"I've used their service three times. The service they provide can't be beat. The first time I used them was after hurricane Irma when my pump head (I think that's what it was called) stopped working and the house started to flood. The septic water was not being sucked out the septic tank into the drain field causing sewage/water to build up and back up into our house. They came out the same day and figured out the problem and since the part I needed would not be available until the next day (Saturday) they pumped out the the septic tank given us the ability to use our water without it flooding for the night since by pumping out the septic tank it would have more space available to store waste. The next day they came out and installed a new pump. Everything worked perfectly thereafter. The second time they came out was because our water was backing up again which was about a year later. We were concerned since we just had the pump fixed. They came out the same day to access the problem; come to find out the switch to the pump had been accidently knocked into the off possition - probably by the lawn guys we hired. So he flipped back the switch and it started pumping and everything was well. We did feel a little silly. But everytime they respond to our calls we learn something new about having a septic tank. (By the way we are first time home buyers.) The next time they came out we had another leak which we later found out had nothing to do with the septic tank and the plumber who came out quickly isolated the problem. This time it was due to a leak in our shower from someone who had recently remolded our bathroom. They didn't even charge us the third time because they never had to dig which was a relief! So this time we got insurance involved and got our bathroom repaired, we needed a new shower pan liner, and now we are hopefully done with leaks. Ooh the joys of buying a new/old house. I am very grateful for Rooter One they are the best!!! I will always hire them for my plumbing needs and septic pump out. Love Love ❤️ their team."

"Exactly as planned without a single hitch. A clip had somehow become flipped up during installation resulting in a very small but immediately noticable leak. I called Eric Payne and the crew showed up the next day to implement a complete repair. Additionally, and I think most telling of their attention to detail and customer focus is this; During the normal course of a standard roof replacement, it was discovered that there was major wood decay and rot that caused extensive mold and other visible/structural damage. The THR crew never skipped a beat. They brought in additional supplies and effected a complete repair."
