With oil and gas discoveries in the region, Adam’s son William sold the tannery business and formed Kinley Oil Company in 1911. This company produced oil and gas in Western New York and Northwestern Pennsylvania for the next 80 years.

Over time, Kinley Oil Company took a natural turn to industrial construction and Kinley Corporation was formed in 1964 in Western New York state to serve the commercial construction business. The early 1980s was a time of expansive growth for Kinley's industrial construction business as it expanded to Nebraska by acquiring and managing fuel terminals. In 1988, the growth of the construction business led to the formal establishment of Kinley Construction.

Formally known as Kinley Construction Group (KCG), KCG became a nationally recognized and respected general contractor serving the industrial and mechanical fueling industries in the aviation, railroad, energy, and government industries. Kinley Corporation in Western New York continued to build and grow its commercial construction business.

In 2022, Kinley Construction formed Kinley Advanced Technical Services to offer nationwide service and maintenance solutions to the rotating equipment industry, including steam turbines, reciprocating and integral engines and related compressors. The company's sixth generation continues a legacy-driven, long-term approach to growth, while bringing with them the foundation of relationships, values, people, and experience that began at Kinley and Sons more than 125 years ago.
