Excavation and grading insurance

Heavy equipment, deep trenches, and underground utility strikes produce catastrophic injury and utility damage claims. A single gas-line strike or trench collapse can be a total-loss event.

What the coverage does for a excavation and grading contractor

General liability responds to two different things for your trade. The first is injury or damage caused while you are working, which for excavation and grading work is striking a buried gas, fiber, or water line, causing an outage or an explosion. 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.

Frequently surplus lines because of the high severity and pollution exposure; some small residential grading work stays with admitted carriers.
