Trenchless Sewer Repair
Trenchless sewer repair fixes an underground line through small access points instead of an open trench — usually by pipe bursting or cured-in-place lining. It saves landscaping, driveways, and time. But it is not right for every line: collapsed pipes and severe bellies may still need digging. FlowFast connects you with an independent local plumber who can assess your line honestly.

Sewer Line Repair & ReplacementSewer line problems? Trenchless vs. traditional replacement, warning signs, and how to get connected with an independent local plumber for sewer work.
View all Sewer Lines servicesTrenchless methods exist because digging up a yard, driveway, or patio to reach a sewer line is enormously disruptive. The two main approaches both work through small entry pits: pipe bursting pulls a new pipe through the old one, fracturing the damaged pipe outward; cured-in-place lining inserts a resin-saturated sleeve that hardens into a new pipe inside the old one. Both leave your landscaping, concrete, and hardscaping largely intact, and both typically finish faster than open-trench replacement. Permits are still usually required, and utilities must be marked before any excavation — even small pits.
The honest caveat is that trenchless is a solution for the right pipe, not every pipe. A fully collapsed line cannot be bursted or lined because there is no path for the equipment; severe bellies — sagging sections that hold water — usually need regrading by excavation. A camera inspection first is non-negotiable, because it reveals which method fits. FlowFast Plumbing is a referral service — we connect you with an independent local plumber who can camera your line and tell you straight whether trenchless will work or digging is the real answer.
Warning signs
Signs you need this service
- A camera inspection showed cracks, root intrusion, or corrosion — damage trenchless methods are designed to fix.
- Your sewer line runs under a driveway, patio, mature landscaping, or other features you do not want excavated.
- You need the line fixed with minimal disruption to daily life, since trenchless jobs typically finish faster than trenching.
- A previous quote recommended full excavation, and you want a second opinion on whether trenchless is viable.
What to expect
The process, step by step
The pro cameras the line first to confirm trenchless is viable — checking for collapses or bellies that would rule it out.
Permits are pulled and utilities marked, then small access pits are dug at the entry and exit points of the repair section.
Depending on the method, a new pipe is pulled through the old one or a resin liner is inserted and cured in place.
The line is camera-verified after the work, pits are backfilled, and you get documentation of the completed repair.
Prevention
How to avoid this problem
- After a trenchless repair, keep roots away from the line — new pipe resists roots better, but joints and connections remain vulnerable.
- Schedule periodic camera checks to confirm the repaired section and the rest of the line are holding up.
- Avoid flushing wipes, grease, and other clog-makers that stress any sewer line, repaired or original.
