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 push-rod CCTV cameras in Bath 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 the specific failure documented on camera. 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 any structural defects โ precisely located by distance from the cleanout. You see what we see.
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.
Sewer line repair in most ME 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.
A standalone camera inspection โ without any clearing or repair โ 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.
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.
No guessing, no speculative digging. Every sewer repair we do in Bath, ME starts with camera footage and ends with a documented, inspected result.
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.
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.
Commercial building with a 6-inch main sewer line that had two prior clearing companies tell us we needed full excavation โ a $28,000 estimate. Masters Plumbing Service scoped it, found root intrusion and some joint cracking but no pipe collapse or belly, and quoted trenchless lining as an option at roughly a third of that cost. Lining completed in two days. Post-cure scope confirmed excellent adhesion. That camera diagnosis saved us a lot of money.

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