W. L. Gary boasts a rich history that has stood the test of time over the past 125 years. No matter what challenges lay ahead, our experience and longevity position us well to continue bringing lasting solutions to our clients.
W. L. Gary Company joins the war effort with a contract from the Department of the Navy. The sheet metal shop builds scale model ships for the David Taylor Model Basin. After the Navy tested the ships they send them back to Gary Company for repairs.
The company passes to Brooke Greer, Randy Greer, and Mike Dent. Brooke serves as the president of W. L. Gary Company, while Randy serves as the Executive Vice President overseeing the service department, and Mike serves as the Executive Vice President running the construction department.
Bill Gary decides to concentrate on plumbing and heating, closing the sheet metal and roofing part of the business. As a result, W. L. Gary Company, Inc. came to be known to our customers as Gary the Plumber.
Gary Company receives our first hospital job at Washington Hospital Center.
Gary the Plumber hires our first full time steamfitter journeyman, Joseph (Joe) Dent, who helps provide complete mechanical solutions with the addition of air conditioning as a new service to our clients.
During the 1968 riots in D.C. the main Gary office on 3111 14th Street NW is burned down. Unable to salvage the building or the records inside, W. L. Gary Company finds a home with Tuckman-Barbee Construction. After only a few months, we set up shop at 225 Vine Street NW.
Walker Littlebury Gary, a young Washingtonian plumber, begins a plumbing, heating, and roofing mechanical business – W. L. Gary & Company.
Two of Buddy’s sons are hired. Brooke C. Greer as a steamfitter and W. Randall (Randy) Greer as a plumber. With their addition, the 4th generation is on board.
The company office moves to several different locations on 14th St NW before settling at 3111 14th St, a location purchased by Walker and his wife Roy. 
Bill Gary passes away after a battle with cancer. His widow, Anne Gary, becomes president for a few years before passing the role onto her nephew, Buddy Greer.
Walker incorporates his business as W. L. Gary Company, Inc. Both of his sons as well as a couple business partners, including Phillip Moorehead, his son-in-law, receive shares in the company. 
Gary the Plumber returns to its legal name, W. L. Gary Company, Inc., with total mechanical solutions now being our main focus.
The company is hit not only by the Depression sweeping the nation but also by several deaths including the beloved founder Walker Littlebury Gary and then his eldest son William Spencer Gary a few months later.
Joe Dent becomes the president and Buddy Greer becomes the Chairman of the Board.
Roy Spencer Gary, Walker’s wife, becomes the president of the company. Her youngest son William (Bill) Gary, leaves school to help run the business.
After 50 years with W. L. Gary Company, Buddy Greer passes away. Joe Dent, the only non-family member to hold the office of president, runs W. L. Gary Company for the next 7 years until his retirement.
William C. (Buddy) Greer, Bill’s nephew, is hired.
