My plumber recommended this company to me and I found them honest and capable. Everything, including cost, was clearly explained to me and my concerns about the durability of my seventy-year-old sewer line were eased. It was fascinating to watch the live feed from the camera as it scoped out the entire length of the clay sewer line both before and after it was hydro-jetted clean. Absolutely all the tree roots were gone and the sewer line was good as new. They have a lot of experience with "perma-lining", which I would like to have done someday.
