One cut line can cost more than the job
Hitting a gas, water or fiber line is the claim excavation contractors worry about most, and some liability policies exclude underground damage unless it's added back. Collapse and subsidence are other common exclusions.
I place earthwork contractors with carriers that write the class and check those exclusions first, then insure the equipment, often the largest asset in the business.
- General liabilityIncluding underground utility damage, collapse and subsidence.
- Contractors' equipmentExcavators, loaders, dozers and trailers.

What underwriters will ask
Having these ready means I can go to market on the first call. The quote form asks for the same things, and anything you don’t know yet can wait.
- Work: excavation, grading, trenching, paving or demolition, with rough percentages.
- Depth: the deepest you dig and whether you do shoring.
- Equipment: a list of machines with values, owned and rented.
- License: your CSLB license and classifications.
- Payroll and revenue: employees, subcontractors and gross receipts.
- History: current policies and loss runs.
Excavation contractor insurance, answered
Does my policy cover hitting an underground line?
Only if it includes underground damage, sometimes called the U in XCU. Some contractor policies exclude it, so it's the first thing I check.
What is XCU?
Explosion, collapse and underground damage. Excavation work needs all three covered.
Is rented equipment covered?
It can be, under contractors' equipment with rented-equipment coverage. Rental agreements usually require it.
Do I have to call before digging?
Yes. California requires contacting 811 before excavating. Carriers expect it, and it helps your defense if a line is hit.
Do you offer excavation contractor insurance outside California?
Yes. Clients across the country send the same quote form. California policies are placed directly; outside California the request is handled together with a partner agency in your state, and the shopping across carriers works the same way. Rules, minimums and markets differ by state — see insurance requirements by state.
Send your work and equipment. I'll shop it.
Work types, an equipment list and your current declarations page are enough to start.
