I called needing my main sewer line cleared as it was pretty clogged. I called about 7:30 am and a technician was at my home at 9, as promised. He installed an outside cleanout point (other was in crawlspace) and thoroughly cleared the sewer line. he also fixed a pinhole water line leak in the crawlspace and had all this done in just over 4 hours. he did a great job and I'd recommend mr rooter to my neighbors and use them again.
