A sewer line failure ranges from a root intrusion that responds to clearing, to a collapsed pipe section that requires physical repair. The difference between those scenarios โ and their costs โ is determined by a CCTV camera scope, not a guess. Masters Plumbing Service's sewer techs in Princeton, MN 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 certainty about what you're repairing and why before any ground is disturbed. Our CCTV-first approach protects you from misdiagnosis and unnecessary excavation costs.
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.
For sewer lines with root intrusion, cracked joints, or minor pipe deformation that haven't fully collapsed, CIPP lining installs a structural epoxy sleeve inside the existing pipe without excavation. The liner seals every joint and resists future root infiltration.
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 MN 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.
From a simple root clearing to full trenchless lining or spot excavation, our sewer crew in Princeton, MN has the equipment and certification to execute.
Root cutting is a temporary measure if joints remain open. After cutting, we assess whether CIPP lining to seal the entry points is warranted, or whether regular maintenance clearing is the right long-term plan.

CIPP lining installs a flexible epoxy-saturated felt liner inside the existing pipe. 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 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.

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 next steps.
A 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 excavation. Every sewer repair we do in Princeton, MN 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.
You watch the footage with the technician. We point out each observation and explain what it means for repair options before presenting any quote.
For trenchless vs. excavation decisions, we lay out cost difference, disruption difference, and long-term outcome expectation for each option so you can make an informed choice.
Required permits are closed out with the local inspection. You receive camera footage, written scope report, permit inspection sign-off, and warranty documentation.
Had a sewer problem that two other companies cleared without scoping. It backed up again within 8 weeks both times. Masters Plumbing Service scoped before doing anything and found a significant pipe belly at 34 feet holding standing water โ that's why clearing kept failing. They excavated precisely, replaced a 4-foot section, confirmed grade on camera after backfill. No recurrence.
We bought an older home in Princeton and wanted the sewer scoped before closing. Masters Plumbing Service ran the full line, found an offset joint at 58 feet creating a partial obstruction and some root infiltration at three additional joints. Written report in hand, we negotiated a $4,200 repair credit from the sellers before closing. The scope paid for itself many times over.
Commercial building where two prior companies told us we needed full excavation at $28,000. Masters Plumbing Service scoped it, found root intrusion and joint cracking but no pipe collapse, and quoted trenchless lining at roughly a third of that cost. Lining completed in two days. Post-cure scope confirmed excellent adhesion. The camera diagnosis saved us a significant amount of money.
