Backed-Up or Collapsed Sewer Line in Cotati, CA? We Fix It Right
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 β and their costs β is determined by a CCTV camera scope, not a guess. Masters Plumbing Service's sewer techs in Cotati, CA run the camera first, show you exactly what's there, and recommend the repair method that actually resolves the specific failure.

Our Approach
4 Principles Behind Every Sewer Job We Run
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.
π·
Camera Diagnosis Before Any Quote
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.
π
Trenchless Pipe Lining β No-Dig Option
Trenchless lining costs significantly less than excavation in most scenarios and preserves landscaping, driveways, and hardscape. Not every sewer failure qualifies for lining β we tell you honestly when it does and when it doesn't.
βοΈ
Excavation When Required β Done Properly
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.
π
Permitted Work & Written Documentation
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.

What We Diagnose and Repair on Sewer Lines
Sewer line problems fall into distinct categories β each with its own repair approach. Here's how we handle each one.
Root Intrusion
Root Cutting & Mechanical Clearing
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.
Structural Repair
Trenchless CIPP Pipe Lining
CIPP lining works on pipes with cracks, root intrusion at joints, minor deformation, and localized damage β as long as the host pipe can maintain the liner in position during curing. We assess liner candidacy from camera footage before committing to this method.
Excavation
Open-Cut Sewer Line Replacement
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.
Diagnosis
CCTV Sewer Line Camera Inspection
A standalone camera inspection β without any clearing or repair β is useful for pre-purchase due diligence, insurance documentation, or understanding why a drain is performing poorly before committing to a repair approach. We run the camera, record footage with distance markers, and provide a written scope report.
Emergency
Active Sewer Backup Response
The immediate goal of an emergency sewer call is stopping the backup. The camera and permanent repair follow once the situation is contained. We don't leave you with just a cleared drain and no plan for what to do next.
Preventive
Sewer Line Maintenance Program
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.

What Cotati, CA Homeowners Say About Our Sewer Work
β β β β β
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 β 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 β and they did.
β L. & P. Brennan, Cotati, CA
β β β β β
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.

Common Questions
Common Questions About Sewer Line Repair in Cotati, CA
The only reliable answer comes from a CCTV camera scope. A sewer line that clears fully and shows no structural defects on camera needs maintenance, not repair. A line that shows joint offsets, collapsed sections, a belly (reverse grade), or severe pipe deterioration needs repair β because clearing will keep failing until the structural issue is addressed.
CIPP liners installed correctly are rated for 50+ years of service life. The epoxy composite material resists root intrusion and corrosion, and the seamless interior surface actually flows better than the original pipe it's installed inside. Long-term performance is well-documented in municipal infrastructure projects where lining has been the standard rehabilitation method for decades.
Cost varies significantly based on repair method, pipe length, depth, and access conditions. A camera scope runs $150β$350 as a standalone service. Root cutting and clearing runs $200β$600 depending on line length. Trenchless lining for a residential main sewer run typically ranges from $3,500 to $10,000+ depending on footage and pipe diameter. Spot excavation for a localized failure is typically $2,500β$6,000 depending on depth and surface restoration needed.
A wet, soft, or sunken area over the path of the sewer line often indicates an exfiltration leak β sewage escaping the line into the surrounding soil. This can happen from a cracked pipe, a failed joint, or a collapsed section. Soil saturation from a leaking sewer line eventually causes the ground above it to sink as the saturated soil shifts.
Yes, in most jurisdictions in CA, sewer line repair β particularly any work involving excavation, pipe replacement, or trenchless lining β requires a permit and inspection. Clearing and camera scoping generally do not. We pull required permits as part of the job and coordinate the inspection. Permit costs are disclosed in your flat-rate quote.
Often, yes β if the camera footage confirms the pipe is a candidate for trenchless lining. CIPP lining accesses the pipe through the existing cleanout or a small access point and installs the liner from inside the pipe β no trenching over the pipe run.
