A sewer backup is a health hazard. Keep people and pets away from affected areas, don't run water or flush, and call us immediately. We clear the blockage, identify the cause (roots, grease, collapsed pipe, city main issues) and get your drains flowing.
After clearing, we can camera the line to prevent a repeat and advise on backwater valves that protect basements from municipal surges.
