Arrived within 2 hours of my call. I had reported that the main line needed cleaned out, and that two sink drains were draining slow. Did a main line cleanout and that fixed the basement sink issue. The upstairs drain was still gurgling but he explained it was due to the accordion connection that had been used and that there was no back up. It would have been easy for them to tell me the sink drains needed scoped, but they didn't..I appreciate their honesty.
