J.F. Brennan Company, Inc.
We are not your typical construction company.
At Brennan, we specialize in dam construction and repairs on navigational, hydroelectric, diversion, storage, detention, and earthen structures of all sizes. We work on every part of the dam, both above and below the waterline. Brennan crews have the experience and equipment necessary to work in a variety of conditions, including confined spaces, elevated work stations, underwater construction, and more.
