"The individual who came to my house to give me an estimate did an outstanding job explaining everything. Due to the extensive modification that would have been required to install a tankless water heater I replaced the existing water heater in kind. I would not hesitate to hire them for future work."

"I hired Superior Plumbing and Drains to install a gas water heater in my home. They provided a 10 year full warranty and cleaned up after they finished the job. Austin and Zach had great customer service and were extremely professional. I will hire them for all my future plumbing needs and I would recommend them to anyone who needs plumbing work done in their home!"

Customers say: Quality work

"This business is fast,efficient and provide excellent work. I dealt with owner and two water heater installers and they were all very professional and did awesome work. Price was great also, as I had priced others. I have a home warranty and they said it would take 3 to 4 days and extras not paid by warranty would be almost as much as this company charged for larger water heater and complete job. And they got it done in less than a day from my first call to job complete. Loved their service!"
