Once a camera inspection shows damage in your sewer line, the next question is whether to repair the damaged section or replace the whole line. There is no universal answer, but four questions get most homeowners to the right one.
1. Is the damage in one place or many?
This is the biggest factor. A single crushed section, one root-infested joint or one short sag in otherwise sound pipe is a strong case for a section repair. Defects at joint after joint along the line mean that fixing one spot leaves the next failure waiting.
2. What is the pipe made of, and how is it aging?
Pipe material sets expectations. Plastic pipe in good condition can last a very long time, so repairing one damaged spot makes sense. Cast iron that is corroded and scaled along its length, clay with roots at many joints, or bituminous fiber pipe that is starting to deform are all materials where problems tend to spread. The camera shows both the material and its condition.
3. What is above the line?
Surfaces change the math. A repair under open lawn is relatively inexpensive. The same repair under a paver driveway or a pool deck carries restoration costs that can approach the cost of a trenchless replacement of the full line. Price both.
4. What is your plan for the house?
If you are selling soon, a documented repair with camera footage may be all you need. If you plan to stay for a long time, or you are remodeling and adding fixtures, replacing a marginal line now can avoid tearing up new landscaping or hardscape later.
A quick comparison
Lean toward repair
- One or two defects in sound pipe
- Plastic pipe, or older pipe in good shape
- Damage under open lawn
- Short ownership horizon
Lean toward replacement
- Defects along much of the line
- Material deteriorating along its length
- Several past repairs or frequent cleanings
- Remodel, addition or slope problems
Don't forget the middle option
Lining can renew a full line from the inside when the pipe still holds its shape, and a point liner can fix one section without digging. Neither corrects slope, so a line with sags still needs excavation at those spots.
Get both prices. A good estimate lets you compare repair and replacement on the same footage. If a contractor only offers one, ask why the other is not appropriate for your line.
