"The entire project from start to finish was fantastic. Within minutes of requesting a quote I received a text with a time they could be at the house. Rodney called to ask some questions, gave me an estimated price and time. Rodney was great to talk to and was very knowledgeable and helpful. Rolando arrived a little early which was great. He figured out what needed to be done and gave me an estimate which was within the range mentioned and started working. It took an hour to complete. Rolando went over what was done and why. I was extremely impressed with Rolando, he was courteous, informative and did a great job installing the water heater and bringing everything up to code. I wouldn’t hesitate to call Better Water Heaters again."

"You will be so pleased that you chose The Tankless Guys to look after EVERYTHING and anything to do with plumbing in your home. Gert has been my go to professional for over 10 years for ALL my plumbing needs. He operates with the highest integrity. His top priority is to do what is in the best interests of his clients. Gert and Sergio installed my new water heater two years ago. Sergio stayed for much longer than he shouldâ ve after installation was complete. He took extra care to figure out how to program the timer for my existing hot water recirculator which was not part of the water heater job. He didnâ t have to stay, but thatâ s how Gert and Sergio are. True professionals willing to lend their expertise. Some plumbing companies out there send NOT very qualified plumbers to do the minimal and/or charge you a significant amount for unnecessary work. Gert is a straight shooter. He has saved me a ton of money to replace what needed to be replaced and NOT replacing what did not need to be replaced or fixed. He will tell you whatâ s the most economical and efficient and what you need to do to protect your home from future plumbing problems. If you want cut rate prices with NOT the most qualified plumbers, donâ t call The Tankless guys. If you are looking for a team who thoughtfully looks after your whole home and considers preventative measures that you might not have considered, Youâ ll be so happy you called the Tankless Guys. Remember you get what you pay for."

"The complete process from the quote, to scheduling, to the installation of the tankless water heater was excellent. It only took one week from quoting through the completion of the job. The installation was completed in one day. The team was cordial and professional. Furthermore, the price was competitive. I would strongly recommend Super Brothers for your plumbing jobs."

"Guy who came gave me good advice and advised that he felt my issue was not needed for repair. He didn't try to sale me any service as he saw no need. I appreciate a plumber who isn't trying to get work out of people whom don't need it."

"Replaced a filing water heater. The work was excellent. My water heater was basically blocked in by the incoming water and gas pipes, but the two-person team managed to remove the old heater, replace pipes as necessary, and get everything working again. Gave up-front pricing including permit inspection. Super professional crew."

"Jesus repaired the leaking water pipes behind the shower valve. It was Sunday, but his response was quick and he showed up on time. I think he is the best honest plumber I ever met. He did a great job with reasonable price."

"In & Out is fast and professional.   They bid our job in the morning, and were back that afternoon with new toilet tank flushing devices and had all four of them installed in our bathroom the same day.   They took away the old parts and the boxes the new parts came in.   They are knowledgeable, punctual and tidy.   Should we have any plumbing problems, I would call them right away!"
