What General Liability Covers for Plumbers in Delaware

General Liability Insurance for plumbers in Delaware pays for third-party bodily injury, property damage, and advertising injury claims. For example, if a plumber accidentally damages a client's property while working on a pipe, General Liability would cover the cost of repairs. It also covers slip-and-fall accidents or other bodily injuries that occur on the job site. However, General Liability does not cover damage to the plumber's own tools or equipment, which would be covered under a separate Tools & Equipment policy. Nor does it cover workers' compensation claims, which are handled by a separate Workers' Compensation policy.

Do Plumbers in Delaware Need General Liability?

While General Liability Insurance is not legally required for plumbers in Delaware, it is often contractually required by clients, landlords, or contractors. 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. Many also require the client to be listed as an additional insured on the certificate. Without General Liability, a plumber may be unable to work with these clients, which could significantly impact their business. Furthermore, in the event of a claim, a plumber without General Liability could be personally liable for damages, which could lead to financial ruin.

A Real General Liability Claim a Plumber Could Face

It was a routine job until a plumber in Wilmington accidentally damaged a client's expensive flooring while working on a pipe. The client sued the plumber for $10,000 in damages. Fortunately, the plumber had General Liability Insurance, which covered the cost of the claim. The insurer paid $10,000 to settle the claim, and the plumber avoided a significant financial loss. If the plumber had not had General Liability, they would have been personally liable for the damages, which could have put their business at risk.

What General Liability Costs for Plumbers in Delaware

The cost of General Liability Insurance for plumbers in Delaware varies, but typical premiums range from $40-$110 per month. Factors that affect the cost of General Liability include revenue, payroll, coverage limits, deductible, and claims history. For example, a plumber with a high revenue and large payroll may pay more for General Liability than a smaller operation. Additionally, the coastal and river flooding risk in Delaware, as well as the state's elevated liability litigation rates, may increase the cost of General Liability. However, by shopping around and comparing quotes, plumbers can find a policy that fits their budget and provides adequate protection.

How to Get General Liability in Delaware

To get General Liability Insurance in Delaware, plumbers should gather information about their business, including revenue, payroll, and coverage needs. They should also research different insurance providers and compare quotes to find the best policy for their budget. In cities like Dover and Middletown, plumbers can work with local insurance agents to find a policy that meets their needs. By bundling General Liability with other core policies, such as Workers' Compensation and Commercial Auto, plumbers may be able to lower their total premium.

Frequently asked questions

Will my General Liability premium jump after one claim?

Yes. A claim can increase your premium. The amount of the increase depends on the severity of the claim and your claims history. However, having General Liability Insurance can still protect your business from financial ruin in the event of a claim.

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

Yes. Many insurance providers offer same-day COIs. You can work with an insurance agent to get a COI quickly, often within a few hours. This can help you meet client requirements and start working on a project without delay. Be sure to ask your insurance provider about their COI process and timing to ensure you can get the documentation you need when you need it.

Does a sole proprietor need General Liability?

Yes. Even sole proprietors need General Liability Insurance. As a sole proprietor, you are personally liable for business-related claims, which can put your personal assets at risk. General Liability Insurance can protect your business and personal assets from third-party claims, even if you don't have employees.

What's not covered by General Liability?

General Liability does not cover damage to your own tools or equipment, workers' compensation claims, or commercial auto accidents. You need separate policies to cover these risks. For example, Tools & Equipment insurance can cover damage to your plumbing equipment, while Workers' Compensation insurance can cover employee injuries. Commercial Auto insurance can cover accidents involving your business vehicles. Understanding what's not covered by General Liability can help you ensure you have comprehensive coverage for your business.

Can I cancel my General Liability policy at any time?

Yes. You can typically cancel your General Liability policy at any time, but you may face penalties or fees for early cancellation. You should also consider the impact of cancelling your policy on your business, as you may be leaving yourself exposed to third-party claims. Work with an insurance agent to determine the best course of action for your business.

Do I need to list my client as an additional insured on my General Liability policy?

Yes. Many clients require you to list them as an additional insured on your General Liability policy. This provides them with protection in the event of a claim related to your work. You should review your client contracts and requirements to determine if you need to add them as an additional insured. Your insurance provider can help you understand the process and costs associated with adding an additional insured to your policy.

How do I get a General Liability policy with a high coverage limit?

You can work with an insurance agent to find a General Liability policy with a high coverage limit. They can help you shop around and compare quotes from different insurance providers to find a policy that meets your needs. Be prepared to provide detailed information about your business, including revenue, payroll, and coverage needs, to help the agent determine the best policy for you. High coverage limits may be more expensive, but they can provide greater protection for your business in the event of a claim.
