ADU PlanningBathroom RemodelingDesign-Build ADU

Our company began in 1994 with a simple idea: provide our community with a trustworthy partner in home improvements. We had seen too many neighbors, friends and family members give their trust, time and money to “fly-by-night” contractors who let them down, performed substandard work or even left town with their hard-earned money. After working in the trades for years Jeff Bartelt saw that, even in the best companies he’d worked for, there was a lack of attention to detail and often the simplest solution was overlooked in favor of sales. He saw a need in the local market for someone who would put the customer’s best interest at the heart of every decision, and so JJB Home Improvements was founded. That’s still our philosophy today. We know you love your home. Something drew you to it and even if it was only a choice of convenience, your home is special to you. We want to help you make it the best it’s ever been, so you can enjoy it now, save money on energy and future repairs, and retain the highest possible resale value for when the time comes. We have made a long-term commitment to the Greater Milwaukee community and we stand behind our work. We look forward to serving you!
