Construction With Integrity
In 1976, Jim Lewein opened up shop for himself where he honed his skills and grew into a master carpenter and general contractor. In 1991 he renamed the company KJN, after his wife and two children. Since then it has grown into a leading construction company for all of Southeastern Wisconsin, and is now being lead into the next generation with the help of his two sons, Nick and Jake.
KJN Builders are fully licensed in the state of Wisconsin where we do all of our work. All pricing is per project and based on job scope of work, specs, plans, and meeting with staff members to give our clients what they want. Our company is a family business with close ties to our local community.
