Gordon has been taking care of all of our plumbing needs for the past 30 years. There has never been a plumbing issue that he couldn't resolve quickly and in the most cost effective manner. We've had projects that range from faucet installations and repair, to water heater replacement, to re-piping an entire house, and many things in between. Gordon's work is exceptional. He always explains exactly what is going on, and offers options for the repair, never trying to sell us something we don't need. He is incredibly knowledgeable, competent and honest. I highly recommend Mueller Plumbing for any project, large or small.
