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."

"First of all, we are happy with the finished product of our master bathroom and walk-in closet. We are NOT happy with the owner of this business and his handling of our project. Jeff took time to design our space over several meetings. He promised that he would be available to choose tile/granite/light fixtures/plumbing fixtures whenever we needed him. Timeline was discussed with a 6 week from contract start and a project time of 3 weeks. Permit submission was done by myself with plans drawn by Jeff. We failed the permit process with 14 items that were not addressed due to insufficient drawings. Additional time/effort was required by Jeff and us to meet the requirements to meet code, which pushed our project back several weeks. We also paid more for the project due to Jeff needing to insure his workers for our village (a cost he should have known upfront). With new drawings, we re-submitted and were approved for work to begin. I can't say enough about the FANTASTIC workers that Jeff has on his team. They were courteous and did excellent work and even suggested design modifications that made sense. One of our first tasks was to pick out a granite surface. Jeff gave us the name of a granite place and that he'd meet us there. He NEVER showed. We picked granite on our own that day. We ordered tile - on our own. We chose lighting, plumbing, fixtures, and paint colors - on our own. The next time and ONLY time we saw Jeff for the duration of the project was when he delivered the vanity and asked for money (same visit). The total project ended up taking over three months to complete. Due to various project modifications/additions, we had no idea what our final invoice would be. We waited and waited for some type of final figure. 8 months after the project was completed we finally received a remaining balance invoice for over $11,000. We were shocked to receive this invoice so far after the project was completed. Jeff explained that COVID and not having an office manager were reasons behind us not getting an invoice before then and that we fell between the cracks. While we don't argue the price, we did not appreciate the length of time it took him to get the job done, nor the amount of time before we received a final invoice. When we offered to pay $2,000 each month for the next six months we were sent a very threatening email offering us three options for payment in full NOW. Suddenly this money is due NOW when he has carried this receivable for 8 months already? We will NEVER recommend Artistic Kitchen Concepts (Jeff) to anyone in the future. His involvement in the project started out well, but dropped off to the point where we never saw him, had no further input from him, and didn't receive an invoice until 8 months after the project was completed."
