What should a California contractor prepare for a business insurance review?

Prepare the business name, license or trade information, employee and payroll details, operations, vehicles or equipment when relevant, contracts, prior coverage, and claims history. A licensed team member can then review the request subject to carrier eligibility, policy terms, and underwriting.

How are business insurance limits or terms selected for a contractor?

Limits and terms are not universal. They can be influenced by the contractor's actual work, contracts, employee duties, vehicle use, project requirements, prior loss history, carrier guidelines, and applicable California requirements. The appropriate structure must be reviewed for the individual operation.

The Water Damage Problem

Water claims are the most expensive GL claims a contractor faces. A single pipe failure in a commercial building can cause $50K–$500K+ in damage — and the damage often doesn't show up until weeks after the job is done. Completed Operations coverage on your GL is non-negotiable for plumbers.
