"Tankless water heater went on the fritz last Monday. Submitted HomeAdvisor request for quote and Rob called almost immediately. Took some pictures of the old unit and plumbing and had an all in reasonable estimate. They came out next morning (to the city no less) and installed new unit in a few hours, explained everything and tested and was within estimate. Very knowledgeable and professional. Have great hot water on demand. Wife is very happy as our old Eternal tankless struggled ever since we moved in 3 years ago. Very happy with the recommended Navien and installation from RA."

"I thought it went well but took longer than I expected. Mechanic Leo bought the new tank and pipes in when he arrived. I believed Leo arrived around 7:30 pm. He completed the installation around 11:30.pm Leo went out to his truck, stayed outside for a long time, in fact, my son Vann went out to ask him what was taking so long. When he came back in, Leo told me there would be an extra $100.00 We explained that we had been quoted a price of $1,300.00.. so he said to call the i office and they would straighten everything out, That’s why I called the next day. Everything seemed okay. When I notice the water was much slower, I called to let J&S know. The person asked me a few questions and advised me to check the faucets. Well, that didn’t work and the water was not as hot as before the installation. I called again to explain to J & S what was happening. The person there told me that they didn’t have to come out, and I still owed them $100.. so that's why I called Angi So I decided to check all of the faucets and I realized that the water flow was not coming out properly from any of the faucets So this is what happened. I am just appalled that they haven’t come out or called as of this date. I need them to come out and check this out, something went wrong. We could do a FaceTime inspection that would show the flow of the water."

"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!"

"Patrick was terrific! Very personable, down to earth, and professional. We had his team install a tankless water heater and while he was here we decided to have a few old toilets replaced and we had him reconstruct our washing machine drain set up. Patrick’s team was very neat and very efficient. Everything works and looks great. We could not have been more pleased with our decision to hire Patrick. I would 100% recommend Lorenz Plumbing."

"These guys are great and were definitely the best value. Very knowledgeable and up on the latest technology and research in home comfort. We discussed some possible upgrades to improve efficiency and comfort and I was very confident in my decisions. Installers were professional and hard-working. The owner, Tim, is a really nice guy and I didn't feel rushed or pressured as we were talking through the options. Office staff was on the ball with gentle (not aggressive) follow ups. Also, TDH Mechanical guarantees the system for 12 YEARS parts AND labor!!! So if something, anything goes wrong with the system (other than you bashing it with a hammer or like your basement flooding) they come out and fix it at NO charge. That sealed the deal for me. It was refreshing to see somebody stand by the product and workmanship like that. I give them the highest marks."
