What reviewers praise
Technician Andy stayed on-site after discovering issue was city-side — no charge, full transparency documented
1 cited review
“This review is for Andy Hernandez from Superior Plumbing who was fantastic to work with: professional, knowledgeable, and more importantly, honest. I had an issue with a clogged toilet that turned out to be on the city side. Andy took it upon himself to stick around to ensure all was good on my side before leaving.”
Completed a repair competitors refused to attempt, saving customer thousands of dollars
1 cited review
“Andy was able to do a repair that the competition didn't want to attempt, saving me thousands. Superior Plumbing is appropriately named. I will be calling the back, but hopefully no time soon.”
Upfront cost and process explanation before work starts; text notification when tech is en route
1 cited review
“Our kitchen sink backed up Christmas night (of course!) and when I called this morning I received professional help, a text when my tech was on the way, and an excellent repair when he arrived. Andy was super personable, and explained the process and the cost up front.”

Water heater installed 8 months prior threw error codes twice in 6 weeks — required follow-up visit; manufacturer defect, not workmanship, but added customer time
“This heater was installed by Jose at Superior Plumbing, 8 months back. Jose did a meticulous job, replacing pipe connectors, putting in new shut-off valves, securely strapping the tank to the wall studs.”
Keep it in proportion: these concerns are cited in 1 of the 5 reviews we analyzed. Most reviewers report positive experiences — see the full rating picture below.

“Excellent experience. Andy was able to do a repair that the competition didn’t want to attempt, saving me thousands. Superior Plumbing is appropriately named. I will be calling the back, but hopefully no time soon.”
“The discharge tube of my water softener broke and the water was using out and spraying everywhere. I had to shut off the main valve. When I called Superior Kimberley immediately arranged for Andy to come and replace a new tube. Andy did a great job and was very efficient too. Thanks, Superior!”
