"The work that Dave’s company performed was great with the exception of the living room, that ended up being mid-matched. Dave’s crew let me know that because of this they would paint the whole living room. They asked me to call and set up an appointment and I did. The day came and nobody showed up. I called Denise and she stated her crew called in sick and they were leaving town the next day. She would have Dave call me. He didn’t, so I txt him the following week and he called and said it would be more money, which it shouldn’t as I was previously told they mid-matched it so they would make it right. He was supposed to call later in the week and never did. I find though everyone was nice, the professionalism was lacking. I would not use again because of this."
