"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. "

"The Rinnai water heater was installed on 12/16 as agreed. I was absolutely amazed at the quality of the work that was done. The technicians arrived on schedule and completed the work ahead of the estimated time. They left the furnace room cleaner than when they arrived. The gas lines, air induction and venting PCV and water lines were neatly routed and installed. Everyone from the owner to his technicians were courteous and super helpful. The were expertly knowledgeable and follow through on all commitments. I could not have asked for anything more. I would categorically recommend Lorenz Plumbing ."
