We hired Steven Cho to fix a small plumbing repair but after a careful inspection, we agreed that many of the pipes in our house were on the verge of breaking. We had him re-do all the pipes throughout our house. He did it in good time and used up-to-date flexible pipes so as to avoid too many holes in the walls. He has come back and repaired a sink install that the company who did our granite countertops messed up with. I highly recommend.
