About Us

In 1921, Mr. James B. Donaghey established his private plumbing repair and contracting business in Mobile, Alabama, and it remained a plumbing company through the 1920s. In the 1930s a heating division was formed, and the small firm — James B. Donaghey Plumbing Company — expanded quickly into the commercial and industrial markets. In the 1940s the business became a leader in south Alabama in the installation of central air-conditioning systems.

In 1950, James Donaghey’s son-in-law, Maynard “Sandy” Sanders, joined the company, and James’ son, Bradley, soon followed in 1953. With increasing business demands and a record of exceeding customer expectations, the three reorganized the company in 1958: James B. Donaghey, Inc. Mechanical Contractors was formed, adding a sheet metal shop to provide complete mechanical installations for commercial and industrial clients. Today, the original Donaghey commitment to quality guides the company as it continues to grow on the core values of ingenuity and integrity.

Bradley Donaghey is still with the company, serving as Chairman of the Board and as a mentor and inspiration to the third generation — Judson Sanders, Bob Clapper and Joe Vallée — and the fourth generation of John King and Zach Vallée as they position the company for the future.

Built on history and tradition, James B. Donaghey, Inc. remains family-owned and operated to this day as an S Corporation. Our mechanical contracting capabilities are the result of more than 100 years of solid engineering methodology, providing logical, cost-effective building system solutions in a safe, professional manner that has grown the company to four offices.
