This people at $100 for line, is no cheap but also didn't finish the job well. I got a main sewer line clog with roots. Typically I clean/kill roots every year or two and is good. This time the guy cleaned a first spot with roots, then he didn't went thru to test the whole line and left a second spot that started cloging my line under two months after his visit. Instead that guy tried to sell me preassure cleanning under a "$400 supper offer" take it or leave it offer using scaring tactiques. Water pressure is good for grease but not for roots typically. They din't have root killing chemicals that typically can improve the job with a small cost. Now two months later I called a new company that for half the cost has gone thru the whole line and showed me how this Dial a Sewer Man didn't finish his job after failing to scam me with other products.
