Customer reviews
“Daniel was very pleasant and took care of our clogged shower drain promptly. We also had a water filter put in and were missing a part. He went and got the part and returned the next day to finish the job. Great service.”
“Josiah and Dillan did an amazing job. My new home had several gas leaks. They came out immediately to identify the leaks and had everything repaired the following day. He also installed a new tankless water heater for me. Great communication and quality.”
“Elite Rooter Inc. made plumbing easy. Every worker was kind, professional & knowledgeable. I felt confident with the people i let into my home. We had got a new water heater, water filter, & a complete redo of all pipes. They had all gone above & beyond in every aspect.”
