I had very good experience with this company. We had a major sewer malfunction and backup late evening on a Saturday. I called several 24 hr plumber services and Jim Dandy was the most responsive - able to come within 1 hour. They discovered a serious breach in our main sewer line and sent a team on a Sunday morning to dig and repair it. Very impressed with the prompt response, the people involved and the work done. It was expensive but done well and saved us quickly.
