What General Liability Covers for Plumbers in Wisconsin

General Liability Insurance for plumbers in Wisconsin covers third-party bodily injury, property damage, and advertising injury claims. This means that if a client or visitor is injured on your job site, or if you accidentally damage their property, General Liability will help pay for the resulting damages. For example, if you're working on a pipe in a Milwaukee home and accidentally flood the basement, General Liability will cover the cost of repairs. On the other hand, General Liability does not cover damage to your own tools or equipment, which would be covered under a separate policy like Tools & Equipment Insurance. Additionally, General Liability does not cover employee injuries, which would be covered under Workers' Compensation. You need to understand what General Liability covers and what it doesn't to ensure you have the right protection for your business.

Do Plumbers in Wisconsin Need General Liability?

In Wisconsin, most general contractors, commercial property managers, and municipal clients require plumbers to carry at least $1 million in General Liability coverage before they are allowed on a job site. This is because General Liability helps protect these clients from potential lawsuits and damages. Even if you're not required to have General Liability by law or contract, it's still a good idea to have it to protect your business from unexpected claims. Without General Liability, you risk being held personally responsible for damages, which could lead to financial ruin. For instance, if you're working on a job site in Madison and accidentally damage a client's property, you could be held liable for the damages. General Liability would help cover these costs, protecting your business and personal assets. You should consider the potential risks and consequences of not having General Liability when deciding whether to purchase it.

The client sued Green Bay Plumbing for the cost of repairs, and General Liability Insurance kicked in to cover the claim. The insurance company paid $10,000 to settle the lawsuit, and Green Bay Plumbing avoided a costly payout. If you're a plumber in Wisconsin, you need to be prepared for unexpected claims like this one, and General Liability can help protect your business. The claim was handled efficiently, and Green Bay Plumbing was able to continue operating without significant financial disruption. The business owner was relieved that the General Liability Insurance covered the damages, and they were able to focus on their work without worrying about the financial consequences of the accident.

Frequently asked questions

Will my General Liability premium jump after one claim?

Yes, it might. After a claim, your premium could increase, depending on the severity of the claim and your claims history. However, some insurance companies offer claims-free discounts or forgiveness programs, which can help mitigate the impact of a claim on your premium. You should review your policy and discuss your options with your insurance broker to understand how a claim might affect your premium.

Can I get a COI same-day for a client?

Yes, you can. Many insurance companies offer same-day certification of insurance (COI) for clients, which can help you meet contract requirements quickly. However, this may depend on the complexity of the request and the availability of the insurance company's staff. You should contact your insurance broker or company to see if they offer same-day COI services and what the requirements are.

Does a sole proprietor need General Liability?

Yes, they do. As a sole proprietor, you're personally responsible for any business-related liabilities, which can put your personal assets at risk. General Liability Insurance can help protect your business and personal assets from unexpected claims, even if you don't have employees. You should consider purchasing General Liability Insurance to ensure you have the right protection for your business.

What's not covered by General Liability?

General Liability does not cover damage to your own tools or equipment, which would be covered under a separate policy like Tools & Equipment Insurance. Additionally, General Liability does not cover employee injuries, which would be covered under Workers' Compensation. You should review your policy and discuss your options with your insurance broker to understand what's covered and what's not.

Can I cancel my General Liability policy at any time?

Yes, you can. However, canceling your policy might result in a penalty or a loss of coverage, depending on the terms of your policy. You should review your policy and discuss your options with your insurance broker to understand the implications of canceling your policy. It's generally recommended to maintain continuous coverage to ensure you have the right protection for your business.
