"Work went great. Our initial call was due to a leaking water heater and leaking shower valve. I called Legend Plumbing and Jesse came that morning. He observed that we had galvanized piping, and getting the house re-piped was on our list of things to do. Legend Plumbing gave us a 'package' bid in which we were given a significant discount on the water heater replacement, plus repairing the shower and re-piping the house and water line leading from the water meter to our house. We had to have the water shut off twice, and they worked with us to accommodate our schedule. When they were scheduled to work they arrived promptly, and cleaned everything up before leaving for the day. We are extremely pleased with the work and will definitely hire Legend Plumbing again."

"I needed my water heater fixed. I needed same day service, fair pricing, and exellent quality work. After having two Company’s come out I did not feel comfortable when they were pressuring me into a maintenance plan when all I need was a repair. I called Fabstatic Plumbing.

The technician thoroughly explained what they were doing and how long it would take. We had several quotes/options, but Prostar Water definitely provided the best product and service for the money!"
