Who We Are

In 1980 John and Elaine Knight founded Knight’s Plumbing. By always treating customers and employees fairly the company has grown from its original staff of only one to now nearly 150. John and Elaine then purchased French Mechanical in 1990 from Addie S. French, who had been in business for over 40 years and specialized in heating, air conditioning and sheet metal fabrication. In 1994, we combined both Knight’s and French Mechanical under one roof and built a 26,000 sq. ft. shop at our present location: 4250 Leitchfield Rd.

Since the first day we opened our doors Knight’s Mechanical has never stopped growing and moving forward. We can attribute our success not only to customer loyalty but also to the skills and abilities of the trained craftsmen that we employ. It goes without saying that here at Knight’s Mechanical we have the experience and expertise to service all of your plumbing, heating and air conditioning needs.
