There are four broad ways to deal with a problem sewer lateral: keep clearing it, repair one section, line it from the inside, or replace it by trench or bursting. Each fits a different set of conditions, and the camera footage is what tells you which conditions you have.
Use this guide to narrow the options before you ask for quotes. It is not a substitute for an inspection; it helps you ask better questions about the inspection you have.
Answer in order
1. Is the pipe broken, collapsed or missing anywhere?
If yes, that section needs excavation or replacement. Lining cannot hold shape without a host pipe.
2. Is there standing water along a stretch?
If yes, a belly is likely. Re-laying that section at proper slope is the usual fix; lining keeps the dip.
3. How many defects, and how spread out?
One or two close together suggests a spot repair. Many along the run suggests lining or full replacement.
4. What material is it?
Old clay with root-filled joints often suits lining. Badly corroded cast iron may need replacement. Plastic with one bad fitting usually needs a spot repair.
5. What sits above the line?
Driveways, patios and mature trees favor trenchless methods. Open lawn makes trenching simpler.
6. Is there access at both ends?
Lining and bursting need entry points. A cleanout may need to be added first.
Methods matched to conditions
| Method | Best fit | Poor fit |
|---|---|---|
| Scheduled clearing | Light roots, sound pipe, budget timing | Broken pipe, bellies, frequent backups |
| Spot repair | One isolated defect | Defects along the whole run |
| Lining | Root-filled joints and cracks in round pipe | Collapses, bellies, severe offsets |
| Pipe bursting | Brittle pipe along a straight run under hardscape | Bellies, crowded utilities |
| Open trench | Bellies, collapses, route changes, open lawn | Line under driveways or valued trees |
Shortcuts for common results
- IfRoots at most clay joints, pipe round, no sagThenAsk about lining and compare with replacement.
- IfOne crushed section under the lawnThenAsk about a spot excavation.
- IfBelly plus roots elsewhereThenAsk about re-laying the belly and lining or replacing the rest.
- IfCorroded cast iron under the slabThenAsk about descaling and lining versus opening the floor.

Common questions
Can I decide without a camera inspection?
Not reliably. The questions in this guide depend on what the footage shows.
What if two plumbers recommend different methods?
Ask each to explain against the same footage. More than one method can be reasonable.
Is trenchless always better?
No. It avoids digging but cannot correct every problem, especially bellies.
