"Had a old 30 year 75 gallon leaking hot water heater. JIG Owner came out to the and assessed the problem and offered a replacement unit or upgrade to a tankless! I selected the tankless. Excellent installation, and removal of the old unit. Crew showed up on time, very professional and made sure I understood the warranty terms and conditions along with the operation of the unit. The owner followed up with a followup inspection to ensure I was happy."

"Mike came out and helped so much! He was able to diagnose a few things and gave us some great suggestions as to what things we needed to fix. Really loved the professionalism and expertise he brought. All the work was done quickly and efficiently. I'd go to Alpine plumbing again in the future, they do great work."

"Kayvan was a wonderful service tech! He was on time and professionally checked out the water heater and the HVAC system. He was so polite and friendly. He explained the need for a new filter in the heating unit and showed me photos of the unit located in the attic. He also offered to do a friendly deed for free, which I greatly appreciated, He’s a great asset to Service Champions!"

"Mr. Joe was not only professional, but personable as well. He identified my issue with my hot water heater, and fixed it expertly. Dr. Rooter treated me with respect and was overall a tremendous value. I saved the number, as Dr. Rooter is now my first choice for my plumbing needs. 10/10"
