Plumbing Contractors
Rough-in and finish work carry different exposure. Completed operations is the coverage that follows your crew's work long after they've moved to the next job. Built around how plumbing contractors actually operate.
Running a plumbing contracting business means managing work across multiple phases and multiple job sites at once — often with crews and subs handling different stages of the same project. That creates a different insurance picture than a solo service tech carries, because the exposure compounds: more installs happening in parallel means more completed-operations tail risk sitting out there at any given time, even after a crew has already moved three jobs down the road.
Underground and behind-the-wall work — supply lines, DWV runs, gas lines before the walls close — is where the highest completed-operations exposure lives. A rough-in connection that's slightly off doesn't usually show itself at inspection. It shows up months later as a stain on a ceiling or a soft spot in a floor, by which point drywall, insulation, and flooring have already gone back in around it. Rough-in failures are also the most expensive to fix, since remediation often means tearing out finished work to get back to the pipe.
Fixture sets, trim-out, water heater hookups, and final connections are more visible and get caught faster if something's wrong — but "faster" for a plumber can still mean weeks after the punch list is signed off. Finish-stage completed operations claims tend to be smaller than rough-in claims, but they happen more often simply because there's more of this work per job.
Here's the scenario that defines a plumbing contractor's real exposure: a crew sweats a joint on a repipe in March. The job passes inspection, the GC signs off, everyone moves on. In June, that joint finally lets go behind a finished wall and floods the unit below. The GC and the property owner come looking for whoever installed the pipe — which is you, even though your crew hasn't been on that site in three months. This is exactly what completed operations coverage responds to, and it's why the coverage matters more for a growing plumbing contractor than almost any other line on the policy. Every active project you complete adds to a tail of exposure that doesn't close out when the invoice does.
Most municipalities require certified backflow preventers on commercial buildings, irrigation tie-ins, and any connection where contamination could enter the public water supply — and many require annual re-testing and re-certification for as long as the device is in service. If your crews install or test these devices, that's an ongoing relationship with a piece of equipment you touched once but that keeps generating exposure (and paperwork) every year it's in the ground. Make sure your policy specifically addresses backflow work rather than assuming it's covered under general plumbing operations.
General liability limits often move from the standard $1M/$2M to $2M/$4M once you're regularly working with commercial GCs. Workers compensation becomes required in most states once you have any W-2 employees — some states require it with even one part-timer. Tools and equipment coverage needs to scale with a growing fleet of pipe threaders, jetters, and drain cameras moving between sites. And if you use subcontractors, your policy needs to reflect how much of your revenue they represent.
Contractors working with multiple GCs need to produce certificates quickly and often, sometimes for several active jobs at once. A blanket additional insured endorsement covers any GC or owner you work for without adding them one at a time, and waiver of subrogation language is standard on most commercial contracts. We build both into your policy so certificate requests don't become a bottleneck.
As your revenue, crew count, and new-construction volume grow, so does your completed-operations tail — which means your coverage needs to grow with it, not just your GL limit. We review this with you at renewal so you're never carrying more exposure than your policy actually accounts for.

FAQ
Yes — that's the exact scenario completed operations coverage is built for. It's part of your GL policy and responds to claims that surface after the work is finished, which is where a plumbing contractor's biggest exposure sits.
Standard GL doesn't always address backflow work cleanly. Tell us if your crews install or test backflow preventers and we'll make sure the policy specifically covers it rather than assuming it falls under general operations.
Generally yes. Rough-in failures are hidden behind walls or under slabs, so they're discovered later and cost more to remediate since finished work often has to be torn out to reach the problem. Carriers factor this into how they view your completed-operations exposure.
Many commercial GCs require $2M/$4M rather than the standard $1M/$2M, especially for new construction and multi-unit projects. We'll match your limits to your actual contract requirements.
Work your subs complete under your contract can still come back to you as the contractor of record. Your policy needs to reflect how much of your revenue is subcontracted, and we typically recommend requiring subs to carry their own GL with certificates on file.
