"My tankless water heater went out on a Friday night, and the Water Heater Boys were able to replace it on Saturday the next day! Excellent customer service and professionalism. Will definitely call if in this situation again, and will tell my friends!"

"Perfectly. They cleaned everything up, explained how the system worked and how often it needs attention, and hauled away the old hot water heater. They arrived on time, worked steadily, and finished before dinner time."

"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."

"I met Gert when we hired him to replace our Tankless water heater. I was so impressed with is knowledge and concern to make sure the installation was neat and clean. The piping is literally a work of art. We met with Gert and Sergio to discuss the next phase. They removed all the galvanized pipe and installed 3/4" copper with a true hot water recirculating line for Tankless recirculating pump. Before they started work, they came in and placed protective covers over the hardwood floors. Sergio and his team replaced all the cast iron drains with ABS. They even opened walls where needed to get to the old galvanized drains to the sinks. They pulled up toilets and replaced the old flanges with new ones. All that's left is the sewer line from the house to the street. We will be calling Gert and Sergio when reach that point. Gert, Sergio and the whole crew have something you do not see that often anymore. That's integrity and concern for their customer. Also very conscientious of keeping our home clean."

"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."

"I hired Posiden to convert my traditional water heater to a new tankless water heater. David was quick to respond, offered great prices, and completed the work when he said he would. Itâ s difficult to find reliable work but Poseidon Plumbing went above and beyond and did a great job. Iâ ll be calling them for all my needs in the future."

"The contractor showed up on time and installed the water heater in a couple of hours. They hauled the old heater away and cleaned up the surrounding area very well. Will certainly have them do other plumbing jobs in the future."
