A family business built on craftsmanship, trust, and construction with integrity.
We are a full-service general contracting firm with 70+ combined years of experience.

KJN Builders is fully licensed in the state of Wisconsin. All pricing is per project and based on the job scope of work, specs, plans, and meeting with staff members to give our clients exactly what they want. Our company is a family business with close ties to our local community.
For over 45 years, Jim has been a major force in the construction industry. He started his career in the early 70's building homes and has been going strong ever since. In the early days of KJN it was just him guiding the way. Today he gets to enjoy watching KJN move forward into the next generation with the help of his boys. In the rare moments he spends away from KJN, Jim loves to golf, officiate high school football, or spend evenings out dining with his wife of over 35 years.
Nick knew at a very young age that he was going to work in construction. Jim bought him a toy hammer at the age of two and he hasn't stopped swinging one since. Growing up he worked summers for the company starting in the 7th grade all through high school. After graduating from Kettle Moraine in 2005, he started working full time for KJN the following week. Nick lives in Mukwonago with his wife Emily, and three children. In his very rare spare time you can usually find him on the golf course.
We do what we say. Jim follows up on every job personally to be sure everything went as planned.
Your job is completed on schedule and on budget, with the highest level of attention to detail.
