Welcome to Johnson Industrial

Plumbing • Piping • Hydronics 

Established in 1988

Johnson Plumbing Industrial was established in 1988, Eugene B. Gantney, Jr. and Steven Davis pursued their passion to provide the Central Valley with professional and quality plumbing and piping services.


Six years ago we worked along side Johnson Industrial rehabilitating historic cabins.  Soon we began to understand they have the same philosophy in their trade as we have which has earned them our greatest respect.  After working alongside them for four years, I hired them to provide the plumbing for the Mariposa Grove South Entrance Station and an additional comfort station in Yosemite National Park. 

The quality of Johnson Industrial’s workmanship and overall concern for each project is unparalleled.  They are careful and methodical in their work, and it shows.  It is my pleasure to work with them.  I look forward to many more projects with them.

Johnson Industrial, Inc. was our plumbing subcontractor for the National Environmental Science Center project located in Yosemite National Park. The project consisted of a Dining Hall, Maintenance Building, Bathhouse Building and two cabins. Johnson Industrial did an outstanding job and we were especially impressed with their quality of workmanship, ability to maintain the project schedule and overall helpfulness of their field and office staff in resolving any problems. I would not hesitate to use Johnson Industrial, Inc. on any of our upcoming projects or to recommend them to others.
