We were having a sewer back-up problem and were referred to Super Rooter. Super Rooter came in quickly and initially tried snaking the line to clear out the blockage, but could not pass by the building trap just outside of the house (identified for old Toronto homes with an old cast iron breather pipe coming out of the ground with a mushroom shaped cap). Jerry came in, camera inspected the line and assessed the issue to be the building trap. We negotiated a fair price for the work and the Super Rooter crew started digging to replace the building trap with a back-to-back clean out later that morning. The work took about 5 hours to complete. The crew was great at explaining and keeping me informed during the work. After the work was done, Jerry came by and inspected the work with his camera, identified some root intrusion down the line and sent his service crew in for a no charge preventative snaking maintenance. He also identified a minor blockage with his camera on a City owned section of pipe which we ended up calling 311 to deal with. I would highly recommend Super Rooter's services to others.
