512 refitted our commercial offices at our business and added a good-sized addition. We had a lot of special needs because of the type of business we own. 512 was fantastic and spent the time to completely understand our needs upfront. They gave us a price quickly and efficiently. We were out of state for much of the construction, but we able to communicate through her phone app. We were provided a schedule and they were always on schedule or early. They provided regular updates, including pictures of the progress. We were thrilled to return to a project in the final stages of completion. It was extremely important to us to have our project done on time. Our prior experiences with contractors have ended unpleasantly with our business temporarily shut down due to delays.  This crew is the opposite. We recommend them without reservation. You will be glad you chose them.
