Sewer Line Repair & Replacement Cost in Santa Clarita, CA

Sewer camera inspection

$150 - $350

A video camera run through the sewer line to identify the exact problem and location. This is step one before any repair. The footage helps the plumber give you an accurate quote and shows you exactly what is going on.

Trenchless sewer lining (CIPP)

$4,000 - $8,000

A resin-coated liner is inserted into the existing pipe and inflated, creating a new pipe inside the old one. No digging required. Works well for cracked or root-damaged pipes that are still structurally sound. Not an option if the pipe has collapsed.

Pipe bursting

$4,000 - $7,000

A new pipe is pulled through the old one, breaking the old pipe apart as it goes. Requires only two small access points. Works for more severely damaged pipes than lining can handle.

Traditional excavation and replacement

$3,000 - $12,000+

Digging a trench to access and replace the sewer line. The wide price range depends on length, depth, and what is above the pipe (concrete driveway versus grass). Longer runs and deeper pipes push the cost up fast.

Prices are estimates for the Santa Clarita area based on typical jobs. Your actual cost depends on the specific issue, accessibility, time of day, and materials needed. All plumbers in our network provide upfront pricing before starting work.

Permit Requirements for Sewer Line Repair & Replacement in Santa Clarita

Sewer line repair or replacement in Santa Clarita always requires a building permit. This applies to trenchless lining, pipe bursting, traditional excavation, and any work on the lateral between your house and the city main. Some Santa Clarita jurisdictions also require a right-of-way permit if the work extends under the sidewalk or street. The plumber should pull all necessary permits as part of the job. Expect the permit process to add 1 to 3 business days before work can begin.

Questions to Ask Before Sewer Line Repair & Replacement in Santa Clarita

“Trenchless or traditional dig, and which is better for my situation?”

Trenchless repair (lining or pipe bursting) costs more ($4,000 to $8,000) but preserves your landscaping and driveway. Traditional excavation ($3,000 to $6,000) is cheaper but tears up the yard. The condition of the existing pipe determines which method works.

“Is the problem on my side or the city's side?”

You are responsible for the sewer lateral from your house to the property line. The city handles the main from the property line to the street. If the blockage or break is on their side, you should not be paying for it. A camera inspection can confirm the exact location.

“Can I see the camera footage?”

The camera inspection video is your proof. It shows exactly where the break, root intrusion, or collapse is located. Keep a copy for insurance documentation.
