I cannot say enough good things about Levstein & Stern. I have had them out for three different issues, each one of which I thought was going to be a major crisis, and each one of which they dealt with in the simplest, most economical way. They charge a very reasonable labor rate, they do not mark up the cost of materials, they respond very quickly to messages, and everyone I've dealt with (Ari Levstein once, a guy named David once, and Stephen Stern and Andrew once for a multi-day job), is courteous, straightforward, and totally focused on getting the job done quickly and right. Obviously you never *want* to have plumbing problems, but these guys are so great that I actually look forward to working with them again when, inevitably, some new plumbing crisis arises.
