All City Plumbing, Air & Electrical
We have an older home in West Covina that has had plumbing problems off and on for years. We’ve had many different plumbers and specialists look at our drain pipes, including several quite recently. We got different stories from each of them about what was wrong and how to fix it. Only one got it right, as the work ultimately bore out. Some wanted money just to show up to diagnose the problem. All City, and Antonio Peters in particular, however showed up, without charge, and gave us all the time we wanted to discuss and understand our problem. It was complicated and we needed to fix it without tearing our newly remodeled house or driveway up, Antonio gave us enough input and latitude to choose the best way for us to go. They utilized a boring technology that went under our driveway and around our house. They were not the cheapest option, but we feel we saved money overall as well as future problems and they worked with us on the pricing. We now have almost all new drain pipes and we didnt have to destroy or redo our home.
Once the work started he and his crew were just as attentive, and they clearly knew what they were doing. They proceeded with their work, but listened to our questions and concerns. They were responsive to all our additional requests. We found their crew members, Ivan Duanas, Alex Sotelo and Jose Pineda to all be pleasant, hard working and helpful when asked. Jose spent almost a full day cleaning after almost all the actual work had been done. He even swept the small amount of dirt that had ended up in the street in front of our house.
