Independent insurance guidance from our Madisonville office for businesses across Texas.
Do I need insurance to run a plumbing business in Texas?
Texas licenses plumbers through the Texas State Board of Plumbing Examiners. Before a master plumber can act as the Responsible Master Plumber for a plumbing company, Texas law requires a certificate of insurance on file with the Board. That certificate must show commercial general liability coverage of at least $300,000 for all claims in a one year period, covering property damage or bodily injury, whether the claim comes from negligence or from a contract.
This requirement is tied to the Responsible Master Plumber, the individual in charge of a plumbing company's licensed work, not to every plumber on staff. Texas also licenses tradesman plumbers, journeyman plumbers, and master plumbers, and the insurance rule is not stated as a separate requirement for those license types.
Workers compensation is a separate question from the insurance certificate above. Texas does not require most private employers, including most plumbing businesses, to carry it, so coverage is elective in most cases. An exception applies on a government building or construction contract, where the contractor must certify to the government entity that it provides workers compensation coverage for its employees on that job.

If you run service calls and repairs
Most Texas plumbing businesses spend their days on service calls and repairs: water heaters, leaks, drain cleaning, fixture replacement, and remodel plumbing in homes and businesses.
Gas line work and remodel plumbing fit inside this audience too. Tell us about the mix of jobs your crews run so we can review the right coverage questions with you.
If you take on new construction or larger commercial work
Some plumbing businesses also take on new construction plumbing or larger commercial projects, including work tied to a government building or construction contract. Bring that work to us.
A licensed team member looks at the details first, including any government contract requirements, before we talk about markets or a quote.
What insurance does a plumbing business need?
Every plumbing business is different. Review these exposures with a licensed agent before you assume what is included.
Service vehicles
Commercial auto may address covered accidents involving service trucks and vans. Check liability and vehicle-damage coverage separately, and review rented or employee-owned vehicles used for parts runs or other work.
Tools and shop equipment
Equipment or inland marine coverage may help with covered theft or damage to tools away from the shop. Include leased and technician-owned items and check overnight-storage conditions, deductibles and limits.
People on the crew
Workers compensation can help with covered work-related injuries to employees. Include apprentices and subcontractor arrangements, and check any coverage required by the job contract.
Completed work
Products or completed operations coverage within general liability may address covered injury or damage caused by finished work. It does not automatically pay to redo a faulty repair or installation. Check exclusions and the completed-operations limit.
Specialty and gas work
LP gas, medical gas and fire protection sprinkler work need a specific check of the work accepted by the insurer and any exclusions or endorsements. Bring the applicable license details and the exact services performed.
Customer property
General liability may address covered damage to a customer's other property, such as water damage following a repair. The particular property being worked on and the cost of correcting your work may be excluded.
What is the difference between general liability and completed operations?
Commercial general liability commonly includes protection for both ongoing work and products or completed operations. Check the specific policy and endorsements when comparing quotes.
General liability
Commercial general liability can address covered claims of bodily injury or property damage arising from your business. It commonly includes ongoing operations and products or completed operations, subject to the policy's limits and exclusions.
Completed operations
Products or completed operations is commonly part of general liability. It concerns injury or damage caused by finished work, such as water damage from a fitting after a job is complete. Coverage depends on the policy; the date a claim is reported alone does not decide it.
Responsible Master Plumber
The Responsible Master Plumber is the master plumber who takes responsibility for a plumbing company's licensed work with the Texas State Board of Plumbing Examiners, including keeping its certificate of insurance on file.
How much does plumbing insurance cost in Texas?
Cost depends on the size and mix of your plumbing business: how many vehicles you run, how many employees and subcontractors work with you, and whether your jobs lean toward service and repair or new construction.
Payroll, annual revenue, prior claims, the value of your tools and equipment, and whether your business holds its own Responsible Master Plumber designation all factor in too. A licensed review is the only way to see how these apply to your business.
Before you compare the price
- Vehicle and equipment limits
Check that each quote lists the same vehicles and values your tools and equipment the same way.
- Liability and completed operations
Confirm whether general liability and completed operations are both included, and at what limits.
- Employee and subcontractor coverage
Ask how each quote treats employees, apprentices, and any subcontractors you use.
- Deductibles and exclusions
Compare what each policy excludes and what you would pay out of pocket before it responds.

Common questions from Texas plumbing business owners
Do I need insurance to run a plumbing business in Texas?
Texas requires a certificate of insurance for the Responsible Master Plumber named on a plumbing company's license, on file with the Texas State Board of Plumbing Examiners. Under Texas Occupations Code sections 1301.3576 and 1301.552, that certificate must show commercial general liability coverage of at least $300,000 for all claims in a one year period. The requirement is tied to the Responsible Master Plumber, not to every plumber working for the company.
Does the insurance requirement apply to every plumber, or only the Responsible Master Plumber?
The certificate of insurance requirement is tied to the Responsible Master Plumber named on a company's license, not to every individual plumber. Texas licenses other roles, including tradesman plumber, journeyman plumber, and master plumber, and the insurance rule is not stated as a separate requirement for those license types. If your business has more than one licensed plumber, ask us who holds the Responsible Master Plumber role.
Is workers compensation required for a Texas plumbing business?
Texas does not require most private employers, including most plumbing businesses, to carry workers compensation, so coverage is elective in most cases. An exception applies on a government building or construction contract, where the contractor must certify to the government entity that it provides workers compensation coverage for its employees on that job. Ask us how this applies if you take on public project work.
What is the difference between general liability and completed operations?
Products or completed operations is commonly included within commercial general liability. It concerns injury or damage caused by finished work. Check exclusions, limits, endorsements, and the policy's coverage trigger before assuming a particular loss is covered.
Will general liability cover a customer's water damage after a repair?
It depends on the damage, the work, and the policy. Resulting damage to other property and the cost of correcting your own faulty work can be treated differently. Bring the job and damage timeline so a licensed team member can review the terms and endorsements; the claim-reporting date alone does not decide coverage.
What changes the cost of plumbing business insurance?
Cost depends on the size and mix of your business: vehicles, employees and subcontractors, payroll, annual revenue, and whether your work leans toward service and repair or new construction. Prior claims, tools and equipment values, and your Responsible Master Plumber arrangement matter too. A licensed review is the only way to see how these apply to you.
