No Damage to Landscape, Interior, or Exterior of Structures. Before trenchless sewer repair, there would have been a team of people at your home or business digging a trench to uncover the area of broken pipe, or jackhammering their way through your bathroom floor. After repairing the problem that same team would fill up the trench and try to put things back in order. That’s an extremely time consuming process and you know you will be billed for all that time.
