I had a plumber, Mark, for the service. He was very professional and knowledgeable who tried best to solve an issue I (still) have that was unknown. Water was not draining in the shower that was newly remodeled, which used to be a bathtub drain, but next to that drain works fine. I tried all possible way to figure it out, even with a contractor. Long story short, Mark gave me a better picture on what it is/possible is. The result is still not fixed, but he provided answer to my curiosity so I get to move on to find an alternative solution (temporary). Mark and his assistant worked well and explained the process clearly. Most importantly, their professionalism priced very reasonable, honest, and had a good quality of work. I highly recommend him and his team.
