Sewage backing into your home is a Category 3 biohazard situation that needs to stop. But the right long-term fix โ clearing, trenchless lining, or excavation โ depends on what's causing it. Masters Plumbing Service uses CCTV cameras in Kentfield to find out exactly what you're dealing with before any repair recommendation is made.

The repair method โ clearing, lining, or digging โ should follow from specific failure documentation. We show you that footage before you sign anything.
We push a CCTV camera through your sewer line before recommending anything. The footage shows blockage type, joint conditions, pipe material, depth, and structural defects โ precisely located by distance from the cleanout. You see what we see.
Trenchless lining costs significantly less than excavation in most scenarios and preserves landscaping, driveways, and hardscape. Not every sewer failure qualifies โ we tell you honestly when it does and when it doesn't.
Fully collapsed pipe sections, severe pipe belly (negative grade), and pipe offset too severe to line require physical excavation. 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.
Sewer line repair in most CA jurisdictions requires a permit and inspection. We pull the permit, coordinate the inspection, and provide 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.
Tree roots enter sewer lines at joint gaps and grow into substantial obstructions that can completely block flow. Our electric root cutter โ a bladed head on a sectional cable machine โ cuts root masses back to the pipe wall, restoring full pipe diameter. We follow with a CCTV re-scope to confirm clearance.

CIPP lining works on pipes with cracks, root intrusion at joints, and minor deformation โ as long as the host pipe can maintain the liner during curing. We assess liner candidacy from camera footage before committing to this method.
New pipe โ typically SDR-35 PVC at code-specified depth and grade โ is installed with proper joint couplings, backfilled, and surface-restored. Post-repair camera confirms grade and joint integrity.
A standalone camera inspection โ without clearing or repair โ is useful for pre-purchase due diligence, insurance documentation, or understanding why a drain is performing poorly. We run the camera, record footage with distance markers, and provide a written scope report.

Active sewage backup into a structure is an emergency requiring immediate response. We dispatch, clear the blockage to restore drain function, document the affected area, and schedule the camera scope to assess underlying cause โ same-day or at the earliest opportunity.
Homes with known root-prone sewer lines benefit from scheduled root cutting and camera inspection on a 12โ18 month cycle. This prevents the root mass from reaching a blockage point and gives early warning of any joint deterioration progressing toward structural repair.
Here's how a Masters Plumbing Service sewer line call plays out in Kentfield, CA.
Tell our dispatcher what you're experiencing โ backed-up fixtures, gurgling drains, sewage smell โ so we arrive prepared with the right equipment.
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, CIPP 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.
Main sewer backed up on a Saturday. Masters Plumbing Service came out within 2 hours, cleared the blockage with a cable machine, then ran the camera. Found root intrusion at three clay tile joints between 22 and 46 feet from the cleanout. Presented trenchless lining vs. spot excavation with pricing for both. I chose lining โ completed Monday, camera confirmed sealed joints, permits closed the following week.
Pre-purchase scope. Tech ran the camera, gave clear narration on footage, and identified that the main cast iron line had interior corrosion narrowing the pipe to about 60% of original diameter. 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.
