When your sewer line needs repair, the method you choose affects your yard, your driveway, your wallet, and your schedule. This guide explains both options clearly so you can make an informed decision before any work begins.
Most homeowners don't realize there's an alternative to tearing up their yard.
A failing sewer line is one of the more serious problems a homeowner can face. Left unaddressed, a cracked or root-invaded pipe causes sewage backup, foundation damage, and serious health hazards. The repair has to happen — but the method matters enormously.
For decades, dig-and-replace was the only option. Crews would excavate a trench from your home to the street, pull out the old pipe, lay new pipe, and refill the trench — destroying whatever sat above it in the process. Landscaping, concrete, driveways, garden beds: all of it gone.
Trenchless sewer repair changed that equation. Modern cured-in-place pipe (CIPP) lining and pipe bursting techniques can restore a failing sewer line with minimal excavation — often a single day's work, with your yard left intact. This guide breaks down both methods: how they work, what they cost, how long they take, and which one fits your situation.
The excavation approach has been the industry standard for generations — and it shows.
Traditional sewer repair begins with locating the failed section of pipe and digging a trench from the access point to the problem area — often the full length of the lateral from your house to the city main. In Los Angeles, these laterals commonly run 50 to 100 feet or more, and they frequently pass under driveways, mature landscaping, concrete pathways, or decorative hardscape.
Once exposed, the crew removes the damaged pipe and lays new PVC in its place. The trench is backfilled in layers and compacted. Any concrete or pavement cut to gain access must be broken out and repoured after the fact. Landscaping removed is gone permanently unless you replant.
Typical cost: $8,000–$25,000 depending on length, depth, and what's above the pipe. Replacing a Beverly Hills driveway alone can add $10,000–$20,000 on top of the plumbing cost.
Typical timeline: 3–7 days for excavation, pipe work, backfill, and preliminary surface restoration. Concrete repour and final landscaping may extend this by weeks.
Warranty: Varies by contractor. Standard industry warranty on materials and labor is typically 1–5 years.
A rehabilitated pipe — installed from the inside, with your yard untouched.
Cured-in-place pipe lining (CIPP) is the primary trenchless method for sewer line rehabilitation. The process starts with a high-definition camera inspection to map the inside of your existing pipe — identifying cracks, root intrusion, joint offsets, and deterioration. This inspection determines whether the pipe is a candidate for lining.
If approved, a flexible liner saturated with epoxy resin is inserted into the existing pipe through an existing cleanout or a small access point — typically a single excavation no larger than 18 inches by 18 inches. The liner is inflated against the interior walls of the old pipe and held in place while the resin cures, forming a seamless, jointless new pipe inside the old one. Root intrusion points, cracks, and minor joint gaps are all sealed in the process.
An alternative trenchless method, pipe bursting, is used when the existing pipe is too degraded to line. A bursting head is pulled through the old pipe, fragmenting it outward while simultaneously pulling a new pipe into position. Both methods require minimal surface disturbance.
Typical cost: $3,000–$15,000 depending on pipe length, diameter, and access conditions. Savings over traditional excavation are often significant once landscaping and concrete restoration costs are accounted for.
Timeline: Most trenchless projects are completed in a single day. You have a functioning sewer line the same evening.
Pipe life: CIPP liners carry a 50-year rated service life. The seamless epoxy interior also resists root re-intrusion far more effectively than jointed pipe.
Atlas warranty: 25 years on all Atlas trenchless CIPP installations.
A direct comparison of the two most common sewer repair methods.
| Factor | Traditional Excavation | Trenchless CIPP |
|---|---|---|
| Cost | $8,000–$25,000 | $3,000–$15,000 |
| Timeline | 3–7 days | 1 day |
| Landscape damage | Significant | None |
| Concrete broken | Yes | Minimal |
| Pipe lifespan | Varies | 50 years |
| Warranty | Varies | 25 years (Atlas) |
The right approach depends on the condition of your existing pipe, what's above it, and how you're accessing it.
Free sewer camera inspection determines which method is viable for your property.
No homeowner should commit to either approach without first seeing what's inside the pipe. Atlas Home Pro's camera inspection gives you a full video record of your sewer line's condition — and a clear recommendation on the repair path before any work begins. There's no charge for the inspection.
Beverly Hills and Bel Air present a specific set of circumstances that make trenchless sewer repair far more practical than the alternative. Both neighborhoods are defined by mature, established landscaping — coast live oaks, ficus hedges, Italian cypress, and decades-old ornamental gardens that took years and significant investment to cultivate. Excavation doesn't just damage these landscapes temporarily; it removes them.
Long sewer laterals are also common in these neighborhoods. A property on Benedict Canyon Drive or in the hills above Sunset Boulevard may have a lateral that runs 80–120 feet before reaching the street main — all of it potentially passing under a circular driveway, stone walkway, or specimen tree root system. Breaking open that length of concrete and hardscape for traditional excavation, then restoring it to estate-level quality, can cost more than the plumbing repair itself.
Trenchless CIPP eliminates that calculation entirely. The same lateral is relined from a single access point, the hardscape stays intact, the trees stay rooted, and the project is finished the same day it starts. For homeowners in Beverly Hills, Bel Air, Brentwood, and similar neighborhoods, the trenchless premium — when it even exists — is routinely outweighed by what it avoids.
