Sewer Line Repair in Van Nuys and the San Fernando Valley
A backed-up sewer line tells you something failed. It does not tell you where, or why. PowerRoute runs a camera through the line, locates the damage from the surface, and shows you the video before anyone quotes a fix. You choose between a spot repair, a liner, or a full replacement with the footage in front of you.
No obligations. Honest pricing from licensed plumbers.
Sewer Line Repair From a Van Nuys Crew
Sewer line repair covers everything on the run from your house to the city main: clearing the blockage, finding the failure with a camera, fixing one bad section, lining a worn pipe from the inside, or replacing the line end to end. The right answer depends on what the video shows, so every job starts there.
Many Valley homes went up in the postwar decades, and laterals from that era are often vitrified clay or cast iron. Clay joints let roots in. Cast iron corrodes from the inside. Both fail in ways a camera picks up long before the yard turns soggy. A soggy yard with drains running fine often points to the pressurized supply side instead. Our water line repair page covers those leaks.

Signs Your Sewer Line Is Failing
One slow sink is a drain problem. A sewer line problem shows up across the house, because every fixture empties into the same pipe. If you see two or more of the signs below, the main line is the likely cause.
Several Drains Back Up at Once
Flushing a toilet pushes water up into the tub or shower. The lowest fixtures in the house overflow first because the main is full.
Gurgling Toilets and Tubs
Air trapped behind a partial blockage escapes through the nearest fixture. Gurgling after the washer drains or a toilet flushes points to the main, not one trap.
Sewer Odor Inside or Out
A cracked lateral or a broken cleanout lets sewer gas escape. You smell it near floor drains, in the yard, or along the side of the house.
Wet, Sunken, or Extra-Green Lawn
Sewage leaking from a broken line feeds the grass above it and softens the soil. A soggy strip or a dip that follows the line toward the street is a classic sign.
One Drain or the Whole House? Count the Fixtures
One slow sink or tub is usually a clog in that drain, so start with drain cleaning. Several drains backing up together, or water rising in the tub when you flush, point to the main sewer line.
Sewer Camera Inspection: What the Video Shows
We feed a waterproof camera through a cleanout and record the full run of the lateral. A transmitter in the camera head lets us locate each defect from the surface, with depth, so the repair plan points to a spot in your yard instead of a guess. You get the video and a written summary. If the line is packed with grease or roots, we clear it first with hydro jetting so the camera sees pipe wall, not debris.
Root Intrusion
Roots enter through clay joints and cracks, then grow into a mat that catches paper and grease. The video shows how many joints are affected and where.
Cracks and Breaks
Cracks, fractured sections, and holes show as soil or daylight through the pipe wall. One break can mean a spot repair. Breaks every few feet mean the pipe is done.
Offset and Separated Joints
Ground movement shifts pipe sections out of line. An offset joint leaves a lip that snags waste, and a separated joint leaks into the soil.
Bellies and Sags
A low section holds standing water and solids. The camera shows water pooling where the pipe should drain, and the locator shows how long the sag runs.
Why Sewer Lines Fail in Valley Homes
Most failures trace back to pipe material, tree roots, or ground movement. The cause matters, because a line that failed from roots needs a different fix than one corroding from the inside.
Clay Pipe and Tree Roots
Vitrified clay laterals use short sections with many joints. Mature street trees and yard trees find those joints and grow into them.
Cast Iron Corrosion
Cast iron rusts from the inside. Scale narrows the pipe, catches waste, and in time opens holes along the bottom of the line.
Ground Movement
The Valley took the 1994 Northridge earthquake hard, and rigid clay and cast iron do not flex. Shifted joints and cracks from movement often stay hidden until a camera finds them.
Grease, Wipes, and Buildup
Grease hardens on the pipe wall, and wipes sold as flushable do not break down. Both build blockages that put pressure on weak joints.
Who Owns Your Sewer Line, and What Repair Covers
The pipe that carries waste from your house to the city main is the sewer lateral. In the City of Los Angeles, which includes Van Nuys and most of the Valley, that pipe belongs to you. LA Sanitation puts the full lateral on the property owner, from the building to the connection at the street main. When it cracks, fills with roots, or sags, the repair is yours, even where the pipe runs under the sidewalk.
Spot Repair
One cracked, broken, or offset section in a pipe that is otherwise sound. We expose and replace that section only.
Pipe Lining
Cracks or root entry along the length, but the pipe still holds its shape. A resin liner cured inside the old pipe seals it without digging up the run.
Full Replacement
Collapsed pipe, repeated breaks, or long bellies. We replace the lateral end to end, by open trench or trenchless method, with new pipe and a cleanout.
Repair or Full Replacement: How We Decide
We base the recommendation on the video, the pipe material, and the age of the line. One defect in an otherwise sound pipe gets a repair. Defects along the full run get a replacement, because patching one break in a failing pipe moves the next backup a few feet down the line.
Clean, Repair or Line
- Roots or grease with no structural damage. We clear the line with hydro jetting and set a schedule to check it again
- One cracked, broken, or offset section
- The rest of the pipe is sound
- Cracks or root entry along the length, but the pipe still holds its shape
Replace the Whole Line
- The pipe has collapsed
- Breaks show up every few feet
- A long belly holds standing water and solids
- Defects run the full length, so one patch moves the next backup a few feet down the line
Trenchless vs. Digging: Which Fits Your Line
Trenchless replacement pulls new pipe through the path of the old one, or lines the old pipe from inside, through one or two small access pits. It spares driveways, hardscape, and mature landscaping. Open trench replacement digs along the line and lays new pipe in the trench.
Digging still makes sense for a short run in open soil, a single spot repair, a deep belly that has to be regraded, or a pipe so collapsed nothing passes through it. Trenchless wins when the line runs under concrete, a driveway, or landscaping you want to keep. We name the method after the camera inspection, and we quote both when both work.

What Affects Sewer Line Repair Cost
We price after the camera inspection, because the same backup can come from a root clog or a collapsed pipe, and those are two different jobs. Four things move the number most.
Repair Method
Cleaning, a spot repair, lining, and full replacement sit on different price scales. The camera decides which one applies.
Length and Depth
Laterals are priced by the foot. Longer runs and deeper pipe take more material, more digging, and more time.
What Sits Above the Line
Concrete, driveways, and hardscape add breaking and restoration cost to an open trench, which often makes trenchless the cheaper path.
Street Work and Permits
Repairs that reach the sidewalk or street need a city S-Permit and a bonded sewer contractor, plus traffic control and pavement repair.
What Homeowners Typically Pay
National cost guides from HomeGuide and Angi published for 2026 put a sewer camera inspection at about $100 to $500 and a single cracked-section repair at roughly $600 to $1,050. Full sewer line replacement runs about $50 to $250 per linear foot, with trenchless pipe bursting at roughly $60 to $200 per foot and pipe lining at $90 to $250 per foot. HomeGuide puts a typical 40-foot replacement between $2,000 and $10,000. Where the pipe runs under a concrete slab, Angi puts the cost of the affected section at up to $300 to $350 per linear foot, with slab access and restoration included. That figure covers the slab section itself. It is not a charge added on top of the per-foot replacement rate.
Los Angeles labor rates land at the high end of national ranges, and permit and street restoration costs add to any job that reaches the city main. Treat these numbers as context for reading an estimate, not a price for your line. Your quote comes after we see the pipe.
Sewer Line Permits in Van Nuys and the City of Los Angeles
Van Nuys is part of the City of Los Angeles, so sewer work here runs through city permits and inspection. Which permit applies depends on where the work happens along the line. We pull the right ones and schedule the inspections as part of the job.
LADBS Plumbing Permit
Repair or replacement of the building sewer on your property falls under a plumbing permit from the Los Angeles Department of Building and Safety, inspected before the trench is closed.
Bureau of Engineering S-Permit
Work on the house connection lateral from the property line out to the main uses an S-Permit, issued by the LA Bureau of Engineering.
Bonded Sewer Contractor for Street Work
Any digging in the public right of way, such as the parkway, sidewalk, or street, requires a Bonded Sewer Contractor to hold the S-Permit.
Outside City Limits
Burbank, San Fernando, and unincorporated areas run their own permit offices. We confirm the agency by address before we schedule.

Sewer Line Repair FAQs
Common questions about sewer backups, camera inspections, repair options, and permits in Van Nuys and the San Fernando Valley.
Count the fixtures. One slow sink or tub is usually a clog in that drain. Several drains backing up together, water rising in the tub when you flush, or gurgling across the house point to the main sewer line. A camera inspection confirms it.
The property owner. In the City of Los Angeles, the owner is responsible for the entire sewer lateral, from the house to the connection at the city main, including the section under the sidewalk and street. The city maintains the main.
It shows the inside of the pipe: roots, cracks, breaks, offset joints, sags, and buildup. A transmitter in the camera head lets us mark the depth and position of each defect from the surface. You get the recorded video.
Yes, when the damage is limited. One broken or offset section in a sound pipe gets a spot repair. A pipe with cracks along its length that still holds its shape is often a candidate for lining. Replacement fits when the camera shows breaks, collapse, or sags along the full run.
No. Trenchless spares driveways, concrete, and landscaping, and it often finishes faster. Digging is still the better fit for a short run in open soil, a single spot repair, or a sagging line that has to be regraded. We recommend the method after the camera inspection.
It depends on the repair method, the length and depth of the line, and what sits above it. National 2026 cost guides put a single-section repair at roughly $600 to $1,050 and full replacement at about $50 to $250 per linear foot. Your quote comes after the camera inspection.
Yes. Sewer repair and replacement on private property needs a plumbing permit from LADBS. Work on the lateral from the property line to the main needs an S-Permit from the Bureau of Engineering, and work in the public right of way requires a bonded sewer contractor. We handle the permits and inspections.
A spot repair or a lining job often wraps up in a day. Full replacement takes longer, depending on the length of the line, the method, and permit and inspection scheduling. You get a timeline along with the written options.
