How Much Does Drain Cleaning Cost in Southern California?

A clogged drain is a common plumbing problem. Water is backing up in your sink, shower, or toilet, and you want it cleared.

What it costs depends on where the clog is, how severe it is, and what method the plumber uses. The figures below are typical estimated ranges for licensed plumbers in LA and Orange County. They are not quotes.

Typical Drain Cleaning Costs

Service	Typical estimated range
Snaking one sink, tub, or shower drain	$100 to $250
Clearing a deep toilet clog (closet auger or power snake)	$150 to $350
Snaking the main sewer line (cleanout to street)	$200 to $450
Hydro jetting a residential line (up to 4 inch pipe)	$350 to $600
Hydro jetting the full main sewer line, house to street	$500 to $900
Sewer camera inspection	$150 to $350
Spot repair of a damaged sewer section (5 to 10 feet)	$1,500 to $4,000

After-hours drain clearing typically adds $75 to $150. Some plumbers charge a flat rate and others charge by the hour plus parts, so get the price in writing before work begins. For bigger jobs such as a sewer repair, the Contractors State License Board (CSLB) recommends getting at least three bids and checking the contractor's license (CSLB).

Why Drain Cleaning Costs Vary

Location of the clog. A clog close to a sink or tub is quicker to reach than one deep in the main line toward the street. The farther the cable or hose has to travel, the longer the job takes. Type of clog. Hair and soap buildup clears quickly. Tree roots, hardened grease, or mineral scale take longer and may need different equipment. Access. An easy-to-reach cleanout keeps labor time down. A cleanout buried under landscaping or concrete, or a home without one, adds time and cost. Recurring clogs. If the same drain keeps clogging, a camera inspection can show whether a crushed pipe, a sag, or roots are the cause. Those problems need a repair, not just another cleaning.

Snaking vs Hydro Jetting

Plumbing snake (auger). The plumber feeds a rotating cable down the drain. The head grabs the clog or breaks it apart so the debris can flow away. Typical estimated range: $100 to $250 for one fixture drain and $200 to $450 for the main sewer line.

Snaking works well for hair, soap buildup, and minor blockages. It opens a path through the clog but does not scour the pipe walls. With a root-cutting attachment, a cable machine can also cut through roots (PHCP Pros).

Hydro jetting. The plumber sends high-pressure water through the line to clear grease, scale, and roots and flush the debris out. Typical estimated range: $350 to $600 for a residential line and $500 to $900 for the full main line from house to street.

Neither method fixes a broken pipe. Roots get into laterals through cracks and breaks (H2OC), so if the pipe is damaged, cleaning only buys time until the section is repaired.

When to Try DIY and When to Call a Plumber

Try DIY first if only one fixture is slow and the water still drains. You can try:

• A plunger
• A hand drain snake from a hardware store

Skip the old tip of chasing grease with hot water. LA County Public Works says running hot water does not stop grease from hardening and building up inside the pipes (LA County Public Works).

Call a plumber if more than one fixture backs up at the same time, using one fixture makes another back up, drains keep getting slower, sewage comes up through a floor drain or tub, or you notice sewage odors or soggy ground over the sewer line outside. Sewer agencies list these as signs of a sewer line blockage rather than a single clogged drain (Aspen Consolidated Sanitation District, H2OC). If sewage is already coming into the house, start with what to do when your sewer backs up.

Main Sewer Line Clogs

If several drains back up at once, the clog is likely in the main line, the pipe (called the lateral) that carries everything from your house to the public sewer.

Common causes. In the City of Los Angeles, LA Sanitation says tree roots and poured fats, oils, and grease cause more than half of sewer backups (LA Sanitation). Wipes and other items that do not break down, and pipes that have sagged or collapsed, also cause main line clogs. Repair cost. If the camera shows damage, a spot repair of a 5 to 10 foot section typically runs $1,500 to $4,000, and replacing the whole lateral typically runs $5,000 to $15,000. Sewer line replacement requires a city permit and inspection. Torrance's lateral policy, for example, lists a plumbing permit for the private side and a separate permit for work in the public right-of-way (City of Torrance). Prevention. Orange County's property owner guide to sewer laterals recommends periodic cleaning to remove grease, debris, and roots, and not planting trees or large shrubs above or within several feet of your lateral (H2OC).

Camera Inspection

A small waterproof camera goes down the line and shows what is causing the problem and where. Typical estimated range: $150 to $350. It is most useful when clogs keep coming back: a collapsed or badly broken line needs a repair or replacement, while roots or buildup in a sound pipe may only need cleaning.

How to Reduce Drain Clogs

• Do not pour fats, oils, or grease down the drain. Let grease cool, then put it in the trash.
• Use a drain screen to catch food scraps and hair.
• Use the garbage disposal sparingly, and keep coffee grounds and eggshells out of it (LA County Public Works).
• Flush only toilet paper. Wipes, even ones labeled "flushable," do not break down and can clog pipes (San Bernardino County Special Districts).
• If roots keep returning in an old lateral, ask about repairing or replacing the damaged section.
• If any drain in your home sits lower than the cover of the next upstream public sewer manhole, the California Plumbing Code requires a backwater valve to keep sewage from flowing back in (LA County Sanitation Districts).
