Get matched with top tankless water heater installers in Castroville, TX

"I was expecting to have to wait a day or so before I could get my water heater installed. Instead, I had a new one delivered and installed within a couple of hours and the price was better than what others were quoting. Excellent service!"

"Kevin was very helpful and explained everything. Price was less than the big companies I talked to. Took only two hours and he took the old water heater away."

"He showed up and assessed the space, adequately recovered tools and everything needed for the job, and was quick and efficient - answered all of my questions and didn’t feel like a hassle asking them. Will be calling these guys anytime I need any plumbing work done!"

"The repairmen was very professional and experience in his craft, I was shocked at how fast they responded to my request. It is a known fact that electricians,plumbers, carpenters and etc. are very expensive, but three or four hundred dollars to replace just a water faucet is entirely to much. As stated previously, I hired them to replace my air conditioner and they did a masterful job."

"It was a pleasure to work with Justine from Prostar Water Inc. She was on time and provided a competitive quote. She was patient in explaining the different options I have. Definitely would highly recommend her."

"I had a great experience with the team who first came out and identified the reason I had no hot water to the replacement of the water softener which was the problem. I decided to replace the water heater as well because of its age."

"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."
