Gateway Rooter is the leading choice of San Francisco realtors who specialize in historical homes and homes located in highly dense neighborhoods. Unfortunately, San Francisco homes suffer the most sewer related blockages due to aging sewer pipes and mature trees. Many newly renovated (fliped) homes appear beautiful on the exterior, but commonly suffer municipal sewer blockages that are hidden nine feet below the sidewalk or street surface. Since maintenance of aging sewer pipes is no longer cost effective, replacement becomes necessary.
