What plumbing insurance actually covers

Plumbing insurance isn't one policy. It's a set of policies built around the ways a plumbing business gets hurt. The biggest ones look like this.

Water damage you didn't mean to cause

A lot of plumber liability claims start with water. A supply line you replaced lets go two weeks later. A PEX connection under a vanity weeps into a subfloor for a month before anyone notices. General liability, including the completed operations part of the policy, is what usually responds to damage to the customer's property. The cost to redo your own work is a different story, and many policies don't cover it. We walk through the difference on the general liability page.

Your vans and the people driving them

Your service van is a rolling warehouse that spends all day in traffic. A personal auto policy usually won't cover a vehicle used for business, so plumbing vans and trucks need commercial auto insurance. The tools inside need their own coverage.

Injuries on the crew

Plumbing is physical work in tight spaces: crawlspaces, trenches, attics, mechanical rooms. Workers' comp pays medical bills and lost wages when a tech gets hurt, and most states require it once you have employees. The rules differ by state, so we cover each one on its state page.

Sewer, mold and the exclusions that surprise people

Sewer backups, mold and bacteria are exactly the kinds of losses many general liability policies limit or exclude. If you do drain, sewer or remediation-adjacent work, contractor pollution liability is how you close that gap.

Tools that walk away

A loaded service van can carry a drain machine, a sewer camera, a press tool kit and a few thousand dollars of fittings and valves. Thieves know it. Commercial auto usually covers the van, not what's on the shelves inside it. A contractor's equipment policy, sometimes called an inland marine floater, is what typically pays to replace stolen or damaged tools so you can get back on the road. The details matter here, so ask before you buy: what does the policy require for theft from a parked van, and will older tools be paid at replacement cost or at their depreciated value? See how tools coverage works.

The paperwork that wins jobs

Insurance isn't only about claims. For a growing plumbing business, it's also the paperwork that gets you through the gate. General contractors, property managers, school districts and hospitals often won't let you start until they see a certificate of insurance showing the right limits, their name as an additional insured and sometimes a waiver of subrogation. If your policy doesn't have the right endorsements, a certificate alone won't fix it, and the job can go to someone else while you wait. We set up your coverage with the right endorsements ahead of time, and once you're a client, certificates on your existing coverage are available the same day. A request from a GC becomes a quick turnaround instead of a week-long scramble.

Who we insure

Different kinds of plumbing work carry different risks. Coverage should match the work you actually do.

Coverage that grows with your shop

Most plumbing businesses don't outgrow their trade. They outgrow their insurance. These are the moments when your coverage needs to change, usually before anyone tells you.

What drives the cost of plumber insurance

Two plumbing businesses of the same size can pay very different premiums. Carriers price your coverage mainly on:

• Payroll and revenue. Workers' comp is usually rated on payroll, and general liability is often rated on revenue or payroll.
• The work you do. Service and repair, new construction, sewer and excavation, and commercial work are priced differently.
• Your claims history. A clean loss record is one of the strongest things you can bring to a quote.
• Vehicles and drivers. The number of vans, their values, and your drivers' records.
• Limits and deductibles. Higher limits cost more. Higher deductibles usually cost less.
• Your state. Workers' comp rates, auto rates and legal climate vary by state.

Where you shop matters too. Carriers price the same plumbing business differently, and a captive agent can only show you one of them. Because we're independent, your information goes to several carriers, and you see how they compare instead of taking the first number you're given. If a carrier won't write a certain kind of work, like sewer excavation or a business with less than three years of history, we know which carriers are more likely to say yes.
