Express Rooter Plumbing

I called late in the evening and gave my name and number for a call back. I received a call the next morning, saying that someone would be there by 11am. When the representative arrived, I told him of the problem. He said he could use the camera to have a better look. I was charged for him to put the camera down the drain. He advised me that the drain needed to be replaced, and that it would cost approx $4000.00. This was my first experience with a plumber wasn't sure what to expect. It was very pricey for 15mins, considering that nothing was really done and that I was told that estimates are free.
