Repeated backups or several slow fixtures warrant an investigation beyond the nearest drain. Ask whether the suspected problem is in the building plumbing, the private sewer lateral, or the public main. The answer determines who should respond and which repairs are actually yours to authorize.
Get Evidence Before Choosing a Method
Request a camera recording where appropriate, an explanation of its limitations, and a marked location of the defect. A line may need clearing before a useful inspection is possible. Ask the provider to distinguish obstruction, roots, damaged joints, and collapse. Keep occupants away from sewage and arrange qualified cleanup when needed.
Compare Repair Alternatives
Ask why clearing, a localized repair, lining, or replacement fits the documented condition. A trenchless proposal still needs an explanation of access points and any excavation. Compare the same length and endpoints across bids, including permits, traffic arrangements, utility coordination, connections, testing, and restoration of paving or landscaping.
- Will I receive the video and a written interpretation?
- What condition would make the proposed method unsuitable?
- Who restores the driveway, sidewalk, and planting areas?
Establish Responsibility Before Excavation
Ask the sewer utility to identify the service boundary and the process for reporting a suspected public-system problem. Do not assume that responsibility ends at the curb or property line everywhere. Show the contractor any easements, previous repairs, roots, or recurring wet-weather backups. Compare how each repair method affects driveways, sidewalks, traffic, and neighboring access. Contact 811 before excavation and follow the applicable notification and marking process. Confirm who obtains street-opening or other local approvals, coordinates private utility locating if needed, and restores each disturbed surface after inspection.
Questions Homeowners Ask
Is recurring root removal a permanent repair?
Ask what allows roots to enter and whether the underlying condition remains. Clearing and pipe rehabilitation solve different problems, so compare ongoing maintenance with a documented repair option.
Should I call the utility first?
If several properties are affected or a public-main problem is suspected, contact the utility promptly. It can explain its response process and the boundary of owner responsibility.
