Get matched with top tankless water heater repair pros in Round Rock, TX

"Scott was really polite and patient, was willing to answer any questions I had, and accommodate any last minute changes or issues that I might of had during the installation and upgrade to a tankless water heater. He did excellent high quality work on the installation."

"These guys were Amazing! Two months ago my pilot light on my 15 year old water heater went out. They were out within three hours to relight and give us a quote on a tankless system. The bid was very reasonable so I called the operations manager and asked him if we should move forward with the installation or hold off until the old water heater died. Naturally I assumed he would push me to replace but he said he would hold off until the old one died. I was completely impressed that they didn’t to encourage me to buy right away. Two months later on Thanksgiving it started leaking. I called Excalibar back on Thanksgiving thinking I would be leaving a message and they answered. Not only did they answer but they scheduled replacement of the hot water heater for Monday and it was done by the end of day on Monday. We couldn’t be happier with the service or the tankless product. I would absolutely consider paying a little extra to get the recirculating system so that you have “on demand” hot water. It’s really nice to jump in the shower and have hot water immediately."

"Appointment was made, I was contacted 30 minuted before to say they were en route, they arrived at the appointed time. (grade=A+) Inspected water heater, gave clear advice on WHAT to replace with WHICH product and WHY.(grade=A+) Repaired hose bib and told me why it had probably started leaking in the first place and why he repaired it the way he did. Work done quickly and professionally. (grade=A+)"

"I have going on 3 hot water heaters in 3 years. Nobody could properly diagnose the issue. This time it was bad and flooding so bad the ceiling was going to collapse. I just purchased a new Hot Water Heater 3 years ago and that company failed to diagnose the issue. The Technician from Roger’s new all his trouble shooting procedures down to a science. He looked at the heater up and down and inside and out. He said “Water Pressure”. We go outside and my water pressure was 95PSI. It was responsible for blowing up 2 Hot Water heaters. Problem finally fixed and no more worries. I am very grateful for the skill and integrity of Roger’s plumbing."

"These guys came always on time to do the work. Reported an issue after the job was complete and they showed up the same day and fixed. They installed Tankless water heater and did some extra plumbing work to make this work as per specs! Top Job. Collin is great!!"

"Jon @ Johnny Pipes was great with explaining on the phone the process with converting my tanked water heater to a tankless water heater. It was installed quickly. The energy savings are amazing and the install price was very reasonable. The install was very professional and i highly recommend his services! Thanks again."

"Awesome service. Very professional. We love our new tankless water heater."
