Our family engaged Y Squared to completely redo a floor in our house to reconfigure the floor to add a hallway and bathroom. It was going to be a complex project requiring lots of coordination between plumbers, electricians, HVAC, drywallers, painters, etc. Somehow Y Squared pulled it off, even when unexpected obstacles would invariably arise as, such as improper prior wiring, support beams that could not be cut, or air ducts that had to be added. It took longer than we had hoped, but it was because Y Squared alerted us to the many issues that had existed in our 100+ year old house. I really appreciate how flexible they were with working around my family's schedule and how upfront they were...
