For decades, fixing a damaged sewer line meant one thing: digging a trench the entire length of the pipe, tearing up your yard, driveway, or landscaping in the process. Trenchless sewer repair changed that. Today, most sewer line problems can be repaired or fully replaced through small access points, without the extensive excavation that used to be unavoidable.
If you're facing a sewer line repair, here's what trenchless methods actually involve, and how to know if your situation is a good fit.
What "Trenchless" Actually Means
Trenchless sewer repair covers two main techniques, both of which work through one or two small access points rather than a continuous trench along the entire pipe route.
Pipe Lining (CIPP)
A resin-coated liner is inserted into the existing damaged pipe and inflated, then cured in place to form a smooth, durable new pipe within the old one.
- Best for cracks, small breaks, and root intrusion
- Doesn't require removing the old pipe
- Slightly reduces the pipe's interior diameter
Pipe Bursting
A new pipe is pulled through the old one while a bursting head fractures and pushes the old pipe outward into the surrounding soil, replacing it in a single pass.
- Best for severely damaged or collapsed sections
- Fully replaces the pipe, not just lines it
- Maintains or increases the original pipe diameter
A camera inspection determines which method fits your situation — or whether a section of your line is too severely damaged for either trenchless method and needs traditional excavation instead.
Trenchless vs. Traditional Excavation
| Factor | Trenchless | Traditional Excavation |
|---|---|---|
| Typical timeline | 1 day | 2–5 days |
| Yard disruption | Minimal — small access points | Full trench along pipe route |
| Landscaping restoration | Rarely needed | Often required |
| Best for | Cracks, root intrusion, most damage | Severely collapsed sections |
| Total cost (including restoration) | Often lower overall | Repair cost plus restoration |
How the Process Works
Camera Inspection
We see the exact condition and location of the damage first.
Access Points Dug
One or two small pits are dug at each end of the affected section.
Lining or Bursting
The chosen method repairs or replaces the pipe through those access points.
Final Camera Check
We confirm the line is clear and the repair holds before backfilling.
When Trenchless Isn't the Right Fit
Trenchless methods aren't universal. A severely misaligned pipe, one with significant bellying or sagging, or a section that has fully collapsed rather than just cracked, sometimes needs traditional excavation for that specific segment to be corrected properly. Similarly, if your sewer line's exact location is unclear or access points would need to be placed somewhere impractical, traditional methods may still be the more reliable choice.
Get a camera inspection before assuming either way. Some homeowners assume trenchless repair is always possible, while others assume their older clay pipe automatically needs full excavation. A camera inspection is the only reliable way to know which approach actually fits your specific situation.

Trenchless repair's per-foot repair cost is sometimes comparable to or slightly higher than traditional excavation. But once you account for the cost of restoring landscaping, driveways, walkways, or hardscaping that a full trench would disturb, trenchless methods are frequently the more cost-effective choice overall, not just the more convenient one.
Frequently Asked Questions
How long does trenchless sewer repair take?
Most trenchless sewer repairs are completed in a single day, compared to several days for traditional excavation, since there's no need to dig a full trench or restore landscaping afterward.
Is trenchless sewer repair more expensive than traditional excavation?
The direct repair cost is often comparable or slightly higher, but trenchless methods typically save money overall once you factor in the cost of landscaping restoration, driveway or walkway repair, and the shorter labor time traditional excavation would require.
Can trenchless repair fix a completely collapsed sewer line?
It depends on the severity. Pipe bursting can often replace a collapsed line, but a severely misaligned or fully caved-in section sometimes requires traditional excavation for that specific segment, even if the rest of the project uses trenchless methods.
