"This was the only service that provided me with a price over the phone before they came out. All the other services wanted to charge me a fee to just come look at the downspout extension, so I had no idea what kind of charge to expect. Evan was great, showed up on time and kept in communication with me on his arrival time. only took about 20 minutes from start to finish. "

Patrick started plumbing in 2000 and opened Lorenz Plumbing in 2019. With over 25 years of experience, we are your local, go-to, plumbing company. Our goal is to provide, professional, honest, and reliable service. We want to give you the best service for a fair price. Check us out on Google for more reviews from our customers.

"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."
