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 Graton, 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.
Fully collapsed pipe sections, severe pipe belly (negative grade), and pipe offset severe enough to block flow require physical excavation to repair. We locate the defect precisely on camera, mark the dig site, call for utility locates, excavate cleanly, replace the failed section, and backfill and restore the surface.
This documentation matters for home sales, insurance claims, and warranty enforcement. We provide it as standard practice, not as an add-on.
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.
New pipe โ typically SDR-35 PVC or Schedule 40 at code-specified depth and grade โ is installed with proper joint couplings, backfilled in lifts, and surface-restored. Post-repair camera confirms grade and joint integrity.
Camera inspections are commonly requested by real estate buyers evaluating older homes in Graton 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.
If sewage is actively backing up, we dispatch immediately. If it's a recurring slow drain situation or a pre-purchase scope request, we schedule the earliest available slot. Either way, the first on-site action is accessing the cleanout.
You watch the footage with the technician. We point out each observation and explain what it means for repair options before presenting any quote.
Based on camera findings, we present the repair options appropriate for what was found โ clearing and maintenance, trenchless lining, spot excavation, or full replacement โ with flat-rate pricing for each. We explain the trade-offs between methods clearly.
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.

Our sewer technicians are familiar with the pipe ages, materials, and infrastructure conditions common in Graton neighborhoods, which speeds up diagnosis and repair planning.

Don't pay for a clearing that won't hold, or an excavation quote based on guesswork. Masters Plumbing Service scopes first in Graton, CA so you know exactly what you're repairing before you spend anything.
