Chung is terrific. He always lets me know when he'll be arriving and he does what he says he's going to do! He knows his stuff, too. This is the second time we've had Chung fix plumbing for us. The first time was a much bigger job involving cutting through very thick marble tile, clearing out faulty pipes, cleaning out black mold (!!), and finding replacement fixtures to match what remained of the old fixture. NOT EASY! But he got it done well and professionally. The recent job he did for us was getting the decade-old+ Toto operating properly again (it was leaking, not flushing well, etc.). He did a great job again. I would recommend (and I have) Chung anytime!
