The Hidden Risks Most Contractors Don’t Realize They’re Not Covered For

Most contractors assume their insurance policy has them covered. They paid the premium, got the certificate, and moved on to the next job. But a surprising number of claims get denied every year because the coverage gap was right there in the policy language, and nobody caught it in time.

The truth is, hidden risks rarely announce themselves until a job goes sideways. Here are five coverage gaps that catch contractors off guard.

Faulty Workmanship Isn’t Automatically Covered

Standard general liability policies exist to cover third-party bodily injury and property damage caused by accidents. But what many contractors don’t realize is that the work itself, and the cost to fix it, often falls outside that protection. If a client claims your crew installed something incorrectly and demands repair costs, your insurer may point to a “your work” exclusion buried in the policy and deny the claim entirely.

Contractors’ insurance policies vary in how they handle faulty workmanship claims, and the difference between what’s covered and what’s excluded often comes down to a single endorsement. Some policies cover resulting damage to other parts of a structure (water damage from a faulty roof, for instance), but exclude the cost of redoing the defective work itself. Others exclude both. Before you sign a contract on a large project, review your policy language for terms like “your work exclusion” and “products-completed operations.” If those sections aren’t clear, ask your agent directly whether a workmanship claim on a finished job would trigger coverage or hit a wall.

Employee Injuries From Non-Owned Equipment

Workers’ compensation covers your employees on the job site, up to a point. One common blind spot involves injuries that happen on equipment your crew didn’t own or bring to the site. Subcontractors’ tools, rented machinery, or equipment provided by a property owner all create a gray area that standard workers’ comp policies don’t always address cleanly. A crew member gets hurt on a rented scissor lift; the rental company disputes liability; your policy may not respond the way you expect.

The gap gets wider for contractors who use subcontractors regularly. If a sub gets injured and their own coverage lapses, they may look to you for compensation. Without the right endorsements or a blanket additional insured clause, you could be paying out of pocket for an injury involving someone you didn’t technically employ. The fix usually involves verifying certificates of insurance from every sub before work starts, confirming their workers’ comp is active, and keeping those records on file throughout the project; a lapsed sub policy is one of the most common triggers for unexpected contractor liability.

Damage to Property in Your Care

General liability protects against damage you cause to someone else’s property by accident. But there’s a specific exclusion in most standard GL policies called “care, custody, or control.” This exclusion applies when the property that gets damaged was in your possession at the time. A remodeling contractor accidentally breaks a client’s custom window during installation; a plumber damages flooring while accessing a pipe, both may find that the GL policy won’t pay because the property was in their care at the time of the loss.

This is a gap that affects a wide range of trade contractors. The coverage that typically addresses it is called inland marine or contractor’s equipment coverage, and it works differently from standard liability. Some contractors add a care, custody, or control endorsement to their GL policy to patch this hole; others rely on separate inland marine policies. The right answer depends on what kind of work you do, how often you handle client property directly, and the dollar value of what you’re typically working around. Left unaddressed, a single incident involving expensive client property can result in a five-figure out-of-pocket loss that no other policy will touch.

Vehicles Used for Work But Titled Personally

Commercial auto insurance is one of those coverage areas that seems clear until something goes wrong. If you or an employee drives a personally owned truck to a job site, hauls materials, or tows a trailer with tools in it, a personal auto policy almost certainly won’t cover an accident that happens during that trip. Personal auto carriers routinely deny claims when the vehicle was in commercial use at the time of the loss. That denial can leave you exposed to a lawsuit, vehicle damage costs, and potential medical bills, none of which your general liability policy is designed to cover either.

Here’s the thing: smaller contractors who start out using personal vehicles often never make the switch to commercial coverage. Some believe a personal policy with high limits is adequate. It isn’t. Commercial auto policies differ in how they classify vehicles, define business use, and extend coverage to hired or non-owned vehicles. And if any of your employees occasionally use their own cars for work purposes (picking up supplies, running to a second job site), you may also need hired and non-owned auto coverage as a separate line item. Don’t assume your current policy stretches to cover those situations.

Contractual Liability You Agreed To But Didn’t Cover

Every time you sign a contract with a general contractor, property owner, or developer, you’re likely agreeing to indemnify them against claims arising from your work. Most contractors sign these agreements without thinking twice. The issue is that standard GL policies cover your own liability, not the liability you’ve assumed on someone else’s behalf through a contract. If you agree to hold a GC harmless and a claim later arises, your insurer may argue that the contractual obligation isn’t covered under your base policy.

The coverage that addresses this is called contractual liability coverage, and it’s sometimes included in GL policies but often limited in scope. Blanket additional insured endorsements can also help, but only if they’re structured correctly and match what the contract actually requires. So before you sign any indemnification clause, it’s worth having your agent review the contract language against your current policy; mismatches between what you agreed to and what your policy actually covers are one of the more expensive surprises in contractor insurance, and they tend to surface at the worst possible time, after a loss has already occurred.

Conclusion

The hidden risks most contractors don’t realize they’re not covered for aren’t obscure technicalities. They’re gaps that show up in everyday work situations: faulty installs, signed contracts, a worker driving to a job site. Review your policy language carefully. Ask your agent specific questions about exclusions. Verify coverage before a project starts, not after a claim is filed.
