"Very professional and efficient all the way through the process. Emergency replacement of the water heater just before a holiday is no fun, but they were above and beyond with the challenge! Fast and excellent value. Professional installation is greatly appreciated!"

"The first visit lead to cleaning the area around the heater and burners and checking the thermocouple. Sadly that seemed to make it worse. Less than a week later No hot water for over 30 hours till the second technician replaced the thermocouple. All is perfect now. No charge for the second visit. The next step, if needed will be a tankless and their quote looks a bit steep. But I am really hoping I won’t need to go that far."

"Marcell and True Blue Plumbing were a pleasure to work with. He was friendly and took pride in his work and client satisfaction. Marcell installed a gas line for me in Napa within the same week of providing the estimate, and he even helped me flush out my water heater free of charge. I will definitely use him for any future plumbing needs. My profession is a property manager and itâ s hard to find quality vendors like True Blueâ ¦Thanks again."

"I requested a quote on Sunday night and was able to get the plumber to do an evaluation the following afternoon and provide me a quote which I accepted. He replaced and installed the 2 bathroom faucets that same day. He did a great job and I am very pleased with the work."
