Plumbing Contractor Insurance

Insurance built for plumbing contractors.

Plumbing Guard Insurance insures the business owners of plumbing companies across the way they work — the residential crews on service, repair, and remodel jobs in occupied homes, and the commercial contractors running systems, backflow programs, gas lines, and new construction at scale. One specialty program built around the exposures a generic policy leaves out: water damage on completed work, sewage and pollution, gas lines, and a crew in trenches and confined spaces.

Coverage for plumbing contractors

The core lines a plumbing business carries — led by the two that define this class: general liability built around water-damage completed operations, and pollution liability for the sewage, contaminant, and gas exposures a standard policy excludes.

General Liability Insurance

Third-party bodily injury and property damage coverage for plumbing contractors — built around products-completed-operations, where a failed fitting, connection, or valve on completed work floods a finished space weeks or months after the job (the plumbing trade’s defining GL exposure), plus the severity of gas line work. The signature general liability page for the plumbing trade.

Pollution Liability Insurance

Coverage for sewage backup and release, contaminant discharge during drain and sewer work, and fuel or gas line incidents — the pollution exposures the standard general liability pollution exclusion carves out, which is exactly why this line matters for plumbing contractors. A signature line for the plumbing trade.

Workers Compensation Insurance

Medical and lost-wage coverage for plumbing crews — with honest handling of the four monopolistic state-fund states and the trench, excavation, confined-space, and scald and burn exposures that shape a plumbing operation’s injury profile.

Learn more →

Commercial Auto Insurance

Coverage for the service trucks and vans a plumbing operation runs between the shop and the jobsite — the mobile, truck-roll trade of a fleet that hauls plumbers, tools, fixtures, and materials on the road every working day.

Learn more →

Contractors Equipment Insurance

Inland marine coverage for the tools, equipment, and materials a plumbing contractor owns — on the jobsite, in the yard, and in transit — from hand tools and pipe threaders to sewer cameras, pipe locators, drain machines, and the fixtures staged for the next install.

Umbrella Liability Insurance

Excess limits above general liability, commercial auto, and other underlying policies for plumbing contractors — and the higher limits that general contractors, developers, and project contracts often require of their plumbing subcontractors.

Professional Liability Insurance

Plumbing errors-and-omissions coverage for the design, specification, and consulting side of the work — the financial-loss exposure from a professional judgment, a system design, or advice that goes wrong, distinct from the faulty-workmanship exposure general liability addresses. The seam between the two is stated crisply.

Built for how plumbing businesses actually carry risk

The signature exposures of this trade are the water your work leaves behind and the sewage, contaminant, and gas releases that come with drain and gas-line work — not just the slip-and-fall a generic policy is priced for.

A leak that shows up in a finished space weeks after the job is the exposure that defines this trade

The biggest risk on completed plumbing work is not a slip on the jobsite — it is a fitting, connection, or valve that fails after the crew has left and floods a finished space, causing third-party property damage downstream. That is the products-completed-operations side of general liability, and on plumbing it is the exposure that matters most. It is joined by the severity of gas line work, where a failure carries consequences well beyond a water loss. We build the general liability program around both.

Sewage and contaminants are a pollution exposure your general liability quietly excludes

Drain, sewer, and gas work carries a pollution exposure that many contractors are running uncovered: a sewage backup or release, a contaminant discharge, or a fuel or gas incident. The standard general liability policy carves these out through its pollution exclusion — which is exactly why a dedicated pollution liability line matters for a plumbing operation. We treat it as a core part of the program rather than an afterthought, and we walk owners through where the general liability policy stops and the pollution line begins.

Plumbing contractor insurance FAQ

Does general liability cover water damage from a leak after I finish the job?

That is the products-completed-operations side of general liability, and on completed plumbing work it is the exposure that matters most. A fitting, connection, or valve you installed or repaired that later fails and floods a finished space, causing third-party property damage, is what this part of the policy is built to respond to. How the policy is triggered — on an occurrence basis versus a claims-made basis — changes how a claim that surfaces months after the job is finished is handled, which is exactly the nuance we walk owners through.

Does my general liability cover a sewage backup or a contaminant release?

Usually not on its own. The standard general liability policy carves out sewage backups, contaminant discharges, and fuel or gas incidents through its pollution exclusion — the exact exposures drain, sewer, and gas work create. That is why a dedicated pollution liability line matters for a plumbing operation. We walk owners through where the general liability policy stops and the pollution line begins, so the gap is covered rather than discovered after a loss.

What is employers liability, and how does it relate to workers comp and umbrella?

Employers liability is the part of a workers compensation policy that responds when an injured employee brings a suit that falls outside the no-fault comp benefit itself. It sits alongside the medical-and-wage benefit, and an umbrella policy can sit excess of it. For a plumbing crew working in trenches, confined spaces, and around scald and burn hazards, it is a meaningful part of how the program is structured — not a line item to ignore.

Are my service trucks, tools, and equipment covered on the road and on the jobsite?

Those are two different lines. Commercial auto answers the service trucks and vans that run between the shop and the jobsite every working day — the mobile, truck-roll exposure a personal or generic policy is not built for. Contractors equipment, an inland marine line, answers the tools, sewer cameras, pipe locators, drain machines, and staged fixtures on the jobsite and in transit. A plumbing program should carry both, matched to how you actually run the operation.

Do plumbers need a license?

In most states, yes — plumbing is among the most-licensed trades, usually through journeyman and master tiers issued by a state plumbing board. Some states run licensing at the state level, and some defer to local jurisdictions. Because it varies, the honest answer is state-by-state — we confirm what your specific state and locality require rather than assuming a single national rule, and we never point you at a license or tier that does not exist.

How much does plumbing contractor insurance cost?

There is no single price, because premium is driven by your specific operation. The biggest factors are your payroll and crew classifications, your revenue, the mix of work you do — residential service and remodel versus commercial systems and new construction — whether you run drain, sewer, or gas lines, the number and value of your service trucks, and your prior claims history. A residential service shop and a commercial new-construction contractor look very different to an underwriter. We price to the real risk rather than a generic guess.

Who we are

Plumbing Guard Insurance is a specialty brand of Wexford Insurance, an independent agency led by Nate Jones, CPCU. We focus on one class — plumbing contractors, across residential service and remodel and commercial systems and new construction — and place coverage with carriers that actually want the work.

Plumbing contractors don’t fit a generic business policy. The work you leave behind is the risk — a fitting that fails and floods a finished space is a completed-operations claim — and the sewage and gas exposures that come with drain and gas-line work are a pollution question a standard policy quietly excludes. We built Plumbing Guard because the coverage has to match how a plumber actually operates, whether that’s residential service and remodel work or commercial systems and new construction, not a one-size-fits-all form.
