"Gustavo from Escamilla plumbing is a pro thru and thru. I gave him a tough job that I wanted to tackle but didn't have the necessary tools or time to tackle. I had him relocate the water heater lines and install a tankless water heater, remove steel pipes and redo drain lines. The kicker for the water lines was access next to a furnace and new gas lines that needed to be run due to insufficient gas supply. During the project we found micky mouse water line taps that needed to be removed and the house water shutoff valve that failed to closed completely. Lots of unexpected work but he gave decent quotes to complete the job. He is quick, doesn't cut corners, and gets the job done. I wholeheartedly recommend him for project a homeowner wouldn't touch or doesn't have time to do."

"When a pipe burst in our garage, we were pretty stressed trying to figure out what to do. Ron came out right away, shut everything off, and replaced the section of pipe that broke. He worked quickly but also took the time to explain what had happened and how to avoid it in the future. Really grateful for how calm and professional he was in a stressful situation."

"The arrived to do the estimate on time. The estimate was very reasonable as we had a water heater replaced on the other side of our duplex by someone else 2 years ago (we were expecting the cost to be much higher then it was 2 years ago). The gentleman that came the next day did a great job of installing the new water heater. We were so impressed with their professionalism we are having them do another estimate on some landscaping plumbing."

"Rarely write reviews, but I had to take the time to recognize the incredible service I received from Green Arrow Plumbing. From start to finish, this was hands-down one of the best service experiences I’ve ever had! I originally called for a relatively simple job replacing a shower head but while they were here, I also mentioned a persistent issue with my main house drain being clogged. Without hesitation, they jumped into action and took care of both problems quickly, efficiently, and with zero mess left behind. They were punctual, professional, and friendly . They explained everything in simple terms, gave a fair and honest quote, and stuck to it. No upselling, no surprises just quality work done right the first time. If you need a reliable, honest, and highly skilled plumber I highly recommend Cornelio. I’ll definitely be calling them again for any future needs. Thank you for making what could have been a stressful situation completely stress free!"

"I had a backup in my main sewer pipe and Jess Plumbing came out and did a thorough inspection, he then found that my main sewer pipe was incorrectly installed by the previous installer. To make a long story short, this guy knows what he is doing, has the equipment including cameras and an excellent team. They did an AMAZING job at a FAIR price. Replacing the main sewer pipe is no easy job, but they were able to do it and do it right. They also cleaned everything up at the end of the day and even planted back the plants that had to be removed during the process!"

"Victoria Cedillo's team (Lead: Victoria. Team: Victor, Ruben, Richard, Pedro, and I am sorry if I missed anyone...) from Mike Counsil Plumbing did a wonderful job with our main line sewer and installing new sewer lines! Victoria's manager, Glenn, is very nice and patient. He provides guidance to Victoria's team to diagnose our sewer lines, provide recommendations and detail estimation options to us. We feel comfortable working with Glenn and Victoria during this job, and I have learned a lot regarding proper sewer lines and water lines connections. Victoria also took me into our crawl space and showed me the new sewer line at the last phase of the job. Victoria and her team are really professional and they've provided excellent customer service experience! For all the jobs they have completed, Victoria will provide photos and let us know what the current status of the job each day. Victoria is very considerate and she makes sure that we are able to use kitchen and bathroom at the end of the day (They will temporary connect the lines), and we really appreciate that! They also make sure the working areas are cleaned and covered up properly each day (if there is a wall opened) since there are rodents from our neighbors’ backyard. Mike Counsil Plumbing and Victoria’s team is knowledgeable with the city laws, proper line connections, and permit requirement. I was surprised to see a plumbing company that has their own work inspector (In this case, Dan B., was the one who came to my house for the final inspection. Thank you Dan!) to make sure all the works are according to code and it was done correctly. The works that were done at my house require city permits. Victoria makes sure we feel comfortable with the city inspection and she was present at the inspection. The company representatives such as Sabrina and Marissa are very friendly and easy to talk to. Comparing to other plumbing company, their price may not be the cheapest, but I can really see the quality in their work (compare to another plumbing company we hired years ago…). I highly recommend Mike Counsil Plumbing because I can trust their work and truly see the quality! Thank you, Victoria and your team for all the hard work! =)"

"Leo did a very extensive plumbing repair that required digging through my bathroom floor and replacing a huge pipe to the outside. He also prepared and installed piping and fixtures for a bathroom remodel. Always showed up when he said he would and had a great crew. Cleaned up as well. Would highly recommend."

"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."
