It is hard to find a contractor who takes soundproofing in a residence seriously, or who can really offer much of substance. But Mike Ibarra from Soundproof Chicago has thoroughly figured out the art and science of soundproofing, and has matched it with top-shelf customer service. His predictions to me were very accurate: after soundproofing, we experienced a 50% reduction of footfall noise, and a close to 100% reduction of airborne noise (TV, music, conversation) from a unit above us. The project was messy and involved (also things that Mike had predicted) but he and his team had taken a lot of time to prep the house beforehand, and the place ended up looking better than before he had started. And it is certainly much quieter! A few things didn't turn out as I had hoped, and Mike was right there to resolve everything. He went above and beyond to make sure that every detail was the way I wanted it. I give him the highest possible recommendation.
