – $5,500 | Payroll | Refrigerant liability, gas lines |
| Roofer | $5,500 – $18,000+ | Payroll | Fall exposure, hail/storm claims |
| Painter (Interior) | $1,500 – $3,500 | Payroll | Relatively low hazard |
| Concrete / Masonry | $3,000 – $8,000 | Payroll | Heavy equipment, structural risk |
| Landscaper | $1,200 – $3,000 | Payroll | Low-to-medium hazard |
| Demolition | $8,000 – $25,000+ | Payroll | Very high hazard, E&S market |
These are illustrative ranges based on industry-typical underwriting and are not a guarantee of pricing. Actual premiums depend on your specific exposures, state, and carrier.
Workers' compensation premiums are calculated separately using state-mandated classification codes, your payroll, and your EMR (experience modification rate). An EMR of 1.0 is the industry average; a 0.85 means your losses are better than average and you receive a 15% credit. An EMR of 1.25 increases your base premium by 25%.
How to Compare Contractor Insurance Carriers in 6 Steps
- Define your coverage requirements first. Pull any GC or owner contracts you work under and list every insurance requirement: minimum GL limits, additional-insured wording, waiver of subrogation, primary/non-contributory language, umbrella minimums.
- Gather your exposure data. Annual revenue (for GL), total payroll by classification (for workers' comp), vehicle count and VINs (for commercial auto), and a schedule of owned equipment with values (for inland marine).
- Check carrier financial strength. Only consider carriers rated A- or better by A.M. Best. Confirm the carrier is admitted in your state (or understand why an E&S carrier is being used).
- Submit to multiple carriers through a single broker. An independent agent can place your risk with 5–15 carriers in one submission. Going direct to one carrier limits your options.
- Compare apples to apples — not just premium. Verify occurrence vs. claims-made, completed-operations inclusion, sublimits on key endorsements, and certificate/COI turnaround capability before choosing.
- Review annually. Your revenue, payroll, and project types change. A policy that fit your business at $800K revenue may be misaligned at $2M — and an audit could expose a large additional premium.
Real-World Example: Electrical Subcontractor in Texas
This is an illustrative example, not a guarantee of coverage or pricing.
Business: A licensed residential and light-commercial electrician in Austin, TX. Three W-2 employees, $650,000 annual payroll, $1.2M annual revenue, no prior GL claims, one minor workers' comp claim two years ago (EMR: 1.05).
Contract requirement from GC: $1M/$2M GL occurrence, $1M employer's liability, $2M umbrella, additional insured (ongoing and completed ops), primary/non-contributory wording, waiver of subrogation.
Illustrative policy structure placed through an independent broker:
| Policy | Carrier | Illustrative Annual Premium |
|---|---|---|
| GL ($1M/$2M, occurrence, blanket AI, P/NC, WOS) | The Hartford | ~$3,200 |
| Workers' Comp (TX statutory; 3 employees, payroll $650K, EMR 1.05) | AmTrust | ~$14,500 |
| Commercial Auto (2 vans, $1M CSL) | Progressive Commercial | ~$3,800 |
| Umbrella ($2M over GL/WC/Auto) | Travelers | ~$1,800 |
| Inland Marine (tools & equipment, $45K blanket) | The Hartford | ~$600 |
| Total annual program | ~$23,900 |
Note: Texas is one of the few states where workers' comp is not legally required for private employers [verify state rules], but most GC contracts require it. Payroll-based workers' comp premiums are subject to year-end audit.
FAQ: Best Contractor Insurance Companies
What is the best insurance company for a general contractor? Travelers and The Hartford are consistently strong choices for general contractors. Travelers offers deeper capacity for larger projects and MEP-heavy operations; The Hartford is typically more competitive for smaller GCs and artisan trades under $5M in revenue. The "best" carrier depends on your project type, revenue, and state.
Is GL for contractors occurrence or claims-made? Contractor GL policies are almost always written on an occurrence basis, meaning coverage applies to incidents that happen during the policy period, regardless of when the claim is filed. This is the correct form for most construction risks. Claims-made GL (more common in professional liability) creates a "tail" problem if you switch carriers without purchasing extended reporting period (ERP) coverage.
Do I need workers' comp if I'm a sole proprietor? In most states, sole proprietors without employees can opt out of workers' compensation coverage for themselves. However, if you hire subcontractors who are not properly classified as independent contractors, you may be required to cover them. Many GC contracts also require subs to carry workers' comp regardless of headcount. Check your state's specific threshold and opt-out rules [verify state].
What does additional insured mean on a contractor policy? An additional insured endorsement extends GL protection to a third party — typically a general contractor or property owner — so they are covered for claims arising from your work. This is different from a certificate holder, who only receives evidence of insurance but no coverage. Standard GC contracts require you to name them as an additional insured for both ongoing operations and completed operations.
How does my EMR affect my workers' comp premium? Your experience modification rate (EMR) compares your actual loss history to the expected losses for your trade in your state, calculated by NCCI (or an independent state rating bureau in non-NCCI states). An EMR below 1.0 lowers your premium; above 1.0 raises it. A single serious injury can push an EMR above 1.0 for three years. Safety programs, prompt incident reporting, and return-to-work protocols are the primary tools for improving your EMR over time.
Why is roofing insurance so expensive? Roofing has among the highest occupational injury rates of any construction trade (Bureau of Labor Statistics data), and the completed-operations exposure — leaks and water intrusion discovered months or years after work is done — is substantial. Many standard carriers exclude roofing entirely or cap policy limits, pushing roofers into the E&S market where premiums are higher.
What is an OCIP, and should I opt in or out? An owner-controlled insurance program (OCIP) is a wrap-up policy purchased by a project owner that covers all contractors and subcontractors on a single large project. If you are enrolled in an OCIP, your own GL and workers' comp do not apply to that project. Before opting in, verify: (1) the OCIP's limits and completed-operations tail, (2) whether your own policy gives you a credit for enrolled payroll/revenue, and (3) how claims would affect your own EMR.
Can one carrier cover all my contractor insurance needs? Often yes — carriers like The Hartford, Travelers, and CNA offer package or BOP-based programs that bundle GL, commercial auto, and inland marine. Workers' comp is sometimes bundled with the same carrier. However, for complex risks or large umbrellas, spreading coverage across two or three carriers (each writing what they do best) usually produces better pricing and broader terms.

3. Contractor-specific expertise.
