Wolf&Grayson EditorialFor Leon Leinbach, building companies is about something larger. From his beginnings on a Kentucky farm to founding multiple companies across construction, manufacturing, and service industries, Leinbach has demonstrated that growth comes from a mix of grit, innovation, and deeply held values. His ventures, including Keystone Construction and Blue Jay Garage Doors, are proof that a small operation can scale into a regional powerhouse without losing sight of purpose.
“Entrepreneurship is about creating lasting impact—building businesses that not only thrive financially but also uplift communities and inspire future generations,” he explains.
From Hammer to High-Growth
Leinbach entered construction at the age of 19, armed with little more than determination and a willingness to learn. He founded Keystone Construction in 2005 and steadily grew it into a multi-million-dollar enterprise, completing over 3,000 post-frame buildings. “Growing up on a farm, I learned about hard work, learned what it takes on consistency, on growing companies,” he says.
Today, Keystone Construction serves residential, agricultural, and commercial projects across several states, and its growth helped pave the way for Blue Jay Garage Doors, which has built a loyal consumer base of homeowners seeking safe, reliable, and innovative garage door solutions. This natural progression came as Keystone expanded and Leinbach recognized an unmet need in garage door service. “We were doing a lot of garage doors within that company. But we needed good service technicians and garage door guys. And that led us to building our own company, Blue Jay Garage Doors.”
Prioritizing Safety and Longevity
For Leinbach, growth is about creating value for customers. Nowhere is this more evident than in his garage door business, where he emphasizes both innovation and everyday care. “One of the most common challenges for homeowners in Kentucky and Tennessee is managing their garage door,” Leinbach says. “It is the largest moving wall of the home, and when it is not functioning properly it creates concerns around convenience, safety, and security.”
What keeps customers loyal is the time his team spends educating them, often spending time showing homeowners simple steps to prolong the life of their garage doors, such as greasing rollers, checking cables, and using proper lubricants. “The spring above the garage door is where it is mounted. Applying lubricant regularly helps prevent it from drying or cracking, which extends both the longevity and the safety of the door,” he says, adding a bonus tip: “washing the seals to keep everything rolling smoothly.”
Professional maintenance, however, remains essential. “What we typically do when we come out, when somebody has a problem with their door or they just want us to come out and just make sure their door is good — we have a 29-point inspection safety list that we go through. We inspect the door from top to bottom, making sure everything’s good.”
Scaling Through Innovation
Leinbach’s ability to grow operations rests not only on craftsmanship but also on foresight. He has a clear view of where technology is taking industries and how to integrate those shifts into practical services.
One example is smart delivery integration, where garage doors sync with Amazon or UPS deliveries. “When an Amazon truck delivery comes or UPS delivery comes, they can open up the garage door and it’s got a camera there. They slide the package underneath and close it again for you, and you can watch it on real time on your computer or your smartphone,” Leinbach explains.
He also sees the role of artificial intelligence expanding. Blue Jay Garage Doors already uses voice AI to handle follow-ups and fill in when staff are off-duty. “I don’t see that in the near future AI will replace a lot of the human elements because a lot of people still love talking to humans, and we care about that,” he says. Instead, he views AI as a support system, not a replacement.
Building Beyond Business
From a single construction outfit to a suite of businesses across Tennessee and beyond, his story demonstrates how vision and discipline can transform small beginnings into sustainable growth.
At the core of Leinbach’s leadership success is a commitment to people. “Every project I take on is an opportunity to create something meaningful and lasting, whether for my clients, my team, or the community,” he says.
