Who needs plumbing insurance?

Plumbing professionals who should have insurance coverage include:

  • Plumbing contractors and business owners.

  • Septic system workers.

  • Piping contractors.

  • Sprinkler installers.

Your city or state may require that you carry an insurance policy in order to start work on a residential or commercial project. Some states, like Florida and Ohio, may also require that you purchase business insurance to get your plumbing license.

Clients may ask for proof of insurance coverage, such as a certificate of liability insurance, before agreeing to work with you or your business.

What types of insurance do plumbers need?

At a minimum, plumbers should have general liability insurance to protect against third-party claims of bodily injury or property damage. Additional coverage — such as professional liability insurance, business property insurance and commercial auto insurance — may be beneficial as well, depending on the individual business and its level of risk.

Here are some of the different types of plumbing insurance you might consider, and what these policies typically cover.

Type of insurance

What it covers

Claims of third-party bodily injury, property damage and personal and advertising injury.

If a client trips over a pipe you put on the floor while repairing a sink and breaks their wrist, this policy would cover their medical expenses, as well as any legal or settlement fees if they file a lawsuit against you.

This policy would also cover the cost to replace a client’s bathroom mirror if it shatters while you’re trying to repair the sink.

Claims of professional negligence, error, breach of contract or failure to deliver a service on time.

If you’re installing plumbing for a house remodel and make a mistake in the installation that causes the system to fail, the owner could sue you for the error. This policy would cover your legal and settlement costs associated with the lawsuit.

Business property or buildings that are damaged by certain accidents, weather events or other hazards.

If a fire breaks out in your office and destroys all of your plumbing equipment, your business property insurance would cover the costs to replace it.

Medical expenses of employees who are injured or get sick while at work.

Most U.S. states require employers to have workers' comp for their employees. If one of your plumbers falls off a ladder while fixing a pipe and dislocates a shoulder, your workers’ compensation policy would cover any related medical expenses.

Vehicles that you use for business purposes, such as driving to plumbing projects.

Covers accident-related expenses resulting from injuries, death or property damage.

If you’re driving your work van to pick up supplies and accidentally hit a car in the store’s parking lot, this policy would pay to repair the damage to the car.

Claims of physical injury or property damage as a result of a defective or flawed product, such as pipes, tubes or tanks.

If you install a new pipe in a kitchen sink, and a defect in the pipe causes the pipe to break and the sink to flood the kitchen — your customer could sue you for the damage to their kitchen.

Your product liability insurance would cover the cost to repair the kitchen, as well as legal and settlement costs.

Tools and equipment insurance

Cost to repair or replace equipment that is damaged or stolen. You can sometimes add this coverage to another type of policy, like your general liability insurance.

You might also choose to bundle multiple types of plumbing insurance into a business owner’s policy, or BOP. Generally, BOPs include general liability insurance, commercial property insurance and sometimes business interruption insurance — but they can also be customized to meet your business’s needs.

How much does plumbing insurance cost?

The cost of your plumbing insurance will depend on a variety of factors such as:

  • Business location.

  • Number of employees.

  • Nature of your plumbing work/types of projects your work on.

  • Claims history.

  • Number of policies.

  • Amount of coverage.

In general, the more coverage you need, the higher the cost of your business insurance will be. For example, a self-employed plumbing contractor who only needs general liability and professional liability insurance will pay less for a policy than a multi-employee business that needs these types of insurance, as well as workers’ compensation and commercial auto insurance.

The best way to get an idea of how much a policy will cost is to get a customized quote for your business.
