In 1971, Ed Pruitt Sr. founded E.L. Pruitt Co. The business started as a successful sheet metal and roofing company for residential and commercial businesses. In 1980, Ed Sr. sold his business to sons, John and Ed, Jr. for a 50/50 split. Ed. Sr. passed away in 1983 and his sons expanded services and looked for growth opportunities.

Growth and Expansion
E.L. Pruitt Co. expanded its services in the mid 1980s. In 1984, the company added the piping trade followed by plumbing services in 1989. Both trades became crucial to the business. A piping fabrication shop was added in 1999, making production and quality control of these services much more efficient for the customer.

In 1990, the sheet metal shop began to use its first coil line. This allowed for increased productivity due to automation of the system. Our craft masters now had a path to increased production of large-capacity jobs. Demand for large-capacity jobs grew and technology continued to evolve. In 2009, a newly updated coil line was added, along with a plasma table and a water jet line. Rapid productivity exploded for large commercial, industrial and institutional jobs. Reduction of scrap due to frugal material utilization saved customers and the company material, time and money. Efficiency was now a key focus of E.L. Pruitt, Co.

In 1997, John bought Ed Jr.’s half of the business. Under his leadership, the business moved its focus away from residential and strictly toward commercial and industrial jobs in Illinois. The company continued to grow, and jobs poured in throughout central and southern Illinois. In 2011, a Decatur location was added to meet demand.

E.L. Pruitt Co. has weathered memorable business hardships along with many other companies throughout our country. Sky-rocketing interest rates in the 1970s coupled with great inflation led to a recession. After overcoming the market roller coaster, three more recessions followed in 1987, 1991 and 2001. In 1991, a technology bubble required businesses to spend money to grow and try to recover income that had bounced during the inflation and recessions. In 2013, the Illinois state budget crisis began making it difficult for institutions to fund improvements for their facilities. Businesses were left with completed jobs that were now unpaid.

The past fifty years, technology has continuously evolved, making production more efficient. In 1987, plasma cutting tables were developed. Next came the coil line in the 1990s. Production in sheet metal shops boomed. In 1999-2000, computer-aided drafting came into play, making designs precise and resourceful for our company, contractors and customers.


The company's service division has experienced rapid growth with highly skilled technicians who handle 24/7 emergency calls for HVAC and plumbing issues as well as regularly scheduled maintenance for customers. Our HVAC factory-trained technicians service and provide routine maintenance programs on a variety of equipment. Our plumbing team can clear most obstructions with our equipment and our field personnel have 24/7/365 access to any additional equipment required for emergency after hours service.
