I highly recommend top tier plumbing. We called five plumbers before top tier and all were problematic (either flaky, incompetent, or exorbitantly expensive). All we needed was a plumber to hook up our new kitchen sink, but because of our plumber woes we've been living without a sink for 2 weeks (washing dishes in the bathroom, eating takeout, etc. ). Yesterday we called Top Tier plumbing and the same day Nathan showed up, was very knowledgeable, and fixed everything perfectly for a reasonable price. He was also super cool, and we are very happy because now we have a great plumber for the future.
