"Overall, it was excellent. Jerry (the owner) came out and was very straight forward as to what needs to be done. Price (compared to 6 other companies) could not be beat. Work was scheduled reasonably quickly and went smoothly. Problems were discovered after installation and when made aware, Jerry and his crew made sincere efforts to set it right – and were able to solve the issues in couple of visits. All of the crew and management went out of their way to ensure that we were satisfied with the work and overall result. Would definitely consider Liberty Plumbing for future work."

"Overall great experience. Donald, the inspector, arrived early and patiently waited with me for my real estate agent to arrive. Donald did a thorough inspection of the inside and outside units. He was very knowledgable about pertinent laws and regulations and took his time to explain them. He also explained that the HVAC unit is old, but functioning and that it may have to be replaced in a couple of years. When that day comes I will definitely call Carini again, and ask for Donald."

Hydro jet uses water at 4,000psi to clean the inside of the mainline drain which connects all the home's drains to the city's sewer system.
Using a snake we can go through the cleanouts on the side of the house.
With the cleanouts snaked, and the blockage located, we can send the hydro jet through the sewer vent and flush out the blocked drain.

"The Mr. Rooter was very professional. He arrived on time, explained what he was going to do and discussed with me at length the type of replacement toilet that I had in mind. He finished the task quickly and cleaned up very well afterwards. A really good job."

""One Water" employees are professional and courteous. System was installed in a few hours. It's been 2 weeks since we got the unit installed and we are happy with the quality of water that we are now able to get from every faucet in the house."

"They initially re-plumbed our entire house years ago so we are still under a service contract with them. They do excellent work. We have had no problems with them. They were very professional. There were only about two of them here at a time and they come do whatever they have to do and then, the construction crew came in after them and did what they had to do. We are very pleased with them. A lot of companies would not work with construction crews that way, but they do."

"Tarpy was recommended to me by an electrical contractor I trust. Scott spent the time needed to go over all options for repairing or replacing my old system. I decided to go with a full replacement, and to install new mini-split systems throughout the house. Bowen did a great job working through some tough challenges to work the cleanest install possible. We needed to make a few changes to the install plan along the way and, to his credit, the owner, Broc, stepped up and worked out a fair way to get the job done and done right. Jessica was patient and thorough with the followup paperwork. All in all, a great team, I highly recommend Tarpy, they're an honorable team that delivers on what they promise to do."

"provider arrived on time and after brief explanation of what I wanted done, he went to work right away in replacing old water shut off valves.  Very professional, polite and made sure everything was cleaned-up.

"I can't describe the sound of the blockage when it was cleared, but there was no question what the sound meant or the smile on my face. We've used them several times over the years and service has always been great. I showed Jose M the issue and pointed him to the closest clean-out. After quite a bit of effort it seemed he was running into a serious obstruction. Jose asked about another clean-out and started searching around the perimeter. He found one that I'd forgotten about as it had never been used, and sure enough, water was backed up in it. He snaked it and ran into a major obstruction about 35 feet in. After repeated attempts to clear it, he suggested we needed to camera the line. He called 'the boss' who headed over, and Jose continued trying to clear the line. And Murphy's Law, just before the boss arrived he got the line cleared. Again, what a wonderful sound! Greg arrived shortly after and even though the line seemed clear, ran the camera through it (no extra charge). Good move, he ran the camera to the city's line, and pointed out a couple spots that were problems waiting to happen. Knowing what we may be facing in the future is a relief. My original estimate was $77. Final cost $77. And that was on a Saturday! VERY IMPRESSIVE!!"
