"Removed old water heater and installed tankless. Explained what needed to be done. There was some misunderstanding on what was needed that I said I would accomplish prior to their arrival. They stuck to their estimate even though they had to do additional work."

"I used Plumb Tite to install a tankless water heater. The pricing was straight forward and fair. The service technician was professional and courteous. He showed up on time and cleaned up the workspace afterwards. I would definitely recommend Plumb Tite."

"James did an outstanding job. He contacted me 15 minutes after he received my information from Angi. We set up a time and he arrived 30 minutes after we talked on the phone. He provided me a quote. I hired him and also had him do other work while he was there. He replaced my water heater, replaced outside facet, plus a couple of minor things that he found. He completed everything to perfection within 4 hour of me submitting my request. James was very professional,, very affordable, and answered all my questions to my complete satisfaction. I have added James to my list of experts to call and he #1 on my plumbers list now. I would definitely hire again."

Customers say: Quick response

"Very honest and professional. He gave me all options including cheaper options besides a full replacement of my water heater. I appreciate his honesty and professionalism. I highly recommend. The person I talked to before him from another company tried to get me to replace without even looking at my water heater. Glad I found him."
