Approximately 16 miles north of downtown Chicago, Winnetka is known for its many recreational activities, its excellent schools, and the filming location for Home Alone. It is also considered to be one of the wealthiest communities in the U.S. based on average household income. Over time, LaMantia has helped many homeowners and businesses with their renovation projects. You can see our work all over Winnetka with new-looking homes, added rooms, updated kitchens, and bathrooms. Thinking of changing something? We have lots of ideas.
