"My understanding is that the guy that came out to install my new toilet and bidet has actually had more experience with commercial plumbing but you would never know it. He was very personable. Showed up a few minutes late but called and let me know he was running behind and then showed up when he said he would. Very conscientious. Seemed to know what he was doing with the bidet install even though it doesnâ t seem that would be typical for a plumber. Made sure everything worked as it should and then cleaned up after such that my wife couldnâ t even tell work had been done. His prices seemed reasonable. I have him scheduled to replace a water heater soon and just as an example his price is significantly less than the other two bids I got. And Iâ m not sure who it was that called but a few days later a woman called to see if I had had a good experience. Needless to say I answered YES!!"
