How much does it cost to unclog a main sewer line professionally?

The cost to unclog a main sewer line is confirmed after a technician diagnoses the blockage on site. Pricing depends on access, blockage type (roots, grease, debris), and method used (rooter vs. hydro‑jetting). We start with a camera inspection to pinpoint the issue, then clear the line and advise on repairs if needed. Savings are available: $43 off sewer and drain cleaning, free camera inspection for A‑List members (regular price $489), $200 off sewer repair with excavation, and $150 off outside clean‑out installation. Serving Seattle and Everett.
