Plumbing Contractor Insurance

Plumbing contractors need general liability, workers' comp, commercial auto, and tools coverage — with extra attention to water-damage claims, which are the trade's biggest exposure, and to gas-line work if you do it.

Key exposures for plumbing contractors

• Water damage (the leading plumbing claim)
• Gas lines and medical-gas work
• Sewer, drain, and excavation/trenching
• Mold following water losses
• Service work in occupied buildings

Coverages a plumbing contractor typically needs

General liability with completed operations, workers' comp, commercial auto, and a tools/inland-marine floater. Given water-damage severity, adequate limits and a clean loss history matter.

Workers' comp note

Plumbing carries a moderate workers' comp rate; trenching and confined-space work raise the hazard. See workers' comp in California and how your X-Mod works.

FAQ

What's the biggest insurance risk for plumbers?

Water damage. A single failed connection in an occupied building can cause a large property-damage claim, so coverage and limits should reflect that.

Does plumbing insurance cover gas-line work?

It can, but gas and medical-gas work is underwritten carefully; disclose it so the policy is written correctly.
