"Perfect! I called Western Rooter the AM my disposal went out. They were at the house the same day, at the time they stated they would arrive. The work was done efficiently and professionally and completed within an hour. I have called on Western Rooter for many years for various plumbing needs (clogged drains, replace water-heater, replace main water line, etc.) and have always had great, timely service at reasonable $$$."

"Response was amazing and fast. Arrived on time and kept me fully informed. Professional with complete set of moisture/ leak detection tools. Answered all our questions. Would love to recommend them."

"⭐⭐⭐⭐⭐ Service Flow did an excellent job replacing my old water heater and piping everything in with copper. Their professionalism, workmanship, and clear communication throughout the entire process really stood out. The job was completed efficiently and to a very high standard. I’m very happy with the results, would highly recommend Service Flow, and will definitely be using them again in the future."

"Wonderful James is an amazing Plummer. I would recommend him to anyone or any business to get quality work done as professional service!"

"As expected, I got bombarded with several texts/calls/Angi messages as soon as I requested a Water Heater replacement. I waited for a human to leave a message instead of automated systems, which was Paul at Complete Plumbing located in Claremont. Same day replacement, haul away, and install of a 40 Gal. Bradford White was $1595 (2 year labor water, 6 year manufacturer warranty). Michael did the installation and had a delay from the first job, but Paul kept updating status and the install time wasn't much later than the original estimate. Michael answered all my questions and concerns."

"I have a technician coming Friday Jan 30th,2026 to check/repair the refrigerator. They got back to me quickly for a appointment. "

"Project involved major repair of main sewer line, requiring installation of clean-out, jetting, and re-lining. Company seems very well equipped to tackle any size job. The 7 workers that were involved at various times all seemed to be well trained. Michael I, the lead plumber, is very intelligent, knowledgeable, and good to work with. Very nice people all around."

"Wesley was extremely responsive. He made all efforts allowing us to continue doing our business at home while he was assessing the problem, assembling his crews, and obtaining a City permit. We were well informed of the progress. His crew did an excellent and clean job, working long hours getting the job done. Including excavated to a depth of 10 feet, patched up our concrete driveway and patched up the AC roadway nicely. Wesley even found time to replace our kitchen faucet and under drain without extra charge. Don’t believe he would be the cheapest initial estimate you would get. We would definitely ask him for all future plumbing needs."
