Ask a room of contractors what their General Liability policy is for, and a lot of them will tell you it covers their mistakes on the job. It’s an easy assumption — you carry it because everyone requires it, so it must be the thing that bails you out when work goes wrong. But GL was never built to be a warranty on your workmanship, and the gap between what contractors think it does and what it actually does is where the expensive surprises live. Here’s the distinction that matters.
What General Liability is actually built to do
At its core, a General Liability policy responds to third-party bodily injury and property damage that arises out of your operations — the kinds of accidents that make someone else worse off. A visitor trips over your extension cord and breaks a wrist. Your crew knocks a ladder into a client’s storefront window. A tool drops and damages a finished floor that wasn’t part of your scope. Those are the classic GL claims: harm to someone else’s body or someone else’s property, caused by an accident (an “occurrence”) tied to your work.
That “someone else” framing is the key to everything that follows. GL is liability coverage — it exists to protect you when you’re legally responsible for harm to a third party. It was not designed to guarantee the quality of the product you sell, which is your own construction work.
The “your work” exclusion, in plain English
This is where most of the confusion lives. Standard GL policies generally include what’s known as the “your work” exclusion (and a related “your product” exclusion). In plain terms: GL typically will not pay to rip out and redo your own defective work.
If you install a roof and it leaks because of how it was installed, the cost to tear off and re-lay that roof is generally treated as your business risk — the price of doing the job right — not something GL was meant to fund. The logic is straightforward once you see it: if GL paid to fix every piece of faulty workmanship, it would be a performance guarantee, and premiums would look nothing like they do. Quality control, your contract, and warranties are the tools built for workmanship. GL is built for liability to others.
The part contractors miss: resulting damage is a different question
Here’s the nuance that changes the picture, and why you shouldn’t write GL off after reading the paragraph above. The exclusion is generally aimed at the cost of fixing your own work — but damage that your faulty work causes to other property, or injury it causes to a person, is a separate question that may be treated very differently.
Take the leaking roof again. Redoing the roof itself is one thing. But if the water intrusion ruins the drywall, insulation, and flooring below the roof — property that wasn’t your work — that resulting damage is a different category, and whether it’s covered depends heavily on the specific policy language, endorsements, and facts of the claim. Same idea if a defective install leads to a fire or an injury. The faulty work and the consequences of the faulty work are not automatically the same coverage conversation.
This is exactly why “am I covered?” almost never has a clean yes-or-no answer from a blog post. It turns on your actual policy, its exclusions and endorsements, how the work was performed, and how the loss unfolded — which is a conversation to have with your broker on your specific policy, not a rule of thumb.
Why subcontracted work can change the analysis
One more wrinkle worth knowing, because it connects to something you already deal with every day: whether work was done by your employees or by a subcontractor can affect how the “your work” exclusion applies. Many GL policies treat subcontracted work differently than self-performed work — which is one more reason (on top of additional-insured and certificate requirements) that you want every sub properly insured and documented. The details are policy-specific and get technical fast, so treat this as a flag to raise with your broker rather than something to sort out mid-claim.
Bottom line
General Liability is powerful, but it’s liability coverage, not a workmanship guarantee. As a rule of thumb: the cost to fix your own defective work is generally on you, while injury or damage your work causes to others is where GL is designed to respond — subject entirely to your specific policy. So don’t count on GL to underwrite bad installs; count on your quality control, your contracts, and a coverage program built for the way you actually work. And when a loss is messy enough that “your work” and “resulting damage” blur together — which is most of the time — that’s the moment to get your broker on the phone, not to guess.
