My main sewer line was overflowing, and so I called Ducky's because I had seen good reviews online. They were quick to get back to me, and I was able to book an appointment quickly. When Andy came over, he found a clay blockage that he thought might be a broken sewer main pipe, and suggested we call the city to see if the break was in their section of pipe. Even though his job was done and paid for, Andy called a couple days later to check in on me, and see how everything had gone. The city had given a different diagnosis than what Andy thought, so he volunteered to come back on his own time to do a video review and make sure nothing was missed. I was very impressed with his follow through, and willingness to make sure that we had all the information needed about the line. He was very knowledgeable and pleasant to work with, and I would definitely use Ducky's again.
