In many cases, modern repair methods allow sewer lines to be repaired or replaced with less impact to yards, driveways, and foundations, followed by proper restoration. 

The goal is to clearly identify the problem, explain the available options, and help homeowners move forward with confidence. Available in the greater Portland metropolitan area.
