I hired Black Diamond to repair the former icebox in my basement. My home, which is a 1920s rowhome, is a flip. The flippers simply drywalled the walls and tried to play it off like a bonus room. Sure enough, the bonus room is flop - moist, chilly, and utterly different than the rest of the basement. I hired Black Diamond to make the entire basement feel like a more cohesive space and they did exactly that. BD was the fourth contractor that I contracted - I was tired of all the back and forth. BD was straight-forward, fair, and fast. I wanted the work done before Thanksgiving - Not a problem. I wanted an additional area framed out - Not a problem. I wanted a transparent experience - Thankfully, not a problem. The job is done, more than a week before thanksgiving, and my basement looks like one well-thought out space. I would definitely recommend them.
