What Is Trenchless Sewer Repair?
Fix your sewer line without tearing up your yard — here’s how it works
Quick Answer
Trenchless sewer repair fixes a damaged sewer line without digging a long trench through your yard or driveway. Instead, we work from just one or two small access points. The two main methods are pipe lining (inserting a new liner inside the old pipe) and pipe bursting (breaking the old pipe while pulling a new one through). It’s faster, less invasive, and often costs less than traditional excavation once restoration is factored in.
Why Traditional Sewer Repair Is So Disruptive
Before trenchless methods existed, repairing a sewer line meant digging a long trench — sometimes 50 to 100+ feet — through your yard, garden, or driveway. Trees got removed. Landscaping got destroyed. Concrete got broken up. And the restoration work after the repair could add thousands to the total cost.
At Top Shelf Plumbing Pros, most of our customers are genuinely relieved when we tell them a trenchless option is available. In our opinion, it’s one of the biggest advances in plumbing in the last few decades.
The Two Main Trenchless Methods
Pipe Lining (CIPP)
We insert a resin-soaked liner into the damaged pipe, inflate it, and let it cure into a smooth new pipe inside the old one. Seals cracks and resists future root entry. Best for pipes that are cracked but still structurally intact.
Pipe Bursting
We pull a bursting head through the old pipe, fracturing it outward while simultaneously pulling a new HDPE pipe into place. A full replacement — from just two access points. Best for severely damaged or collapsed pipe.
Trenchless vs. Traditional Excavation
| Factor | Trenchless Repair | Traditional Excavation |
|---|---|---|
| Yard disruption | Minimal — 1–2 small access points | High — full trench required |
| Driveway/concrete damage | Usually none | Often significant |
| Time to complete | 1–2 days typically | Several days to a week+ |
| Landscaping impact | Very low | High — trees/plants may be removed |
| Total cost (incl. restoration) | Often comparable or lower | Higher when restoration included |
| New pipe lifespan | 50+ years | 50+ years |
When Is Trenchless the Right Choice?
| Situation | Best Option |
|---|---|
| Cracked pipe, structurally intact | Pipe lining (CIPP) |
| Root intrusion with pipe damage | Pipe lining or pipe bursting depending on severity |
| Collapsed or severely damaged pipe | Pipe bursting or excavation |
| Severely misaligned pipe sections | Excavation may be required |
| Pipe under driveway or landscaping | Trenchless strongly preferred |
📷 Why a Camera Inspection Comes First
The only way to know which method applies to your situation is a camera inspection. Before we recommend any repair approach, we need to see exactly what’s inside the pipe. That inspection drives the recommendation — not a default preference for one method.
What to Expect During a Trenchless Repair
- Camera inspection — we inspect the full length of the line to confirm damage location and pipe condition.
- Cleaning — we hydro jet the line to remove all debris, roots, and buildup before any repair begins.
- Access point preparation — we excavate 1–2 small pits at the entry and exit points of the repair area.
- Repair — we insert and cure the liner (CIPP) or pull the new pipe through (pipe bursting).
- Final inspection — we run the camera through the repaired line to verify the job is complete.
- Cleanup — we backfill the small access pits and leave your property clean.

Frequently Asked Questions
Is trenchless sewer repair as good as traditional replacement?
Yes — when the right method is applied to the right situation. Both CIPP lining and HDPE pipe used in pipe bursting are rated for 50+ years.
How much does trenchless sewer repair cost?
Trenchless repair typically runs $3,000 to $8,000 depending on method, pipe length, and access conditions. When yard and driveway restoration costs are factored in, it’s often comparable to or less than traditional excavation.
Can all sewer pipes be repaired with trenchless methods?
Most can, but not all. Severely misaligned sections or pipes that have fully collapsed in multiple locations may still require traditional excavation. A licensed plumber with camera inspection equipment can determine which approach is feasible.
How do I know if I need trenchless repair or just cleaning?
A camera inspection tells you. If the pipe is structurally intact and the problem is just buildup or roots, cleaning may be all that’s needed. If there’s cracking or corrosion, repair is necessary.
