Ohio Plumber Contractor Insurance

You finished the job. Everything looked good. Customer signed off. You moved on.

Three months later a pipe bursts. Water damage spreads through the property. The claim comes back to you.

You call your agent. That's when you find out your policy has a completed operations exclusion. The work is done, so the coverage is gone. You're on your own for a loss that happened on a job you finished months ago.

This isn't rare. It happens to plumbers across Ohio every year. And it happens because an agent sold them a policy without explaining what it actually covers.

At Equilibrium Insurance Partners, we're Certified Insurance Counselors (CIC). We review your policy language, not just your premium. We make sure your completed operations coverage is in place before you ever need it.

There's a difference. You'll know exactly what that difference is when a claim comes in three months after the job is done.

Plumbing contractor insurance isn't one policy. It's a program built around the specific risks of plumbing work across residential, commercial, and industrial properties.

You're working inside occupied buildings, behind walls, under slabs, and in mechanical rooms. You're handling water lines, gas lines, drain systems, and pressurized equipment. One failure, a burst pipe, a gas leak, a faulty connection, can cause catastrophic property damage or bodily injury.

Ohio requires plumbing contractors to carry liability coverage to maintain licensure. But minimum coverage isn't the same as real protection. Most plumbers we talk to have policies that satisfy state requirements on paper while leaving real gaps in actual protection.



General Liability Insurance

Your foundation. General liability covers bodily injury and property damage resulting from your operations. You damage a customer's property during installation. A fitting fails and causes water damage. Someone is injured on a job site you're working on. General liability responds.

What most agents won't tell you: plumbing policies have trade-specific exclusions that vary by carrier. Completed operations exclusions. Water damage sublimits. Work performed on certain property types. If your agent never reviewed your policy language with you, there's a real chance you have gaps you don't know about.

Minimum recommended limits for Ohio plumbing contractors are $1,000,000 per occurrence and $2,000,000 aggregate. Commercial and industrial property managers typically require at least this and often more.

Completed Operations Coverage

This is the one most plumbers don't know they're missing until it's too late.

Completed operations coverage extends your general liability protection after the job is finished. If your work causes damage six months after completion, completed operations is what responds.

Without it, your coverage stops the moment you leave the job site. For plumbers, that's a serious gap. Water damage from a faulty installation can take weeks or months to show up. By the time the claim comes in, your standard policy may have nothing left to offer.

Verify your completed operations coverage before your next renewal. Don't assume it's there.

Workers' Compensation

If you have employees in Ohio, workers' comp is required by law. Ohio is a monopolistic state, meaning you purchase through the Bureau of Workers' Compensation (BWC), not a private carrier.

Plumbing work carries real injury risk. Confined spaces, heavy pipe, trenching, and exposure to hazardous materials. Your classification codes need to accurately reflect the work your employees are doing. Misclassified employees are one of the most common causes of audit surprises we see.

Get your classifications right upfront. It protects you at audit and keeps your premiums predictable year over year.

Commercial Auto

Your service vans, trucks, and pipe haulers need commercial auto coverage. Not personal auto. If one of your plumbers is in an accident on the way to a job and you're relying on personal auto policies, you're likely uninsured for that loss.

Hired and non-owned auto coverage matters too if your employees use personal vehicles for work. Most plumbing contractors don't think about this until there's a claim.

Inland Marine / Tools and Equipment

Your tools, pipe threading equipment, and specialty plumbing equipment are not covered under general liability. They're not covered under commercial property when they're off site. Inland marine coverage protects your gear on job sites, in transit, and in your vehicles.

One van break-in or equipment theft can cost tens of thousands of dollars out of pocket without it.

If you're installing larger fixtures like commercial water heaters or boilers, that equipment belongs to the customer, not you, and standard tools and equipment coverage doesn't extend to it while it's staged on site awaiting installation. An installation floater covers that gap.

Commercial Umbrella

Commercial and industrial property managers increasingly require $3 million, $4 million, or more in total liability limits. An umbrella policy sits above your general liability and commercial auto and extends your limits at a fraction of the cost of increasing underlying limits.

If you're working on commercial or industrial properties, you need an umbrella. It's often a requirement before you can get on an approved vendor list.

This is where plumbing contractors run into real complexity.

You're not working for one customer with one set of insurance requirements. You're working across multiple property management companies, commercial property owners, and industrial facilities. Each with their own certificate requirements, additional insured language, and minimum limits.

One property manager requires $1M/$2M with primary and non-contributory. Another requires $2M/$4M with a waiver of subrogation. A third has a vendor approval process that requires specific endorsements before you can work on their properties.

Sending the wrong certificate to the wrong property manager, missing an endorsement, or carrying limits that don't meet a specific contract can get you pulled from a vendor list. Or leave you uninsured on a job.

We help plumbing contractors navigate this. We know what the major property management companies in Ohio require. We build your policy so it satisfies the broadest set of requirements across your client base. And when a new property manager sends you their requirements, we review them and tell you exactly where you stand.
