Plumbing work can involve water damage, customer property, excavation, heat, vehicles, employees, and allegations that appear after a job is complete. A precise application helps the insurer distinguish routine service from higher-risk operations.

Important: This guide provides general educational information, not legal, tax, or insurance advice. Requirements and policy terms vary. Consult a licensed professional about your situation.

Describe the work accurately

Separate residential, commercial, industrial, new-construction, service, drain, sewer, gas-line, fire-suppression, and excavation revenue where applicable. Disclose subcontracted work and any projects outside your normal scope.

Coverage conversations

A plumber may discuss general liability, completed operations, commercial auto, workers’ compensation, tools and equipment, property, pollution, umbrella, and bonds. Contracts and licensing rules can add separate requirements.

  • Water-damage and completed-work exposures
  • Owned vehicles and mobile equipment
  • Employees and subcontractors
  • Tools at jobsites or in transit
  • Contract limits and additional insureds

Review contractor-specific restrictions

Compare exclusions or limitations involving excavation, depth, height, residential work, mold, pollution, hot work, subcontractors, and project size. Confirm that the business name and every described service are reflected correctly before binding.
