Let me first say I've used Muetzel in the past. I had them come over and do some emergency repairs to my bathroom sink. The drain works fine now, but it came at a pretty expensive price of $600. Whatever. They came over and did the repairs and it worked. While they were at my house, I had them also prepare an estimate for installing some new water lines to a new kitchen sink and a new laundry room sink and washer box. The plumber took his good old time preparing the estimate, measuring everything and writing down every single part. It took about 1.5 hours to complete his estimate, which I thought was a little excessive. About 2 months later, they finally called with a quote. I had called and called and asked about the estimate before and they kept telling me they were working on it. When they finally gave me the estimate, it ended up being $2000 more than another local plumber who had already completed the work.
About 2 years later, I thought I'd give Muetzel another try. I called a few days ago to schedule an estimate to run a gas line to my new fireplace. They told me they could send someone out Wednesday between 7:30 and 8am. I thought, great! I can wait for them and still get to work at a decent time. Well, Wednesday rolled around and I waited and waited. At about 8:15, I called to notify them their plumber was late. They told me he was on another job and they would give me a call when he's 30-minutes away. I waited until 9am and called them to tell them I will no longer be using their service. If they can't give me a courtesy call to tell me their plumber would be at least 2 hours late, then they can take their business somewhere else.
Avoid Muetzel.
