We had a horrible sewer back up in our house. My son and his friend decided they could clear up the problem themselves but they were wrong. We called Cannon Plumbing because they had just done some work for our neighbor. They showed up just a couple hours after we called and within a few minutes the plumber had figured out how he needed to clear the drain. What I really liked is that he kept explaining to my son why and how he knew where the blockage was at and what it would take to clear it. 30 minutes later the blockage was cleared and the plumber was cleaning up. I Loved that he cleaned up our mess and didn't make it worse. These guys really know their stuff and the cost was much less than I imagined too. I hope I never have a blockage again but I guarantee if I do I will be calling Cannon Plumbing.
