Trade coverage

Plumber insurance

Water damage from a failed repair is one of the most common and expensive construction claims, and gas and sewer work adds injury risk. Leaks often surface long after the job is finished.

What the coverage does for a plumber contractor

General liability responds to two different things for your trade. The first is injury or damage caused while you are working, which for plumber work is water damage discovered weeks after a supply line or fitting repair. The second is a claim that surfaces after you have finished, known as completed operations, and it is the half of the policy most often missing from a cheap quote.

Mostly admitted for residential service work; commercial and high-limit plumbing work is sometimes placed in surplus lines.
