Quick Answer: Plumber insurance combines general liability, workers compensation, tools and equipment, and commercial auto into one program. Most plumbing contractors pay around $115 per month for general liability, with full packages scaling by payroll, crew size, and the mix of service, commercial, and new-construction work. Water damage is the defining plumbing exposure, so coverage limits and completed operations matter more here than in most trades. Licensing bonds are a separate requirement, and most contracts demand proof of both.
Water is unforgiving. A small leak becomes a major loss, mold shows up fast, and one failed fitting can flood an entire floor. Fair or not, plumbers are often blamed even when the water issue was not their fault, and a defect can surface long after the job is done. As an independent brokerage, Pro Insurance Group shops your plumbing coverage across 20-plus carriers that actively write the trade, so you carry the right protection at a competitive rate, with the documentation builders, property managers, and municipalities actually require. Here is how the coverage works and what it costs.
Coverages for Plumbing Contractors
General Liability
Pays for third-party bodily injury and water or property damage claims, the most common and most expensive losses plumbers face. Often required at $1M per occurrence.
Workers Compensation
Covers slips, cuts, burns from soldering and brazing, and confined-space or trench injuries. Required by law in most states once you hire your first tech.
Tools and Equipment
Inland marine coverage for pipe threaders, drain machines, press tools, jetters, cameras, and torches when stolen or damaged, wherever the gear travels.
Commercial Auto
Covers your service vans and trucks, including Hired and Non-Owned Auto for when employees use personal vehicles on service runs.
Completed Operations and Pollution
Protects you when a fitting fails or a sewer line backs up after the job, including contamination exposure from sewer, drain, and hydro-jetting work.
Commercial Umbrella
Adds $1M to $10M or more above your liability and auto limits, frequently required for commercial, school district, and government plumbing contracts.
Why Every Plumbing Contractor Needs Coverage
Plumbing carries one risk that defines the whole trade: water. A failed fitting, an unnoticed pinhole, or a pressure problem after you leave can trigger a six-figure cleanup, and you will likely be named in the claim. According to the Bureau of Labor Statistics, plumbers also face above-average rates of on-the-job injury from burns, cuts, and confined-space work. The right program covers all of it: the water damage, the injured tech, the stolen jetter, and the defect that surfaces a year later. Sewer, drain, and hydro-jetting work add a contamination exposure that makes pollution liability worth a serious look.

Plumber Insurance FAQ
Do I need plumber insurance?
Yes. In most states, proof of general liability is required to hold a plumbing license, sign a commercial lease, or start a job, and workers compensation is required by law once you have employees. Even a solo plumber needs coverage, because a single water-damage claim can exceed what most businesses can absorb out of pocket.
What insurance does a plumbing contractor need?
Most plumbers need general liability, workers compensation, commercial auto, and tools and equipment coverage. Commercial and new-construction plumbers usually add a commercial umbrella, completed operations, and pollution coverage for sewer and drain work.
How much does plumber insurance cost?
A solo plumber often pays $95 to $160 per month for general liability, while a small crew running a full program with workers comp and commercial auto typically runs $250 to $500 per month. Cost depends on payroll, the type of plumbing work, vehicles, equipment value, water-damage exposure, and claims history.
Do you provide same-day certificates of insurance?
Yes. Most certificates are issued the same day, often within hours. Upload your contract or permit requirements and we will match the wording, including Additional Insured, Waiver of Subrogation, and Primary and Non-Contributory.
Do you insure plumbing subcontractors and sole proprietors?
Yes, from one-person operations to multi-crew commercial plumbers. We tailor the program to your size and the mix of service, remodel, and new-construction work you perform.
Does my homeowners insurance cover plumbing?
This page is for plumbing contractors buying business coverage. If you are a homeowner asking whether your policy covers a plumbing problem, that is a personal lines question, and the answer depends on the cause. Sudden accidental water damage is often covered while gradual leaks usually are not. See our home insurance page, and always ask any plumber you hire for a certificate showing active general liability and workers compensation.
