Common questions about plumbing insurance

Find answers to frequently asked questions about plumbing contractors' insurance requirements and licensing.

Does plumbing liability insurance protect against faulty work claims?

Plumbing liability insurance provides important coverage, but it’s critical to understand its limitations, especially when it comes to errors in workmanship.

General liability coverage often covers third-party property damage or bodily injury. However, many policies include a “your work” exclusion, which means the cost to fix the actual plumbing work itself may not be covered if an error or defect occurs during installation or repair.

Professional indemnity insurance, often called professional liability insurance, helps pay for customer lawsuits stemming from an accusation of professional negligence. That includes mistakes, oversights, and missed deadlines that financially impact a customer.

For example, if an improperly installed water heater leaks and damages a basement and its contents. The customer could sue the plumber for the cost of fixing the water damage, including flooring repairs, new pipes, and mold remediation.

Professional indemnity insurance covers things such as:

  • Professional negligence
  • Breach of confidentiality
  • Missed deadlines and undelivered services
  • Contract breaches
  • Oversights and errors
  • Inaccurate professional advice

Though state laws don't always require it, professional liability insurance is especially valuable for plumbers who provide diagnostic, installation, or design-related services.

Human error is inevitable no matter how careful you may be, and the out-of-pocket costs of legal action can be high. Professional liability insurance protects your business if a customer sues over dissatisfaction.

What other insurance policies do plumbers need?

Beyond those mentioned above, a wide range of plumbing insurance policies can match your business's specific needs.

Plumbing professionals, including sole proprietors, should consider the following policies:

  • Builder's risk insurance covers a structure being built at a construction site, along with pipes and other materials. It's also called course of construction insurance.
  • Commercial property insurance covers your office building and everything in it, including computers, tools, and furniture. It helps you recover after a fire, storm, or burglary.
  • Business personal property (BPP) insurance can be added to your general liability policy as an endorsement to cover business property kept at a fixed location, such as your office.
  • Installation floater coverage protects materials, fixtures, and supplies while they are being transported, stored off-site, or installed at a jobsite, helping close key gaps during active plumbing projects. You may also see this policy called inland marine insurance.
  • Commercial umbrella insurance boosts the coverage on your general liability, commercial auto, and employer's liability insurance once the policy limit is reached.
  • Business interruption insurance, also called business income insurance, covers day-to-day operating costs and lost income resulting from a fire or other covered property claim. You can usually add it to your property policy or BOP.
  • Hired and non-owned auto (HNOA) insurance provides liability coverage when you or your employees use a personal, leased, or rented vehicle for business purposes.
  • Cyber insurance, also referred to as cybersecurity or cyber liability insurance, is recommended for businesses that handle personal information, such as credit card numbers and email addresses. It covers the steep costs of a data breach, including customer notification, credit monitoring, legal fees, and fines.
  • Contractors pollution liability insurance (CPL) protects contractors against pollution-related legal costs, such as a lawsuit over excessive dust at your construction site.

Do plumbers need a license, permit, or bond?

Plumbers often need licenses, permits, and bonds to work legally or to take on certain projects.

Some states, for example, require separate licenses for sewer contractors, septic system contractors, drainage installers, or specialists who work with sump pumps and water pumps. Other states allow broader plumbing licenses that cover multiple services.

Here's a quick breakdown:

  • Licenses: Most states require plumbers to get licensed in order to do paid work on their own. You usually need a certain amount of education and experience and must pay a licensing fee.
  • Permits: For anything beyond minor repairs, you likely need a permit from your county or other municipality. That's especially true if you're installing new lines or doing plumbing work that connects to a city's sewer line or other municipal system.
  • Bonds: Bonds are often part of the state licensing requirements for plumbers. You might also need a bond to bid on a public works project or sign a contract with a client.

Proper licensing, bonding, insurance, and permits show clients you run a legitimate, reputable business, which is essential when you're bidding on plumbing jobs.

Many homeowners or commercial clients require proof of coverage before hiring a plumber, so quickly providing a certificate of insurance (COI) can be the difference between getting (or losing) a contract.

Plumbing businesses often need a license, permit, bond, and plumber liability insurance in order to do their work legally. This helps you avoid penalties and protects you financially if you face a lawsuit.

It'll take a little research to learn the regulations for your area. In addition, most states require workers' compensation insurance when you have employees, and commercial auto insurance for business-owned vehicles.

Many plumbers also need to obtain a subcontractor certification, as general contractors often require proof that anyone working under them meets certain licensing and insurance standards.
