Who is Vermont Mutual?

Vermont Mutual was chartered in 1828 and is headquartered on State Street in Montpelier. The company describes itself as one of the ten oldest mutual property and casualty insurers in the United States. It is owned by its policyholders rather than stockholders.

Vermont Mutual Insurance Group is the trade name of three companies: Vermont Mutual Insurance Company, Northern Security Insurance Company, Inc. and Granite Security Insurance Company. The group provides coverage throughout New England and upstate New York through more than 600 independent agencies, and publishes personal lines (auto, dwelling fire, homeowners, inland marine and umbrella) and commercial lines (businessowners, inland marine and umbrella).

Why Portsmouth Atlantic quotes Vermont Mutual

Vermont Mutual is the lead carrier we use for Vermont homes and rentals. Outside Vermont, it is one of our core property markets in New Hampshire, Maine, Massachusetts and Connecticut, and one of the carriers we can name for higher-value homes in Massachusetts and Connecticut.
