"It was an absolute pleasure working Carmen, Frankie and team. I recently moved in a mobile home and I had them assess my tankless water heater that was giving me problems. With freezing temperatures hitting hard, it was very important that my family had hot water and overall a working water heater. They were able to recommend a new option and promptly install it. Communication was excellent and the overall experience made me feel confident I can rely on Carmen for any water heater needs. These days good service seems to be minimal, Garden State Water Heaters exceeded expectations. Thank you! - Max Hines"

"Ralph and helper Peter arrived on time, went right to work, highly skilled, kept area neat and cleaned up fully after finishing, improved work done by previous plumber, also did two unrelated plumbing repairs for washing machine and a hot water line. Dealt with 1955-built house conditions, first rate results. Very happy with heater, work performance, cleanup, and price. Old heater pickup done separately."

"Kyle and Justin installed a new 75 gallon water heater in my home this past week. The job was extensive due to need to remove incorrect pvc piping then install proper grade pvc to meet code. In addition they replaced and re install rigid piping for gas lines that apparently builder had not done correctly (shorts cuts!) this was also verified by another plumbing contractor of which we brought in for an estimate. So glad we went with Water Mac to do the job. Kyle and Justin's work was outstanding! These guys are nice, honest ,competent and fairly priced. I highly recommend them. Tammy Schoffelen"

"Travis and Elvis were very professional on the phone. Travis provided detailed information and answered all of my questions to better help me understand between options when I was choosing a new water heater for my home. Travis provided me with a free estimate and stayed within the price range we agreed to when completing the job. The water heater was installed in a timely manner. I also received a follow up phone call to check how the water heater was working and if I had any questions which I appreciated. I would definitely recommend hiring this company and plan to use them again in the future."
