"Chandlers did a great job. They quoted the repair and got to work. We also added the replacement of the sewer line as the main water line was being replaced. Chandlers added two sewer cleanouts in the front for future access to the sewer and provide a convenient place to empty my RV black tank. I was very pleased with the rapid repair and accommodating the additional work. They made what could have been an ordeal but got it done in 4 days total. I would definitely recommend Chandlers again if the need arises for any other plumbing concerns"

"Jose, the service technician, was not only professional in getting the job done, he was also patient when explaining the drain problem to me and he was careful in replacing items that were taken out under the kitchen sink cabinets."

"JPC team did an excellent, professional job on our storm water sump pumps related project. (Two sump pumps were working; they did not need repairs.) 1) Cut and replaced two broken pipes; installed new valves 2) New float sensors installed and set to auto-start the sump pumps 3) long outflow pine, connecting to city's water drainage system, was cleaned using long snake and high pressure water pump combination. 4) successful final test with water filled in water chamber and sump pumps working 5) JPC gave warranty for work done and signed up for once-a-year annual maintenance visit in October."

"Never had such a great experience with any contractor. So grateful to Eugene, Artem, Nick, and Alex not only for the great work they did, but for the care and attention they put in for 3 straight months. My house is built kind of complicatedly and the water heater isn't located in the most accessible place, but they were able to make it work. Not only that, but Eugene found me a new tankless water heater that would also work with my radiant floors - not only saving cost, but space as well. To say they went above and beyond is an understatement. They came back multiple times to make sure work was up to par - never half-assing anything. Really hoping I don't have any reason to need to reach out again soon, but if I do, I know who I'll be calling. Also, special shout out to Jeremy, Karen, and Kathy for their logistical help as well!"

"Fito Plumbers installed a new sewer line at my house. I appreciate good customer service when I see it, especially when it is with a contractor. My experience with Fito Plumbers was a positive one from the very beginning. From the quote, all the way through the final signoff Fito's team was great. Fito was honest and kept in communication with me over the one month period that it took to get the permits. His team showed up when he said they would, they were courteous and they respected my property. They did not kill one plant on my property which is a first. They cleaned up at the end of each day and they restored the pavers to the point where I can not tell where they had to remove them. I also appreciate that Fito's team power washed all the utility paint markings not only on my property but in the street. My street is covered with paint from previous work by others. Overall, Fito Plumbers was competitively priced and went beyond expectations with the installation."

"Marvin is a very skillful and professional man. He is a very detailed and neat person and not rushing to finish the jobs. When he completed the repaired job, he repeatedly ask you to review and check over what he’ s done until I satisfied."
