"They were able to assess the job with a couple of photos to recognize the old power-vent heater I had and what a replacement would cost. We discussed options, and they could upgrade me to a tankless heater for a relatively small increase. Was in and out fairly quickly and we were very satisfied with the new tankless."

"It couldn’t have gone better! Carl was experienced, knowledgeable and friendly. Plus, he smelled gas which is why he replaced the valve on my water heater. It was a great visit!"

"They gave me several choices for the water heater where other companies only carried one or at least did not offer others. I also appreciated the fact that they gave me a quote over the phone. They were knowledgeable about their craft and expedited the installation once I had made a decision. I also liked that I could buy the toilet myself and they quoted just the installation so I did not have to pay the mark up for the hardscape. I am changing all of my plumbing needs to this company."

"I originally spoke with the owner Patrick Lorenz,, who gave me an idea how we should approach this problem. I thought I needed a tankless hot water heater, which is very expensive but he gave me an alternative that I’m happy with. I had a tankless hot water heater in the past and that’s all I knew about getting instant hot water. The system he set up for me is just as good and cost pennies on the dollar compared to tankless. Might not be good for everyone, but it’s served our purpose. And I’m 100% satisfied I would highly recommend Lorenz Plumbing to anyone looking for a professional job and save a few dollars."

"They came and they installed everything in one day. I just stayed out their way. That was all. Yes, I have an older house which has baseboard heat. They had to install the evaporator in the attic in the crawlspace of the house. They couldn't install it in an traditional way."
