Most residential sewer line replacements take 1 to 3 days of actual work. Trenchless replacement is often done in a single day, while a traditional dig-and-replace job can take 2 to 3 days, or longer for deep lines, long runs, lines under a slab or when an inspection has to be scheduled before backfill.
The work itself is only part of the timeline. Locating utilities, pulling a permit and waiting for an inspector can add days before or during the job. Here is what a typical project looks like from start to finish.
What Does a Typical Timeline Look Like?
| Step | Typical time |
|---|---|
| Camera inspection and locating | 1 to 2 hours |
| Quote and approval | Same day to a few days, your pace |
| 811 utility marking | At least 2 full working days before digging |
| Permit | Varies with the city |
| Excavation or pit digging | Half a day to a full day |
| Pipe removal and installation | Half a day to a full day |
| Inspection | Depends on the inspector’s schedule |
| Backfill and cleanup | A few hours to half a day |
Once you approve the estimate, we schedule the repair based on how urgent it is, crew availability, permit requirements and whether 811 locating is needed. An active sewer emergency gets stabilized first. For planned digging, we line up the permit and utility marks before the crew breaks ground.
Trenchless vs. Dig and Replace
Pipe bursting and pipe lining only need one or two small access pits, so there is far less digging and backfilling. Many trenchless jobs finish in one day. A full trench takes longer because the whole line is opened, laid with new pipe on proper bedding and then filled and compacted. Read trenchless vs. dig-up sewer repair for the full comparison.
What Can Make It Take Longer?
- Depth. Deep lines need shoring and more careful digging. See how deep sewer lines are buried.
- Under the slab. Tunneling or cutting through a floor adds time.
- Driveways and patios. Concrete has to be cut and later replaced.
- Weather. Heavy rain floods trenches and softens clay soil.
- Other utilities. Gas, water or cable lines close to the sewer mean slower hand digging.
- Surprises. A second break or a failing connection at the main.
How Long Will You Be Without Plumbing?
You cannot send water down the drains while the old line is out. For a trenchless job, that is often part of one day. For a trench job, it is usually the working hours of each day, and many crews reconnect a temporary line or leave the new pipe usable overnight. Plan on limiting showers, laundry and dishwashing during the work.
A Typical Pine Bluff Example
Take a 1960s ranch house with about 60 feet of clay line to the street. Day one: the camera finds several cracked, root-filled joints, the line is located and marked, and the quote is approved. After the utility marks come back and the permit is in, the crew digs, lays new PVC on proper bedding and connects it at both ends in one working day. The inspector checks the open trench, and the backfill and cleanup follow. The house is without drains only during working hours. Heavy clay soil after a rainy week is the most common thing that pushes a job like this back a day.
How to Prepare Your Home
- Move cars, planters and outdoor furniture from the work path.
- Know where your cleanout is. See how to find your sewer cleanout.
- Keep pets inside while the trench is open.
- Plan laundry and showers before the crew arrives.
What About After the Job?
Backfilled soil settles over the following weeks, especially after rain, so the trench line may sink slightly and need topping off. Grass usually takes a season to fill back in. A final camera run should confirm the new line is clean and properly sloped before the crew leaves.

FAQ
Can I stay home during sewer replacement?
Yes, most people do. You just limit water use while the line is disconnected.
Is trenchless always faster?
Usually, but not every line qualifies. Collapsed or badly sagging lines may still need digging.
Does the inspection delay the job?
It can. The trench usually stays open until the inspector approves the new pipe.
