A failing sewer line forces one big decision: rebuild the pipe from inside (trenchless lining) or dig it out and replace it (open trench). Both end with a working sewer. Everything else, cost, timeline, landscaping, and what your property looks like in two weeks, depends on choosing the method your pipe and your yard actually suit.
The Two Methods, Briefly
Cured-in-place lining (CIPP) threads an epoxy-saturated felt tube through the failing section, presses it against the old walls, and cures it into a seamless new pipe inside the old one. Two small access points, no trench. Open-trench replacement excavates the failing run, removes the old pipe, and installs new PVC on proper bedding, which is the only option when the pipe is gone rather than merely damaged.
Side by Side
| Factor | Trenchless lining | Open-trench replacement |
|---|---|---|
| Typical Linden range | $3,000 - $7,000 | $3,500 - $10,000+ |
| Timeline | 1-2 days typical | 2-3+ working days plus restoration |
| Yard damage | Two access points | Full trench along the run |
| Hardscape impact | None if access avoids concrete | Cutting and re-pouring crossings |
| Root re-entry | Eliminated (seamless barrel) | Eliminated (new pipe, new joints) |
| Works on collapsed pipe | No | Yes, the only option |
| Permits and inspection | Yes, same as digging | Yes, with open-trench inspection |
How the Decision Actually Gets Made
The camera decides before the brochure does. Lining needs a host pipe: a barrel that has cracked, scaled or grown roots can be rebuilt, but a run that has collapsed, deformed past shape or bellied severely cannot. That is why every honest trenchless quote starts with a scope, and why a contractor who quotes lining without one is selling a product, not a repair.
Where both methods work, the property tips the scale. A lateral under a driveway, mature landscaping or a patio is lining's home turf, because the dig's restoration costs are what blow up replacement budgets. A shallow run under open grass with room for equipment often prices out close enough that either answer serves, and the tiebreaker becomes timeline.
The Costs People Forget to Compare
- Restoration: seed and soil versus concrete, sprinklers and fence lines; restoration is where open-cut invoices hide their real size.
- Days offline: a lined run returns to service in a day or two; a dug run plus re-poured driveway can stretch a week.
- Future root access: both methods stop roots, but the liner does it by deleting the joints, not by installing new ones.
- Documentation: whichever method you choose, keep the final camera footage; it is the record of what is under your yard for decades.
What We Recommend in Linden
For the town's mid-century clay laterals with root-worn joints and intact barrels, lining usually wins on every axis that matters to a homeowner. For collapsed runs, severe bellies and pipes crushed under old driveways, replacement is the only honest option, and quoting a dig that includes the city inspection is part of the job. The 2026 cost breakdown for both paths lives in our price guide, and the service pages walk each process in full: trenchless repair and replacement.
