"I liked the statement made by Darryl in his synopsis of his co. and work experience. His closing words were "It's never wrong to do what's right." Based on that philosophy, I was convinced he was my man. I was right. He worked very hard to diagnose and solve my septic problem. He explained my options and we chose the right pump. He was unable to get the item locally and so called around to find it and drove some distance to purchase the sewage pump that I needed. He was easy to work with very honest. To top it all off, he charged a more than reasonable fee and completed the work the same day. I would highly recommend Darryl, a knowledgeable man of his word who does what's right!"

The average cost to snake your main sewer line is around $250 for a simple snake. Most sewer line specialists charge between $45 and $200 per hour for main sewer line snaking, so the time involved plays a major role. The price you’ll pay will depend on the severity of the clog, the item causing the backup, how long it takes to remove the item, and more. A more severe issue that requires unclogging a main sewer line will cost $3,100 on average.
