About Us

Main Sewer Line Cleaning Across California

California Drain Cleaning is a main sewer line specialist. We work on the lateral that runs from your building to the city connection, and we do not take on general plumbing. Our office is at 3274 E Guasti Rd Ste 100 in Ontario, and we have local crews in each of the 100 California cities we serve, from San Diego County through Orange County, Los Angeles and the Inland Empire to the Bay Area, the Central Valley, the Central Coast and Chico.

We are open 24 hours a day, 7 days a week. A blocked main line is not a problem that waits politely until business hours, and a backup that goes four hours before anyone arrives is usually the difference between a mopped floor and replaced flooring. Overnight, weekend and holiday calls get the same response as a Tuesday morning.

  • Main sewer laterals only — we are not general plumbers

  • Local crews in each of the 100 California cities we serve
  • Every line camera-surveyed before anyone quotes a repair

Why Choose California Drain Cleaning

We do one thing: the main sewer lateral running from your building to the city connection. That focus is why we camera every line before quoting it, and why we can tell you what your pipe is made of and what that rules in or out.

✦

Open 24 Hours, Every Day

Sewer lines back up at two in the morning as readily as at two in the afternoon. We answer and dispatch at any hour, any day, including holidays.

✦

Local Crews in 100 Cities

Crews across the state, from San Diego County through the Inland Empire and Los Angeles to the Bay Area, the Central Valley and up to Chico. Response does not depend on your distance from one office.

✦

We Look Before We Quote

California laterals run clay, cast iron, Orangeburg and ABS depending on the decade a street was built. Each fails differently and each rules certain repairs out. We identify the material on camera before anyone quotes.

✦

You See What We See

You get the footage, a written list of defects by distance down the line, and a straight answer on what needs doing now versus what can wait.

How · it · works

How a California sewer line job runs, start to finish

1

Call Any Time, Day or Night

Describe what is happening and we will tell you what to do immediately, which on an active backup is to stop all water use in the building. We quote the callout before dispatching, and overnight and weekend calls are handled the same as weekday ones.

2

Camera the Line, Not Just the Blockage

A push camera surveys the whole lateral to the city connection, with a sonde locator marking any defect for position and depth. We identify the pipe material, which is the fact that governs everything that follows.

3

Clear It With the Right Method

Cable for a simple clearance, hydro jetting to restore full bore, cutter heads for root mass, chain knockers for cast iron scale. Sound clay takes jetting; Orangeburg never does. Matching method to material is the whole job.

4

Verify and Explain

A second camera pass shows the restored bore and anything structural the blockage was hiding. You get the footage, the written findings, and an honest view on whether this was a one-off or a pattern worth repairing.

Testimonials

What CA Customers Say

“My kitchen sink backed up with greasy water after cooking for a family dinner, and nothing I tried worked. California Drain Cleaning sent a tech who scoped the line and ran a powered auger through the main to break up the grease buildup. Water now drains right away without any gurgling.”
MG Maria G.Ontario, CA
“The shower in my master bath was draining slow from hair and soap scum, leaving standing water after every use. They used hydro jetting on the branch line to clear it out completely. The flow is strong again and the floor stays dry.”
JP James P.Ontario, CA
“Tree roots had invaded the main sewer line near my backyard, causing the toilet to bubble and the laundry sink to overflow. The crew located the blockage with a camera, cut the roots, and flushed the line. Everything works normally now with no recurring clogs.”
ER Elena R.Ontario, CA

Main Sewer Line Cleaning FAQs — California

Still have questions? We're happy to talk it through.

(866) 811-8305
+ How much does main sewer line cleaning cost in California?
A straightforward cable clearance from an accessible cleanout typically runs $150 to $350, hydro jetting $400 to $750, and a camera survey $175 to $350. Cast iron descaling and commercial work are considerably more. Costs run higher in the Bay Area and coastal cities than in the Central Valley, and city permit requirements vary. We quote in writing before starting.
+ How do I know if it is my main line or just one fixture?
If more than one fixture is affected, or if water comes up somewhere when you run water somewhere else, it is the main lateral. A single slow sink is a branch problem. In a slab-on-grade home the main line usually shows itself in a ground-floor shower or tub, because that drain sits lowest.
+ Sewage is backing up right now. What should I do first?
Stop using water everywhere in the building, including washing machines and dishwashers, and stop flushing. Every gallon added has to surface somewhere inside. Keep people and pets clear, and stay away from it if it has reached electrical equipment. Then call (866) 811-8305.
+ Do I need a sewer lateral compliance certificate to sell my house?
In the East Bay you may. Oakland, Berkeley, Alameda, Albany, Emeryville, Piedmont, El Cerrito and Kensington operate under a regional private sewer lateral ordinance requiring a certificate showing the lateral is leak-free before many sales and remodels can close, and Berkeley runs its own programme as well. We survey the line first so you know whether it will pass before you pay for a test.
+ Which trees cause the most sewer trouble in California?
The Indian laurel fig, planted as a street and parkway tree across Los Angeles and much of Southern California, is the most aggressive root intruder we see. Eucalyptus is close behind and found statewide. California pepper, liquidambar, jacaranda, magnolia and willow all appear regularly in our footage.
+ Can hydro jetting damage an older pipe?
Sound clay and cast iron take jetting at appropriate pressure, and most California laterals are one or the other. Orangeburg fibre conduit, used widely in the postwar tract years, must never be jetted because it has usually already lost wall section. That is why we camera first rather than after.
+ Why does my line keep blocking in the same place?
Because clearing removes the blockage but not the reason for it. In California the usual causes are a belly where the ground settled under the pipe and it lost grade, an offset joint from soil movement or ground motion, or roots at a joint. A camera survey identifies which, and often a short spot repair ends the cycle for good.
+ Do you serve my city?
We cover 100 California cities, from San Diego and Orange County through Los Angeles, the Inland Empire and the Coachella Valley to the Bay Area, Central Valley, Central Coast and Chico. Check the service area list or call (866) 811-8305 and we will tell you straight away.
