"Corvus Construction is one in a million! Denis and the crew were responsive and professional at all times. Here are a few examples: 1. The crew showed up for work every day ready to go and prepared with a good attitude. 2. During the day, the crew was considerate of personal property and communicated very well on desires and questions. 3. Before leaving each day they cleaned up the work area as much as possible making certain it was safe for us to use without stepping on something sharp. Also, each day before leaving, the guys asked if we wanted to check their progress and answer any questions we may have had. Denis runs the crew with a tight rein and keeps track of everything about to happen in the expected order. There was never a time when we were uncertain of the progress expected and all questions were answered promptly. Any new issues were resolved without delay. Making this team even more exceptional, Denis went above and beyond to help us figure out another problem we were experiencing outside of the contracted job. We did what he suggested saving us even more stress, time, and money. Besides the carpenters being on point, accurate, and amazing, the tile expert created a work of art we are very proud of and will enjoy for the rest of our lives. We look forward to hiring Corvus Construction again for future projects."
