"We had a issue with our shower and regulating the hot water. We had Kevin put in a new handle and cartridge system. Kevin did a great job installing and cleaning up afterwards. Would hire again."

"I called Water Heaters Only out of desperation on Sunday...Seth @ toll free # was fully aware of our tenants being without hot water for 2 days and was able to get a technician out on Monday morning. Monday @ 5 pm, hot water was up and running. David, the technician knew what had to be done to get the heater up and running. The next day, we did have a hiccup with a part but David came out immediately and tweaked the part -- all is good. Here is what I like -- 1. no sales pitch. 2. David gave me a plan b for possible additional work. 3. this company is available 365 days and you dont have to wait for parts to be delivered from out of state. 4. Water Heaters Only has their own facility for parts."

"Very professional. Explained everything carefully and didn’t mind answering our questions again and again. Jake installed a tankless water heater in a matter of hours. Left the area looking better than he found it. Reliable plumber and reasonable/affordable pricing. Will definitely recommend Jake to all my friends."

"Original estimate and proposal was handled in professional manner. Everything was fully explained and there was no pressure or "snow job". Everything was itemized and put in writing. The "free" hot water heater was not needed so received a credit of $1300.
The five man crew arrived on schedule and got to work immediately.  Met with supervisor Mark and foreman Jose and reviewed job.
The crew laid down tarps for dirt control (looked good at first, but wasn't that effective. Attic insulation was still tracked in house  They did attempt to vacuum everything up.)
Crew didn't have a ladder so they used mine. No big deal.
They all worked really hard and there was no loafing around. Had the walls opened and new pipe laid out and ready to go the first day.They didn't hesitate in working late. Made the ordeal of having to have a re-pipe bearable. It was great to still have water all day and that night.
The crew were very polite and friendly and we enjoyed their presence.
They really appreciated the free lunch we gave them and helped cement our relationship. They all deserved a "Gold Star" for their outstanding work.
The next day layout was completed, old pipe removed and new tied in. New piping was flushed and  pressure tested. No leaks.
As a former building inspector, I was very impressed by their professionalism, work ethics and attitude. It's very rare to have someone "do it right the first time".The following day the drywall came and repaired all the walls that had been demo'd. Outstanding job.
 Only a few negatives:
Cleanup. 
Attic insulation that had been pushed aside was not put back.(still not done)
They also missed some shock absorbers which the building inspector caught. Jose came back the next day and took care of the them.  Bathroom exhaust fan had been stepped on and pushed down below the ceiling. Drywall man attempted repairs. OK..
Piping could have been flushed a little longer to get all debris out. Minor.
Overall I am very pleased with the work. Price was a big OUCH!
UPDATE!
It has been several months now and I find the installation was not as great as I thought.  Rather than moving the ceiling insulation, they installed the pipes on the roof rafters. Pipe insulation inadequate; water too cold in winter and scalding hot in summer. Don't let them take short cut!

"My water main that goes from the street to the house had to be replaced. I called 2 other plumbing companies. One did not even bother to return my call until 5 hours later and another one tried to rip me off on price. I called this company at 7pm at night and they returned my call within 10 minutes. They set my appointment the next day at 11am for a free estimate. They came right on time. Joseph was extremely knowledgeable and even called his supervisor so they could put their heads together to figure out how to do the job for the least amount of cost to me. They used this trenchless technology so they did not have to dig up my entire yard. Once the price was agreed to I was expecting at least a few days to start. I asked them when they could start and Joseph said "right now". The digging was minimal and the job was completed by the end of the next day. They took care of everything from the pulling of the permit to the inspection by the county. After the installation was complete and the inspection was done they filled the hole they dug up with fresh cement and the hole in front of my house with fresh stucco. Everyone was a true professional who worked on this job. I cannot be happier and I would give all the people on Joseph's team who worked on this job my highest recommendation. A special thank you to Tony who stayed until 9pm in the cold the first night breaking cement and digging a hole in my yard so the job could be completed the next day. My water pressure is twice as much as it used to be. If I ever need anything plumbing related I will call them again."

"It was a certain price for him to come out and fix a leak. He installed the water heater either the next day or maybe the same day. It was right away. I had him one day, and then the next day we noticed water coming out of our water heater. So I called him and he was on his way taking his daughter to school, which is just a block away from our house. So he stopped by and then went to work and brought back a new water heater and installed it. He is a nice person. You can tell. He just wanted to help us. He knew we needed a water heater and he fixed it for us right away."

"I got this company from Angie's List and they were excellent. They added a drain out for me and it was so bad I wouldn't have water buck up, I have really bad back up. They put some drain pipe for me and they also rooted out my sewer line.They came in fast but I ended up involving the insurance for some of it because I had a flood in the bathroom which wasn't covered so I let them do that."
