I used All Valley Backflow for the first time about 18 months ago to complete the required annual…read moreback flow test required by the city. The following year I didn't even need to call Mike as he called me to complete the requirement. One less thing to think about. He completed all the required paper work and submitted to the city. Since then I have used All Valley Backflow for toilet repairs and the insulation of several hot water heaters for my rentals. What I like the most is that he returns calls promptly, shows up to the job as scheduled, and completes the job timely, with great workmanship, and is reasonably priced.

Isaack and crew not only did an amazing job in remedying an urgent water heater issue, but were…read moreavailable to respond immediately and arrived on site exactly when promised. Once he was able to diagnose the cause, Isaack sourced a hard-to-find/backordered component through his network of contacts and went far above and beyond in tracking one down so that I'd have service restoration within 24 hours (vs potential weeks of lead time). Additionally, he was in constant communication and provided clear and easily understandable updates on technical matters both over the phone and via text messages. It's rare to find this level of pure customer service and attentiveness in the Valley, and I was extraordinarily pleased with the results. Quoted rates are reasonable and transparent, especially considering the exceptional level of service/care provided. I cannot recommend Isaack and Master Pro enough.

It was apparent that he knew his stuff as he was able to quickly diagnose and repair the problem. He was so friendly and took his time to fully explain the issue to my husband and offer trouble shooting tips to for future issues. He made suggestions according to what he could afford and wanted to do and didn't try to cross sell or suggest things that weren't urgent. He came wearing a mask and was so polite and careful. I wouldn't hesitate to call him again as he was clearly a master of his craft who prides himself on outstanding customer service!
