A sewer line failure ranges from a root intrusion that responds to clearing, to a collapsed pipe section that requires physical repair or lining. The difference between those two scenarios โ and their costs โ is determined by a CCTV camera scope, not a guess. Masters Plumbing Service's sewer techs in Clearlake, CA run the camera first, show you exactly what's there, and recommend the repair method that actually resolves the specific failure.

Sewer line repair is expensive enough that you need to be absolutely certain what you're repairing and why before any ground is disturbed. Our CCTV-first approach protects you from misdiagnosis and unnecessary excavation costs.
No legitimate contractor recommends trenchless lining or excavation without camera footage confirming the failure type and location. If someone quotes a sewer repair without a scope, that's a red flag.
For sewer lines with root intrusion, cracked joints, or minor pipe deformation that haven't fully collapsed, CIPP (cured-in-place pipe) lining installs a structural epoxy sleeve inside the existing pipe without excavation. The liner bonds to the host pipe, seals every joint, and produces a smooth interior surface that resists future root infiltration.
Precise camera locating means we dig where the problem is, not speculatively. We document the repair with post-repair camera footage and restore the excavation site to grade.
Sewer line repair in most CA jurisdictions requires a permit and inspection. We pull the permit, coordinate the inspection, and provide you with camera footage, repair documentation, and inspection sign-off as a complete job record.
Sewer line problems fall into distinct categories โ each with its own repair approach. Here's how we handle each one.
Root cutting is a temporary measure if the joints remain open. After cutting, we assess whether pipe lining to seal the entry points is warranted, or whether the joints are tight enough that regular maintenance clearing is the right long-term plan.
Cured-in-place pipe lining installs a flexible epoxy-saturated felt liner inside the existing pipe. The liner is inverted or pulled into position, inflated against the host pipe, and cured with hot water or steam. The result is a new, jointless pipe inside the old one โ rated for 50+ years of service life.
When pipe sections have fully collapsed, when the pipe grade has reversed (creating a belly that holds standing sewage), or when root intrusion is too severe for lining to hold, traditional excavation is the correct repair. We locate the defect precisely on camera, mark the excavation footprint, call for utility locates, and dig to the pipe depth.
Camera inspections are commonly requested by real estate buyers evaluating older homes in Clearlake where sewer line condition is a known concern. Our written scope report is accepted by attorneys, insurers, and buyers' agents.
Active sewage backup into a structure is an emergency requiring immediate response. We dispatch on an emergency basis, clear the blockage to restore drain function, contain and document the affected area, and schedule the camera scope to assess underlying cause โ either same-day or at the earliest opportunity.
A written maintenance record documenting each cleaning and camera finding is useful evidence for insurance claims and demonstrates proactive maintenance if a catastrophic failure occurs.
Here's how a Masters Plumbing Service sewer line call plays out โ from your first call to a repaired, flowing sewer.
Tell our dispatcher what you're experiencing โ backed up fixtures, gurgling drains, sewage smell in the yard, slow drainage across multiple fixtures โ so we arrive prepared.
We push the camera from the cleanout and run the full line to the municipal connection or septic tank, recording footage with footage distance markers. Blockage location, pipe material, joint condition, pipe deformation, and grade issues are all documented on the recording.
For trenchless vs. excavation decisions, we lay out the cost difference, the disruption difference, and the long-term outcome expectation for each option so you can make an informed choice.
Approved repairs proceed. After completion, we run the camera again to document the repaired state. For lining jobs, the post-cure scope confirms liner adhesion and full internal diameter. For excavation repairs, the scope confirms grade and joint quality.

My main sewer line backed up on a Saturday. Masters Plumbing Service came out within 2 hours, cleared the blockage with a cable machine to restore drain function, then ran the camera. The footage showed root intrusion at three clay tile joints between 22 and 46 feet from the cleanout. They presented a trenchless lining option vs. spot excavation at each joint with pricing for both. I went with lining โ completed on Monday, camera confirmed clean and sealed joints, permits closed the following week.
Pre-purchase scope done through Masters Plumbing Service. Tech ran the camera, gave clear narration on the footage, and identified that the main cast iron line had interior corrosion narrowing the pipe to about 60% of its original diameter. We used that report to request the sellers replace the line โ and they did.
Tree roots had invaded our sewer line every year for six years. Annual clearing costs were adding up. Masters Plumbing Service scoped, confirmed the root entry points, and lined the 70-foot residential run. No roots at the 18-month re-scope. The liner sealed every joint the roots had been using.
