General Liability

• Third-party bodily injury and property damage from your plumbing work
• Client injuries at your shop or on a job site
• Products & Completed Operations - covers water damage claims that surface after the job is finished
• Personal and advertising injury (libel, slander)
• Additional Insured endorsements for GCs and property owners on permitted work
• Primary & Noncontributory and per-project aggregate as required by GC contracts

A failed connection that floods multiple units weeks after a job is the classic plumber's claim. Completed Operations coverage is what responds - confirm your limits are adequate, as water damage claims can escalate quickly.

Errors & Omissions (Professional Liability)

• Claims alleging design or sizing errors on larger commercial plumbing systems
• Pipe sizing, venting, or backflow prevention design mistakes
• Relevant for plumbers providing system design or engineering-adjacent services
• Covers defense costs and damages separate from the physical-loss claims GL handles

Most residential repair work is adequately covered by GL's Completed Operations. E&O becomes relevant when you're sizing a system for a commercial build-out or designing a backflow prevention system.

Inland Marine (Tools & Equipment)

• Pipe benders, sewer testing systems, cameras, and power tools
• Coverage follows tools to job sites - not just your shop or vehicle
• Theft, damage, and mysterious disappearance at client locations
• Scheduled coverage for high-value equipment (sewer cameras, jetters)

Standard Commercial Property covers tools only at your listed business address. Inland Marine protects your tools at every job site, which are often expensive to replace and targeted for theft.

Builder's Risk

• Covers plumbing materials and unfinished rough-in work while a larger construction project is underway
• Applies when you're a sub on a ground-up build or major renovation
• Covers materials staged on-site before installation
• Typically arranged by the GC, but confirm your interest is properly reflected

If you're plumbing a new building or major renovation, confirm whether the GC's Builders Risk policy covers your installed work and staged materials.

Commercial Auto

• Service vans and trucks carrying tools, fittings, and replacement parts
• Liability for accidents on highways and city streets
• Hired & Non-Owned Auto for employees using personal vehicles for parts runs
• Physical damage coverage for owned vehicles and their tool inventory

A service van is often a rolling parts and tool inventory worth thousands. Confirm whether tools and stock inside the vehicle are covered under Auto, Inland Marine, or both.

Workers' Compensation

• Required by NC law for any business with employees
• Medical bills and lost wages for back injuries, cuts, burns, and confined-space incidents
• Covers apprentices and journeyman plumbers alike
• Employers Liability protects against employee negligence suits
• Non-compliance fines can be significant; NC DOL actively audits contractors

Plumbing work carries elevated injury risk. Accurate payroll classification and a documented safety program help manage WC costs in this trade.

License & Permit Bonds

• Required by NC and many municipalities as a condition of contractor licensing
• Guarantees your work complies with code and licensing regulations
• Distinct from insurance - a bond protects the public, not your business
• Bid, performance, and payment bonds also available for larger commercial plumbing contracts

North Carolina's permitting process for plumbing work typically requires proof of a current license and bond before a permit is issued.

Business Income & Commercial Umbrella

• Business Income: replaces lost revenue if your shop or storage facility is damaged by a covered loss
• Commercial Umbrella: adds $1M-$10M+ excess liability above your GL, Auto, and Employers Liability
• Umbrella often required by GCs and commercial property owners for larger projects
• Cost-effective way to reach the higher limits commercial contracts specify

A serious multi-unit water damage claim can exceed a $1M GL limit quickly. An umbrella is one of the most cost-effective ways to protect against that exposure.

NC State Board of Examiners of Plumbing

North Carolina requires a plumbing license to perform plumbing work for compensation, administered by the State Board of Examiners of Plumbing. Both individual licensure (journeyman/master exams) and business licensure are required. Proof of liability insurance is a condition of business license issuance and renewal - a lapse in coverage can jeopardize your license status.

North Carolina Plumbing Permits

Plumbing work in North Carolina requires permits issued through local building departments, with inspections required before work is closed up or put into service. Permit applications typically require proof of your current plumbing license, a license/permit bond, and Certificate of Insurance. Failure to permit plumbing work can result in fines and can void insurance coverage if a claim arises from unpermitted work.

NC Backflow Prevention Regulations

North Carolina requires backflow prevention devices on qualifying water service connections to protect the public water supply. Testing and certification of backflow devices is typically required annually for commercial and many multi-family buildings. Confirm your GL covers liability arising from backflow testing and installation work specifically, as some carriers treat it as a distinct operation.

NC Worker Classification

North Carolina applies specific tests to determine whether a worker is an employee or independent contractor. Many plumbing businesses rely on subcontracted journeymen or helpers; misclassifying them can trigger Workers' Compensation back-premium assessments, wage and hour penalties, and tax liability. The NC DOL actively audits contractors - review your worker classifications before an audit, not after.
