Main Sewer Line Clog Cost Estimator — Snake vs Hydro Jetting
Clearing a main sewer line runs anywhere from $100 for a straightforward snaking to $1,400+ for hydro jetting a root-choked, grease-lined pipe. The spread comes down to three things: how bad the clog is, whether roots are involved, and how the pro gets into the line.
Set the details below for an honest range. If sewage is backing up right now, stop running water first — every flush adds to what's coming back.
How this works
This estimate uses 2026 national pricing published by Angi, HomeAdvisor, and HomeGuide: snaking a main line runs $100–$500 with the average clog repair around $380; hydro jetting runs $350–$1,400 with typical jobs at $350–$600; root cutting adds $100–$600; and a camera inspection adds $125–$500. Severe jobs that combine jetting with a camera can reach $1,600. The estimator picks the service the inputs point to — a first-time clog gets snake pricing, while recurring clogs or suspected roots get jetting pricing — and stacks the add-ons you select.
The snake-versus-jet logic mirrors what honest drain pros tell customers: a snake punches a hole through the blockage, which restores flow cheaply but leaves the pipe walls coated, so grease and roots close back in — roots especially regrow quickly through a snaked hole. Hydro jetting scours the full pipe diameter and keeps roots out for roughly 2–3 years, which is why it wins on cost-per-year for recurring problems despite the higher ticket. Access matters too: with no cleanout, the pro pulls a toilet or runs from a roof vent, and that extra labor shows up on the bill (camera scopes, as a benchmark, run $175–$750 without a cleanout versus $125–$500 with one).
One thing this tool won't do is pretend a clearing is always the end of the story. A main line that keeps clogging usually has a physical cause — root intrusion, a belly, or a break — and clearing it treats the symptom. That's why recurring-clog results here recommend the camera add-on: $125–$500 of footage tells you whether you're done or whether a repair conversation is next.

Frequently Asked Questions
How much does it cost to unclog a main sewer line?
Snaking runs $100–$500, with the national average clog repair around $380. Hydro jetting — for severe, greasy, or root-infested lines — runs $350–$1,400 (typically $350–$600). Root cutting adds $100–$600 and a camera inspection adds $125–$500, so a worst-case severe clog with jetting and camera can reach about $1,600.
Is hydro jetting worth it over snaking?
For a first-time, one-off clog, no — a $100–$500 snaking usually does the job. For recurring clogs or roots, usually yes: a snake cuts a hole through the blockage and the problem regrows, while jetting scours the full pipe wall and keeps roots out for 2–3 years. Paying $350–$600 once often beats paying for a snake visit every few months.
Why does not having a cleanout cost more?
Without a cleanout, the pro has to reach the main line by pulling and resetting a toilet or working from a roof vent — extra labor on every visit. As a benchmark, camera inspections run $175–$750 without a cleanout versus $125–$500 with one. If your line needs regular attention, having a cleanout installed pays for itself quickly.
Will a clog come back after it's cleared?
It depends on the cause. A one-off obstruction, cleared, is gone. But roots regrow — quickly after snaking, in roughly 2–3 years after jetting — and a belly or break in the pipe will keep collecting waste no matter how it's cleared. If your main line has clogged more than once, a camera inspection ($125–$500) is the honest next step: it shows whether you need maintenance or a repair.
