Main sewer line clog cost in the US.
A cable machine or jetter run through a cleanout to open the main drain leaving the house. Almost pure labour and equipment time — there is no part.
The same wrench costs different money in different places, because the hand holding it does. Pick your city for the local band, the upsells and the script.
- 01Stop using every drain in the house, including toilets and the washing machine.
- 02Find the cleanout — a capped pipe outside near the foundation. Its presence cuts the labour.
- 03If sewage has come up into the house, stop here. That is a containment problem, not a pricing one.
Pro. A rented drum machine can break off in the line and turn a $475 job into an excavation.
- Escalating from a snake to a full line replacement on the same visit — one documented case fell from a $9,000 proposal to $5,000 of necessary work after a second opinion.
- A camera inspection billed separately after you already paid for the clear, when many shops include it.
- Hydro-jetting sold as mandatory when a cable already opened the line.
Root intrusion, no cleanout, or per-foot pricing (up to $310/ft in some markets) pushes severe jobs to $4,500. That is a repair, not a clear, and should be quoted as one.
National band from published US cost guides, 2026 editions. Adjusted for this metro by scaling only the labour share of the job by the metro's median plumber wage against the national median of $34.70/hr (BLS OEWS, May 2025). Parts are not scaled.
Comparable quotes from this metro in our Price book: 0. This band is derived from national guides and local wage data, not from local quotes. We will say so on this page until it is not true.
If you think a figure here is wrong, write to pricebook@getitplumming.com with the quote. Corrections go into the next edition and we do not argue with an invoice.
Angi and HomeGuide both put a main-line clog at $350–$600 typical, from $100 for a simple snake at an accessible cleanout.
