I have been dealing with another plumbing company for years. After repeated backups in the basement, that company came and replaced my outside sewer drain. Everything worked fine. A couple months later, I started having backups again. I called the same company and they installed a new drain inside. I thought we were finished. Within the first month, I was getting backups again when running the washing machine or using the laundry tub. This time I called Express Rooter. Jason ran a camera inspection and said that the drains installed by the other company were fine, but they had neglected to notice that the bottom of my cast iron stack was rusted out and collapsed. Jason recommended replacing the stack and the bottom (beneath the floor) with a plastic pipe. The job was finished in one day and the fellows did a great job of cleaning up. That was 6 months ago and I haven’t had a problem since. I would definitely recommend this company.
