Recent, I hired him to put a new bathroom, and long story short, I fired him after he messed completely. I wonder how he got a license. He showed poor quality work and has zero productivity. He never keeps promises or timeline. I attach some pictures here. I which you can see this. If you know anything about plumbing, you will see what he has done to me.
