I tried to use my American Home Shield warranty at first. That cost me $75 to have someone come out and tell me they would not do anything unless I removed my toilet since my old house has no cutout for the line under the house. After removing my commode I called the warranty folks and they said they would not cover going through anything but a standard cutout. So, I called another service first and he went through the line and could not get his auger to bend correctly to go through the line. It kept going up the vent stack. I then called Morgan Leak Detection and Cliff Morgan came out, assessed the situation thoroughly and said he would clean it out for $200. A bit steep for a line clean, but he did a great job and ran the auger for a long time to make sure he got everything out. I am very good with tools and I can tell when someone else is highly competent with what they are doing. Cliff was. He was courteous, showed up promptly when he said he would, protected my floors from the auger (the other company did not), and you could tell he knew what he was talking about. I'd use him again.
