This company did a partial replacement of a drain line and said everything else was fine. When problems occured again, they said that the other part of the line needed replaced. What a scam. It would have been less expensive to do it all at once and they offered no discount for the later work. To top it off, they still haven't repaired the lawn as promised and always have an excuse. This is nonsense. Save yourself the trouble and just get another company to do your work.
