How much does excavation insurance cost?
For a small excavation operation, general liability typically lands around $800–$3,000 per year — and your real number depends on payroll, limits, state, and claims history. Here’s what actually moves the price.
Typical costs by coverage
⚖️ General Liability
$800–$3,000/yr for a small shop at standard $1M/$2M limits. Revenue, payroll, and your exact operations set the number.
👷 Workers Comp
Rated per $100 of payroll by class code — Excavation codes rate high relative to other trades. State and claims history (your experience mod) move it further.
🚚 Commercial Auto
Commonly $1,500–$3,000/yr per work truck depending on radius, drivers, and equipment like plows or racks.
🧰 Tools & Equipment
Often a few hundred dollars a year, scaled to the gear on your schedule.
Ranges reflect what we typically see for small operations nationally — they’re a starting point, not a quote. Your state, payroll, limits, and history decide the real premium.
What drives your price
- Depth of work — trenching and shoring exposure
- Utility strikes (call-before-you-dig discipline shows up in claims history)
- Owned equipment values — machines cost more than the liability sometimes
- Hauling: dump trucks push commercial auto costs
How to pay less (legitimately)
- Document 811 locate tickets — utility-strike frequency is THE underwriting question
- Inland marine with agreed values on big iron avoids depreciation fights
- Higher deductibles on equipment make sense if you can absorb small hits

How these ranges were developed
The figures above are directional planning ranges for small operations (roughly 1–5 workers) at standard $1M/$2M liability limits, drawn from published small-business premium benchmarks and our own multi-state placement experience as an independent agency. They are not carrier rate filings, not averages of bound policies, and not a quote — your premium is set by the carrier from your payroll, state, class codes, limits, and loss history, and can fall outside these ranges in either direction.

Cost questions we hear
What happens if I hit a gas or fiber line?
Utility strikes are the signature excavation claim — GL responds to third-party damage, but repeated strikes make you unquotable. Documented locate tickets before every dig are your best premium control.
Is my excavator covered under GL?
No — GL covers damage you cause to others. Your machines need inland marine (contractors equipment) coverage, ideally at agreed values.
