Rooter service costs can vary a lot depending on the plumber and the severity of the clog, so we put together this guide to help you understand what you’re paying for and what a fair price looks like in the San Gabriel Valley and greater Los Angeles area.
What is rooter service?
Do you have a tree in your yard, or does your neighbor? If so, your sewer line is at risk of root intrusion. Tree roots can grow into and block a sewer line, causing sewage to back up into your home through toilets, showers, and sinks.
Rooter service clears tree roots and other debris from a sewer line using a motorized rooter machine that spins a cutting blade or auger at high speed, clearing the obstruction without damaging the pipe.
Why do tree roots invade sewer pipes?
Roots grow toward water, nitrogen, and other nutrients — all of which are abundant inside a sewer line. Over time, as roots grow larger, they can crack and work their way through the pipe, especially in older or narrower lines.
If your home was built before 1960 and there’s no record of sewer pipe replacement, there’s a good chance your line is clay or Orangeburg pipe — both are especially vulnerable to root intrusion. Clay cracks under root pressure over time, and Orangeburg (a paper-pulp composite popular mid-century) breaks down and leaves gaps roots can exploit.
Why tree roots are a problem
- Sewage backing up into the home through toilets, showers, and sinks — if you’re dealing with a clogged sewer line, root intrusion is one of the most common causes.
- Extensive damage to the sewer line over time.
- Costly repairs once the damage becomes structural rather than a simple clog.
How do you remove roots from sewer pipes?
There are two options: replace the damaged section of pipe, or clear the roots out with a rooter machine.
Replacement is the more expensive route, typically requiring excavation — though many jobs can now be done without digging up the yard using trenchless sewer repair. This is usually only necessary when root damage is extensive or the blockage is too severe for a rooter to clear.
Using a rooter machine is the less expensive option and is often just as effective for moderate intrusion. Rooters have been clearing tree roots from sewer pipes since the early 1900s, though they’re not 100% effective in every case.
What should you expect to pay?
Rooter service typically runs $100–$1,000, depending on the severity of the root intrusion and pipe access. If excavation and pipe replacement is required instead, costs can run $5,000 or more. For a full breakdown, see our pricing page or ask about financing options for larger jobs.
Who should you call?
Rooter service should only be performed by a licensed plumber, since improper use of a rooter machine can damage the pipe. If you suspect a root blockage, the first step is a professional assessment — often with a sewer video camera inspection to confirm what’s actually going on before recommending a fix.
