What Professional Liability (E&O) Covers for General Contractors in Maryland

Professional Liability (E&O) insurance covers claims of negligence, mistakes, or failure to deliver professional services as promised. This includes financial loss claims, such as a client alleging that your work was late, wrong, or failed to deliver what was promised. It does not cover physical damage or workers' compensation claims, which are covered by other policies. For example, if you are working on a construction project in Gaithersburg and a client alleges that your work was defective, Professional Liability (E&O) insurance would cover the financial loss claim. However, if a worker is injured on the job, workers' compensation insurance would cover the claim. You need to understand what this coverage does and does not cover to ensure you have the right protection for your business. In Maryland, general contractors face a high-risk environment due to coastal flooding and storm surges, which can increase the risk of financial loss claims. Professional Liability (E&O) insurance can help mitigate this risk and protect your business from financial loss.

Do General Contractors in Maryland Need Professional Liability (E&O)?

While Professional Liability (E&O) insurance is not legally required in Maryland, it is often contractually required or strongly recommended by commercial clients. Many clients in Baltimore, Frederick, and Rockville require general contractors to carry at least $1 million in general liability and workers' compensation insurance, and may also require Professional Liability (E&O) insurance. Without this coverage, you risk financial loss and damage to your reputation. If a client alleges that your work was negligent or defective, you could be liable for financial losses, even if you have done nothing wrong. Professional Liability (E&O) insurance can help protect you from these types of claims and ensure that you can continue to operate your business with confidence. In addition, having this coverage can give you a competitive edge when bidding on contracts, as it demonstrates your commitment to quality and professionalism. You should carefully review your contracts and client requirements to determine if Professional Liability (E&O) insurance is required or recommended for your business.

A Real Professional Liability (E&O) Claim a General Contractor Could Face

A general contractor in Baltimore was working on a construction project when a client alleged that the work was defective and caused financial losses. The client claimed that the contractor had failed to deliver the promised results and was seeking damages of $100,000. The contractor had Professional Liability (E&O) insurance, which covered the financial loss claim. The insurance company paid $80,000 to settle the claim, and the contractor was able to avoid a costly lawsuit. Without this coverage, the contractor could have been liable for the full amount of the claim, which could have put their business at risk. Professional Liability (E&O) insurance can help mitigate this risk and provide peace of mind for general contractors in Maryland. The claim was handled efficiently and effectively, and the contractor was able to move forward with their business without significant disruption.

Frequently asked questions

Will my Professional Liability (E&O) premium jump after one claim?

Yes. Your premium may increase after a claim. However, the amount of the increase will depend on the specifics of the claim and your overall claims history. If you have a good claims history and the claim is minor, the increase may be minimal. But if you have a history of frequent or severe claims, your premium may increase significantly. You should review your policy and discuss your options with your insurance broker to understand how claims can impact your premium.

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

Yes. Many insurance companies can provide a certificate of insurance (COI) same-day, but it depends on the complexity of the request and the insurance company's processes. You should check with your insurance broker or company to see if they can provide a same-day COI. Some insurance companies may require additional information or documentation, which can delay the process.

Does a sole proprietor need Professional Liability (E&O)?

What's not covered by Professional Liability (E&O)?

Can I cancel my Professional Liability (E&O) policy at any time?
