We Are Always Looking Forward

Our simple goal for the future is to just keep doing a great job for you.

Every day at The Andover Companies, we work with a strong sense of accountability to each of our policyholders and do our very best to meet their ever-changing individual property insurance requirements.

We understand that as a property or business owner, you require a broad range of insurance products to protect all your diverse assets and investments. From a private home or condo you own to an apartment complex or small mixed-use property you’ve invested in, The Andover Companies is built to effectively meet your wide-ranging insurance needs.

Our company is made up of three subsidiaries—Merrimack Mutual, Cambridge Mutual, and Bay State Insurance—which means we can provide our policyholders and their independent insurance agents with access to numerous insurance solutions for almost every type of property and budget.

However, there’s much more you can count on from us.

  • We commit to providing you with outstanding coverage solutions at consistent and competitive rates.
  • We are dedicated to maintaining a company that is financially stable and dependable, and have consistently been rated "A" (Excellent) or higher by A.M. Best, an independent insurance rating firm.
  • We promise to pursue innovative ways to make the insurance process easier for you, including our modern and streamlined online technology that allows you to view and print policy documents, make payments, and file and review claims.
  • We believe in being a responsible corporate citizen and will continue to engage in numerous green initiatives, such as installing a smart roof to reduce our energy load year-round and building a solar field to generate supplemental power for our headquarters.

As an Andover Companies policyholder, you truly get the best of both worlds. While we strive to be a company that is continually evolving and modernizing, our team will also always be here to offer you old-fashioned, personal, hands-on help and support.
