"It went well. The plumber was on time, kept his word, had to come back - showed up as promised; not inexpensive but we were expecting it to be more based on an earlier assessment by a different plumber."

"Great job. Anthony did a complete review of the house and the current venting and recommended the proper size for the AC. The installers and electricians came 3 days later, did additional wiring and piping and installed the entire system in 5 hours."

"They said that they would be at my place between 8-10am. They showed up at exactly 8am!! The technician answered all my questions, he kept me informed as to what he was doing. We chit chated, he was very respectful to a senior citizen (me!!). I plan to hire Plumbing Pus every time I need the plumbing worked on and I would recommend them in a heart beat. Wonderful customer service!!!!!!"

"I called several popular plumbing companies to replace an old dripping shower/tub faucet in the guest bath. All wanted to use their fixture and cut the shower tile to fit the new fixture, so I gave up. After a year or so, I joined Angie’s list and found Top Notch plumbing. Gordon had some fixture recommendations, but allowed me to purchase my own fixture that was compatible with my current installation. The overall install took about 3 hours. Gordon took care during the work to not damage any existing tile or carpet. He knows his craft and performed a very clean and professional install. Overall, I highly recommend Top Notch plumbing and will be saying goodbye to the popular TV advertising plumbers. Thanks Gordon!"

"The plumber showed up on time and was very pleasant and professional. He completed the job in approximately 1/2 hour which I thought was amazing. He took all packing materials with him and left the counter spotless. He did not try to oversell me any additional items over and above the work I asked to be performed. I would definately use Vista Plumbing in the future."

"Expertly installed! Crew cleaned up afterward. The only way you could tell they were there was the shiny new copper and new tank. I will absolutely utilize Jax for my future plumbing needs."
