Humble Beginnings: A True Mom-and-Pop Shop

Glenn and Lois Long started Glenn C. Long Plumbing & Heating in 1949 out of their home in Northville, Michigan. Glenn would make the service calls and Lois answered the phone and took care of the company books.

The business began to grow and in 1954 they constructed an office, showroom and warehouse on Seven Mile Road, east of Northville Road, which allowed them to display household appliances and plumbing fixtures. In addition to servicing residential accounts, they began providing plumbing service to businesses. Additional employees were hired to service their growing number of customers.

Moving Downtown & Expanded Capabilities

In 1964, Glenn Long acquired property in downtown Northville and a new building was constructed on Dunlap Street. The larger showroom featured plumbing fixtures and stocked parts for plumbing repairs.

In the late 1960s, Long Mechanical became the parent company of Long Plumbing with an expansion of services to our commercial customers.

In 1970, a portion of the downtown showroom was dedicated to bath accessories, which laid the groundwork for today's Long Kitchen & Bath Design Gallery.

Continued business growth led to the construction (in 1974) of the current office, showroom and retail store, then called our "Fancy Bath Boutique," at the north end of Main Street in downtown Northville.

Out-of-State Expansion

Further expansion occurred in 1982 with the opening of JR Long, Inc. in Tampa, Florida. Specializing in commercial plumbing and pipefitting, projects included work at Tampa International Airport, the Tampa Convention Center, and numerous schools and medical facilities. In 2004, after twenty-two years of operation, JR Long, Inc. was sold to three employees.

The Long Companies Today: Honoring Our Reputation

From the little mom-and-pop operation that began more than sixty-five years ago, The Long Companies has grown into a multi-million dollar private corporation built on a solid reputation of service and integrity.

While we continue to offer timely, reliable service to our residential customers throughout Metro Detroit, our portfolio of commercial mechanical and HVAC projects continues to expand.

Professional Affiliations

The Long Companies, along with many of our employees, have been active members in numerous industry and local organizations since we began in 1949, often taking on leadership roles. We strongly believe that in order for us to be the best, we need to continually improve our knowledge and skills. We also believe it is crucial to stay current with new regulations, techniques, technologies, and the latest products so that our customers receive the best and most comprehensive sales and service available.

Featured in Plumbing & Mechanical Magazine, November 2009, Up On Main Street

"Long Mechanical has experienced tough times before now. The Detroit metropolitan area, where the plumbing and mechanical contractor works, became mired in the current economic downturn well ahead of the rest of the country. “Michigan has been in a rut for seven years,” Owner Jim Long says. The company, however, has reason to celebrate this year. Long Mechanical commemorated its 60th anniversary June 5 with an open house at its Long Bath Design Gallery showroom for its customers and neighbors in downtown Northville, Mich.… Read More
