The owner is like an entire Mash Unit diagnosing the problem which in my case required a combination of snakes and a video camera snake down my clean-out.for approx. 200 feet. The cure was installing a new y section splice in two locations into both a PVC and asphalt paper sewer line behind my house. The problem was a fractured and clogged PVC clean out section and tree roots in a hole in the asphalt line section. The owner went out of his way to be there for me and worked into the night regardless of frigid weather and rain conditions and on top of that worked out a price that was more than generous under the circumstances. I have nothing but praise for him and will gladly recommend him to others.
