A single sewer line excavation gone wrong can cost your Ohio contracting business hundreds of thousands of dollars. Picture this: your crew hits an unmarked gas line while repairing a collapsed sewer main in Columbus. The resulting damage shuts down a city block, injures a worker, and triggers lawsuits from three property owners. Without proper insurance coverage, this scenario could bankrupt even an established firm. Ohio sewer line repair specialists face unique risks that general contractors don't encounter, from pollution exposure during sewage backflows to equipment damage in unstable trenches. This insurance coverage guide walks you through the specific policies you need, the Ohio regulations you must follow, and the strategies that protect your business from catastrophic losses. Whether you're a solo operator with a camera inspection van or a mid-sized firm running multiple excavation crews, understanding your coverage options isn't optional. It's the difference between surviving a major claim and closing your doors.
Core Liability Coverage for Sewer Specialists
Every sewer line repair business needs a foundation of liability coverage tailored to underground work. Generic policies written for general contractors often exclude the specific hazards you face daily.
General Liability for Property Damage and Bodily Injury
General liability insurance covers third-party claims when your work damages someone else's property or injures a bystander. For sewer specialists, this means protection when excavation undermines a neighbor's foundation, when a trench collapse injures a pedestrian, or when your equipment damages a client's landscaping beyond the agreed work area.
Standard GL policies for Ohio sewer contractors typically carry limits between $1 million per occurrence and $2 million aggregate. Municipal contracts often require higher limits, sometimes $5 million or more for work in downtown areas or near critical infrastructure. Your policy should specifically include coverage for underground operations, as some carriers exclude this work or charge substantial additional premiums.
Professional Liability and Errors and Omissions
Professional liability, sometimes called errors and omissions coverage, protects you when your expertise fails. If you misdiagnose a sewer problem, recommend an inadequate repair method, or provide inaccurate camera inspection reports, clients can sue for the resulting damages.
Consider a scenario where you clear a blockage but miss root intrusion further down the line. The homeowner experiences a backup three months later, flooding their finished basement. Professional liability covers your defense costs and any settlement, even when you followed standard procedures.
Pollution Liability for Hazardous Waste and Backflows
Standard general liability policies exclude pollution-related claims, creating a dangerous gap for sewer contractors. Pollution liability insurance fills this gap, covering cleanup costs, third-party bodily injury, and property damage from sewage releases, chemical spills, or contaminated soil disturbance.
Ohio's EPA takes sewage releases seriously. A backup that contaminates a
residential well or reaches a waterway triggers mandatory reporting and potential fines. Pollution coverage helps you respond quickly, fund required remediation, and defend against regulatory actions.

Ohio-Specific Regulatory and Legal Requirements
Ohio imposes specific insurance requirements on contractors performing sewer work. Non-compliance can result in license suspension, contract termination, and personal liability for business owners.
Ohio Bureau of Workers' Compensation (BWC) Compliance
Ohio operates a monopolistic workers' compensation system through the Bureau of Workers' Compensation. You cannot purchase workers' comp from private insurers. Every Ohio employer with one or more employees must register with BWC and maintain active coverage.
Sewer line work falls into classification codes with elevated premium rates due to trench hazards, heavy equipment operation, and confined space exposure. Your premium depends on your claims history, payroll, and safety record. BWC offers group rating programs that can reduce premiums by 50% or more for contractors with strong safety records.
Independent contractor relationships require careful documentation. If BWC determines your "subcontractors" are actually employees, you'll face back premiums, penalties, and potential criminal charges for premium fraud.
Surety Bonds for Municipal Licensing and Permits
Most Ohio municipalities require surety bonds before issuing sewer work permits. Columbus requires a $10,000 contractor bond. Cleveland's requirements vary by project scope. Cincinnati mandates bonds for any work in the public right-of-way.
Surety bonds differ from insurance. They guarantee you'll complete work according to code and pay subcontractors and suppliers. If you default, the surety pays claims and then seeks reimbursement from you. Bond amounts for Ohio sewer contractors typically range from $5,000 for basic licensing to $50,000 or more for major municipal projects.
Protecting Physical Assets and Heavy Machinery
Sewer repair equipment represents significant capital investment. A single camera inspection system can cost $30,000. Excavators, trailers, and specialized tools add up quickly.
Inland Marine Insurance for Excavation Equipment
Inland marine insurance covers equipment that moves between job sites. Despite the name, it has nothing to do with boats. This policy protects your excavators, trenchers, pumps, generators, and diagnostic equipment against theft, vandalism, and accidental damage.
Coverage applies whether equipment sits at your yard, travels on a trailer, or operates at a customer's property. Policies can be written on actual cash value or replacement cost basis. Replacement cost coverage costs more but pays to replace damaged equipment with new items rather than depreciated values.
| Coverage Type | What It Covers | Typical Deductible |
|---|---|---|
| Actual Cash Value | Depreciated equipment value | $500-$2,500 |
| Replacement Cost | New equipment of similar type | $1,000-$5,000 |
| Agreed Value | Pre-determined amount | $500-$2,500 |
Commercial Auto Insurance for Specialized Fleet Vehicles
Standard personal auto policies don't cover vehicles used for business purposes. Commercial auto insurance protects your service vans, dump trucks, and equipment trailers. Ohio requires minimum liability limits of $25,000 per person and $50,000 per accident for bodily injury, plus $25,000 for property damage.
These minimums are dangerously low for commercial operations. A serious accident involving your excavator transport could generate claims exceeding $1 million. Most sewer contractors carry at least $500,000 in combined single limit coverage, with $1 million recommended for firms operating larger vehicles.

Mitigating High-Risk Sewer Excavation Hazards
Underground work creates risks that surface contractors never encounter. Your insurance program must address these specific exposures.
Underground Utility Damage and Digging Risks
Striking underground utilities remains the most common and costly hazard for sewer excavation contractors. Ohio law requires calling 811 before digging, but locate marks aren't always accurate. Unmarked private utilities exist throughout older neighborhoods.
Your general liability policy should include coverage for underground utility damage. Some policies exclude this exposure or impose sublimits that cap coverage at $50,000 or $100,000, far below potential damages from hitting a major gas or electrical line.
Request a policy review specifically addressing utility damage coverage. Understand your sublimits, deductibles, and any exclusions for specific utility types. Gas line damage claims average $50,000 to $150,000, while fiber optic cable strikes can exceed $500,000 when business interruption claims pile up.
Completed Operations Coverage for Long-Term Projects
Completed operations coverage protects you after you leave the job site. If a sewer repair fails six months later and floods a basement, this coverage responds. Without it, you're exposed to claims for years after finishing work.
Ohio's statute of limitations for
construction defect claims extends to four years from discovery of the defect, potentially much longer than you might expect. Maintain completed operations coverage continuously, even during slow periods. A coverage gap could leave you exposed for work performed before the lapse.
Customizing Policies for Ohio Plumbing and Drainage Firms
Generic policies waste money on coverage you don't need while leaving gaps in areas that matter. Work with an agent who understands sewer contracting to build a program that fits your actual operations.
Evaluating Deductibles and Coverage Limits
Higher deductibles reduce premiums but increase your out-of-pocket costs when claims occur. A $5,000 deductible might save $2,000 annually compared to a $1,000 deductible. If you file one claim every three years, the higher deductible costs you money.
Coverage limits require similar analysis. Underinsuring saves premium dollars until a major claim exhausts your limits. The difference between $1 million and $2 million in general liability coverage might cost $800 annually but could save your business from a catastrophic loss.
Bundling Options for Small to Mid-Sized Contractors
Business owner policies bundle general liability, property coverage, and business interruption insurance at discounts of 10% to 20% compared to purchasing each separately. For contractors with annual revenue under $5 million, BOPs often provide the most cost-effective coverage structure.
Larger firms may benefit from commercial package policies that allow more customization. These policies let you select specific coverage modules, adjust limits independently, and add endorsements for unusual exposures.
Frequently Asked Questions
How much does insurance cost for Ohio sewer contractors? Annual premiums typically range from $5,000 for small operators to $50,000 or more for established firms. Your specific cost depends on revenue, employee count, equipment values, and claims history.
Do I need pollution liability if I only do residential work? Yes. Sewage releases can contaminate neighboring properties regardless of whether you work residential or commercial. A single backup reaching a neighbor's well creates significant liability.
What happens if my subcontractor causes damage? You're typically liable for subcontractor actions. Require certificates of insurance from all subcontractors and verify coverage is active before they start work.
Can I use personal auto insurance for my work van? No. Personal policies exclude business use. Claims will be denied, and you may face policy cancellation for misrepresentation.
How do I reduce my workers' comp premiums?
Join a BWC group rating program, implement documented safety programs, and maintain a clean claims history. Premium reductions of 30% to 50% are achievable.
Making the Right Choice for Your Business
Protecting your Ohio sewer line repair business requires more than buying the cheapest policy available. You need coverage that matches your specific operations, meets Ohio's regulatory requirements, and provides adequate limits for the claims you might actually face. Start by inventorying your equipment, documenting your typical project scope, and understanding which municipal contracts you want to pursue. Then work with an insurance professional who specializes in construction and excavation contractors. The right coverage costs more than the minimum, but it's far less expensive than defending a lawsuit without adequate protection.

Aaron and Sandra are amazing! I faithfully stayed with my previous insurance for over ten years until I had them review my policies. Wish I would have done it years ago. Saved me quite a bit of money as well as gaining coverage what's not to love? They respond very quickly and professionally. I work in sales as a profession so it's great to see that level of attention and attentiveness provided here. Stop your search and give them a shot you won't regret it. On a side note even though it is something so small I love the fact they send laminated copies of insurance cards anytime you make a change. 10/10
