General liability will not pay to rip out and redo your own defective plumbing, and that surprises a lot of contractors the first time a claim lands. The policy is not a warranty on your workmanship. It is third-party coverage — built to pay for the bodily injury and property damage your work does to other people and other property — and it carries specific exclusions that keep it off the cost of fixing the work itself. When a connection you installed fails, the policy draws a line: the damage the leak does to the finished space around it is one thing, and the cost to re-run the defective line is another. This post explains where that line sits and why.
The general liability page owns the full coverage architecture; this post narrows in on one seam within it. In the standard commercial general liability form — the occurrence version known as CG 00 01 — two exclusions in Coverage A do the work. One carves out damage to your own completed work; the other carves out the particular part of property you are operating on or that has to be redone because your work was wrong. Understanding them is the difference between expecting the policy to fund a callback and knowing, before the claim, exactly which part of a plumbing loss it will and will not answer. Editions and exact wording vary by carrier, so read the language actually attached to your policy against the work you do.
Why general liability is not a warranty on your work
The instinct that general liability should pay to fix a failed connection is understandable and wrong. General liability exists to protect a plumbing contractor from liability to others — the harm the work causes out in the world. It is not there to guarantee the quality of the work or to fund the repair when a piece of it does not hold. That distinction is baked into the policy on purpose: if general liability paid to redo defective work, it would function as a performance guarantee, and it is priced and structured to be third-party liability coverage instead.
So the cost of correcting your own workmanship — pulling out the fitting that failed, re-running the line, re-testing the system — is a business cost, not a covered third-party loss. That is not a gap someone forgot to close; it is the design of the coverage. The policy steps in when your work causes damage or injury beyond itself, and it steps back when the only thing that needs fixing is the work you were paid to perform. Keeping that framing straight is what makes the two specific exclusions below read as logical rather than arbitrary.
The “damage to your work” exclusion
The first exclusion is the one most contractors mean when they talk about the your-work carve-out. In the standard form it is the “damage to your work” exclusion, and it removes coverage for property damage to “your work” arising out of it, within the products-completed-operations hazard — that is, after the job is finished and the work is out in service. In plain terms: once you have completed the plumbing and a defect in that work damages the work itself, the policy will not pay to repair or replace it. The failed connection, the line that has to come back out — that is your work, and the exclusion carves it out.
But the exclusion carries an important built-in relief: the subcontractor exception. The exclusion “does not apply if the damaged work or the work out of which the damage arises was performed on your behalf by a subcontractor.” In practice, that can pull otherwise-excluded damage back into coverage when a sub — not your own crew — performed the work in question. For a plumbing business that hires out portions of a job, this exception matters, because it changes whether damaged work is inside or outside the policy depending on who actually performed it. The exception is specific, and its wording varies by carrier, so it is one to confirm against the policy rather than assume.
The “damage to property” exclusion: work in progress
The your-work exclusion sits in the completed-operations window — after the job is done. A separate exclusion handles the work while it is still underway: the “damage to property” exclusion, which carves out two particular pieces relevant to a plumbing contractor.
- The part you are working on. It excludes that particular part of real property you — or a subcontractor on your behalf — are performing operations on, if the property damage arises out of those operations. This is the ongoing-operations piece: while your crew is actively working on a section of the system, damage to that particular part is outside the policy.
- The part that has to be redone. It excludes that particular part of any property that must be restored, repaired, or replaced because “your work” was incorrectly performed on it. This is the carve-out for the piece that has to come back out and be redone because it was done wrong in the first place.
Together with the your-work exclusion, this keeps the policy consistently off the cost of your own work — the part you are operating on, the part that has to be redone, and the completed work that later fails. There is also a sibling exclusion, “damage to your product,” that operates on the same principle for a product you sell rather than work you perform; for most plumbing contractors the your-work and damage-to-property exclusions are the ones that govern, and the product exclusion is worth a mention but rarely the center of the claim.
Where the line sits: the damage your work causes to others
Here is the part that keeps the exclusions from swallowing the coverage. The your-work exclusion removes the cost to fix your own defective work — but the damage that defective work causes to other, third-party property is the classic completed-operations claim general liability is built to answer. When a fitting you installed lets go and floods the finished space below, the policy can respond to the ruined finishes, flooring, and property around the leak, even as it declines to pay to re-run the line that failed. The line sits precisely between the work and the harm the work causes.
That is the seam worth internalizing, because it is where most of the confusion lives. The leak that damages other property after the job is exactly the loss the completed-operations coverage exists for — a point worth reading in full on whether general liability covers water damage after the job, which takes the covered side of this line the way this post takes the excluded side. The two questions are mirror images: this post is about why the policy will not redo your defective work, and that one is about why it will pay for the third-party damage that work causes. Read together, they draw the full boundary. And it is a boundary the standard general liability policy is designed around, not an accident of drafting.
Real-World Scenario: A plumbing contractor installs the supply lines in a finished commercial suite, passes inspection, and moves on. Weeks later a soldered connection fails and water runs down into the space below, ruining the ceiling, the flooring, and a tenant’s stored goods. Two repair bills arrive: one to re-run the failed line, and one to restore the finished space and replace the damaged property. General liability declines the first — that is the plumber’s own defective work, carved out by the your-work exclusion — and can respond to the second, the third-party completed-operations damage the leak caused. Same event, two bills, opposite answers, split exactly along the line the exclusions draw.
The E&O seam: a judgment error is a different line
There is one more distinction that trips people up, and the honest move is to point at it rather than teach it here. The your-work exclusion is about physical workmanship — the connection that leaked, the line installed incorrectly, the tangible thing that failed. It is not about a mistake in judgment. If a plumbing contractor takes on design, specification, or consulting responsibility and a professional error there causes purely financial loss without any physical damage, that is a different line of coverage entirely.
That exposure runs through professional liability, not general liability. General liability answers bodily injury and property damage; a professional judgment error that produces financial harm without physical damage is outside its scope and belongs to professional liability instead. The point here is only to flag the seam so it is not mistaken for the your-work question: a workmanship failure and a design or consulting mistake are two different claims that land on two different policies. Which one a given loss belongs to is worth sorting out early, before assuming general liability is the policy in play.
Read the exclusions against the work you do
The takeaway is clean once the line is clear. General liability is not a warranty on your workmanship — it will not pay to rip out and redo your own defective plumbing, because the your-work and damage-to-property exclusions keep it off the cost of the work itself, whether that work is in progress or completed. What it does answer is the damage that defective work causes to other property — the completed-operations claim this post’s companion on water damage after the job takes up in full. The subcontractor exception can shift the line when a sub did the work, and a design or judgment error sits on a different policy altogether. Editions and exact wording vary by carrier, so the language attached to your policy is what governs. When you are ready, start a quote and we will read the exclusions against the specific work you do, or read the full general liability page to see how the completed-operations coverage on the covered side of this line actually works.
