Replacing a sewer line is priced mostly by the foot, and the biggest swing in an Elizabeth quote is usually not the pipe. It is what sits on top of the pipe: lawn, a driveway, a sidewalk, or the street. This guide puts real 2026 price ranges next to the parts of the job that drive them, so you can read a quote and see where the money goes.
How MainStreet fits in: MainStreet Service Pros does not dig or replace sewer lines. We route your request to an independent sewer and excavation contractor that works in your town and follow up until the estimate arrives. The prices below come from published cost surveys, not from MainStreet quotes.
The short answer
- National typical range: professional sewer line replacement runs about $1,388 to $5,323, and Angi puts the average at $3,319, with jobs ranging from $225 to $10,000 (Angi, updated August 3, 2026).
- Nearby New Jersey: HomeYou lists a typical range of $994 to $7,461 for sewer line replacement in Bayonne, based on a small number of local quotes this year (HomeYou, updated October 9, 2026).
- By the foot: running new sewer pipe costs $50 to $250 per linear foot, about $150 on average, materials and labor included (Angi).
Those ranges are wide because the job changes with depth, length, and what has to be opened and put back. The rest of this guide breaks that down.
Dig-and-replace vs. trenchless: per-foot prices
| Method | Price per linear foot | When it fits |
|---|---|---|
| Full replacement (whole line, any method) | $60 to $250 | Angi's range for replacing the entire line; it does not split out digging |
| Pipe bursting | $60 to $200 | Cracked or broken pipe along a clear path, with a pit dug at each end |
| Cured-in-place lining (CIPP) | $90 to $250 | Cracks and root entry in a pipe that is still round |
Prices in every row: Angi, updated August 3, 2026. Angi also lists trenchless replacement in general at $60 to $250 per foot.
Digging is where the price climbs. Angi puts excavation alone at $50 to $200 per linear foot, depending on soil, depth, and access, and says trenching adds $4 to $12 per linear foot on top of the replacement. A Cincinnati sewer contractor's own guide puts dig-and-replace at $150 to $250 per foot and says trenchless repairs cost 25 to 30 percent less on average (CME Sewer Repair). Treat a contractor's own figures as one data point, not a market average.
Trenchless is cheaper only when the pipe qualifies. A collapsed or sagging line usually has to be dug up, which is covered on our sewer excavation page.
Example: what 50 feet could cost
"Cost to replace 50 feet of sewer line" is one of the most searched versions of this question. Using the per-foot ranges above, the pipe work alone works out to:
- Full replacement, any method (Angi): 50 feet × $60 to $250 = $3,000 to $12,500.
- Dig-and-replace (CME, one contractor): 50 feet × $150 to $250 = $7,500 to $12,500.
- Pipe bursting: 50 feet × $60 to $200 = $3,000 to $10,000.
- Lining (CIPP): 50 feet × $90 to $250 = $4,500 to $12,500.
This is simple arithmetic on published ranges, not a quote. It leaves out the camera inspection, permits, and surface restoration below, and a real Elizabeth job can land above or below it.
The costs on top of the pipe
- Camera inspection: most sewer projects need one, at $100 to $500 (Angi). Ask for the footage and the marked location of the failure.
- Excavation itself: $50 to $200 per linear foot depending on soil, depth, and access (Angi).
- Concrete over the pipe: breaking and restoring a concrete slab can push that section to $300 to $350 per linear foot (Angi).
- Driveway and yard: concrete driveway repair runs $1 to $25 per square foot, asphalt $1 to $15, and landscape or hardscape repair $1 to $25 (Angi).
- Labor: $45 to $200 per hour depending on location, experience, and complexity (Angi).
- Permits and the street: in Elizabeth the run to the city main can cross a sidewalk or street, which adds a street-opening permit and pavement or sidewalk restoration. Fees depend on who owns the road (the city, Union County, or the state), so ask the contractor to list them rather than guess.
- The 811 call: New Jersey requires at least three business days' notice through 811 before digging (NJ Board of Public Utilities). That notice sets the earliest start date.
What pushes an Elizabeth job toward the high end
- A deep pipe, which needs a wider trench or a trench box. Trenches 5 feet deep or more need a protective system such as sloping, shoring, or a trench box (OSHA).
- A failure under a driveway, porch, or slab instead of under lawn.
- A failed connection at the city main, which can mean opening the street.
- Old cast iron, clay, or fiber (Orangeburg) pipe that crumbles once it is exposed.
- Groundwater or loose fill that slows the dig.
- Findings the camera could not show, which become change orders once the trench is open.
Repair instead of replace?
Not every problem needs a full replacement. Angi lists these typical repair prices (Angi):
- Cracked pipe spot repair: $600 to $1,050.
- Root removal: $100 to $600.
- Cured-in-place lining: $80 to $250 per linear foot.
For a fuller breakdown of repair methods and prices, see our sewer line repair cost guide. If the camera shows a collapse, a long sag, or a broken connection at the main, a spot repair usually will not hold, and the job moves to sewer excavation and replacement.
How to compare two quotes
- Check that both quotes are for the same length of pipe and the same method.
- Look for the camera footage and the marked failure location behind each price.
- Find the line items for excavation, pipe, permits, and restoration. A single lump sum hides where the money goes.
- Confirm who calls 811 and who pulls the street-opening and plumbing permits.
- Read what restoration includes: topsoil and seed, concrete, sidewalk, curb, or asphalt.
- Ask what changes the price once the trench is open, and at what rate.
- Ask for the contractor's New Jersey license number and check it on the state's license lookup.
Frequently Asked Questions
How much does it cost to replace a sewer line in NJ?
Published ranges put a typical professional replacement at about $1,388 to $5,323 nationally (Angi, 2026), and HomeYou lists $994 to $7,461 for nearby Bayonne. Long runs, deep pipe, and work under a street or driveway can go well above those ranges.
How much does it cost to replace 50 feet of sewer line?
Angi's full-replacement range of $60 to $250 per foot puts the pipe work alone at $3,000 to $12,500 for 50 feet. If the line has to be dug up, one sewer contractor's own figure of $150 to $250 per foot (CME Sewer Repair) gives $7,500 to $12,500. Inspection, permits, and restoration are extra.
Is trenchless sewer replacement cheaper than digging?
Often, when the pipe qualifies. Angi puts trenchless replacement at $60 to $250 per foot and says trenching adds $4 to $12 per foot on top; one sewer contractor (CME Sewer Repair) says trenchless averages 25 to 30 percent less than digging. Trenchless work also avoids most of the yard, driveway, and sidewalk restoration. A collapsed or sagging pipe usually cannot be done trenchless.
Who pays for the part of the sewer line under the street?
In most New Jersey towns the homeowner is responsible for the lateral up to the city main, but the rules differ. Ask the City of Elizabeth where your responsibility ends before you approve a quote.
Does MainStreet replace sewer lines?
No. MainStreet Service Pros routes your request to an independent sewer and excavation contractor that works in your town and follows up on the estimate. The contractor scopes, prices, permits, and performs the work.
