JJB Home Improvements Oconomowoc

We Handle the Mess. You Get Your Dream Home. JJB Home Improvements began in 1994 with a simple idea: to provide Wisconsin communities with a trustworthy partner in home improvements. Our founder, Jeff Bartelt, saw a need in the local market for putting homeowners’ best interests at the heart of every decision. That’s still our philosophy today. We believe remodeling your home should be as rewarding as living in it. As Oconomowoc's premier home addition and design-build partner, we’ve spent over 30 years learning to take the chaos out of home improvement. We manage every detail with care, clarity, and respect for your home and lifestyle. From design to permits to final walkthrough, you’ll have one trusted team dedicated to creating spaces that improve the way you live, work, and relax.
