About Us

6/1/1979 as JK Enterprise

"The Green Machine"

On 10/17/1989, we changed our name to J.K. Mechanical, Inc and filed as a corporation in Pennsylvania.

In 1989, we changed from JK Enterprise to JK Mechanical but kept the same brown and yellow colors in our logo.

In 2006, we kept the same logo but updated our colors form brown and yellow to blue and orange.

Our original office and warehouse was located at 3100 Willow Street Pike South, Willow Street, PA 17584.  In May 2006, we moved to a new office and warehouse building at 202 W Kendig Rd, Willow Street, PA 17584.

We held our first Community Work Day in 2010.  Location was at the Lydia Center in Wrightsville, PA (which was part of Water Street Mission)

In 2012, we redesigned our logo to our current one.  We added JK Electrical and JK Plumbing logos after 2012, but our base logo design in horizontal and vertical format has remained the same since 2012.

In September 2012, we started our electrical department (registered JK Electrical as DBA in state of Pennsylvania).

We’ve been a partner with Hempfield School District in their Annual Food Drive since 2013.

Jim Leaman and Ken Leaman founded the company and were partners until January 1990, when their brother, Ron Leaman, joined them as an owner of the company.  In March 2001, Jim Leaman and Ron Leaman left JK Mechanical, and Ken Leaman became the sole owner. Chris Leaman joined JK Mechanical in May 2004 and became an owner with Ken Leaman in January 2011.  In January 2016, Chris Leaman became the sole owner of JK Mechanical.

In January 2017, we started our plumbing department.
