"Jason, Mike and Rick are the best! I was having a problem with septic smell in my vacation home in Sullivan County. My local plumber had no interest in actually diagnosing the problem. All he did was put band-aids on the problem and said "see if this works). Needless to say, nothing he did got rid of the problem. I called 5 other plumbers in Sullivan County and no one even returned my call. I found Jason on Home Advisor. He is not in Sullivan County but his listing said they service the area. I called, got Jason on the phone and we made an appointment. He came in and said until he opened the wall he could not be sure, so he gave me a best case and worst case scenario, price wise. Turns out, it was the worst case....my entire drain line needed to be redone from the house to where it hooked up to the new septic system. They came back dug a trench in not the best of circumstances because of the weather and re-plumbed the drain. I will be using them as my plumbers from now on! I don't think you'll find a more competent plumber serving Sullivan County! And Jason is a hell of a nice guy!"

"Came and went without me even having to be home..Installed a new sump pump in the crawl space of our home on Orange Lake. Wouldn't hesitate to use them again."

"Came as scheduled. Installed new heater in restricted space. Did a great job."
