How to price sewer line replacement, in short: camera the line first, pick the method the footage supports, then add crew hours at a project crew rate, machine time, pipe, permit, restoration and disposal, and divide by one minus your margin. Our worked 60-foot open-trench lateral costs $5,180.58 and sells for about $7,405 at a 30% margin, or $123 a foot.

A sewer replacement is a project, not a service call, and pricing it like one is how shops lose money on it. The crew is on one site for days, a machine is working, and the yard, driveway or street has to be put back. This guide uses the cost method from our plumbing price book guide, adjusted for multi-day work, and prices one 60-foot lateral three ways: open trench, pipe bursting and lining.

Key takeaways

Quote from the camera, not the call. The footage decides whether lining, bursting or digging will work.
Use a project crew rate for multi-day jobs: our example is $177.13 per crew hour for a plumber and a helper.
Charge every machine per use: excavator, bursting rig, fusion machine, lining kit and camera.
Call 811 a few business days before you dig. Indiana 811, for one, doesn't locate private lines.
Trenches 5 feet or deeper need a protective system under OSHA 1926.652, unless they're in stable rock.
Sanity check: This Old House (March 2026) lists $50–$200 a foot for open trench and $60–$250 for trenchless.

What rate should you use for multi-day sewer work?

Use a project crew rate built the same way as your service rate, but with a higher billable ratio. Our price book example comes to $174.20 per billable hour for a plumber on service calls, where only half of paid hours are billed because of driving and supply runs. On a two-day dig the crew arrives once and works the job, so more of each paid hour is billable. Example numbers; use your own:

Line	Calculation	Per billable hour
Plumber, $32/hr + 30% burden	$41.60 ÷ 0.80 billable ratio	$52.00
Truck share (as in the price book)	$16,000 ÷ 1,000 hours	$16.00
Overhead share (as in the price book)	$75,000 ÷ 1,000 hours	$75.00
Plumber project hour		$143.00
Helper, $21/hr + 30% burden	$27.30 ÷ 0.80	$34.13
Crew hour, plumber + helper		$177.13

We keep the full truck and overhead share on the plumber's hour, so a big job still carries its part of the office, and add the helper at wage cost only. If your overhead grows with headcount, give the helper a share too. For reference, the BLS May 2025 median wage was $30.67 an hour for plumbers, pipefitters and steamfitters and $20.36 for their helpers.

Which method should the quote use: open trench, bursting or lining?

The method should be whichever one the camera footage and the site support, and the quote should say why. Each one fails in a predictable way when it's sold for the wrong line:

Method	When it fits	When it doesn't	Main cost drivers
Open trench	Collapsed or bellied pipe, shallow line, open yard, or a grade problem to fix	Driveways, patios, mature trees or a deep line under a street	Crew days, excavator, restoration, trench protection at 5 ft+
Pipe bursting	Broken or undersized pipe on a fairly straight run, with room for two pits	Many bends, a sag you need to regrade, or utilities close to the line	Bursting rig, HDPE pipe and fusion, two pits
Lining (cured in place)	Cracks, joint leaks and roots in pipe that still holds its shape	Collapsed, bellied or badly offset pipe	Liner and resin kit, descaling, camera before and after

Offer the methods that fit as options rather than picking one for the customer. A good, better, best quote works well here: a spot repair where it's honest, a full replacement, and a full replacement with a new two-way cleanout and a longer warranty.

What should you check before you dig?

Check the locates, the permits and who owns each section of pipe before you put a date on the quote, because each one changes the price:

811 locates. The Common Ground Alliance's 811 site says anyone who plans to dig should call 811 a few business days before digging, that state laws vary, and that you must confirm every utility has responded before you start.
Private lines. 811 marks the member utilities' lines. A City of South Bend notice says Indiana 811 doesn't locate individual private lines and only locates water and sewer mains in the public right-of-way, so plan to locate private lines with your own locator or camera sonde.
Ownership. Many sewer agencies make the owner responsible for the whole lateral. Union Sanitary District in California says the owner maintains it under the sidewalk and street too, up to the public main.
Permits. The same district requires its repair permit before any work starts, and an encroachment permit from the city for digging in a street or right-of-way. Price both, plus traffic control if the street is involved.
Trench depth. OSHA 1926.652 requires a protective system such as sloping or a trench box for excavations 5 feet deep or more, and for shallower ones where a competent person sees signs of a cave-in. Deep lines add shoring, time and a wider dig.

How do you price a 60-foot sewer replacement, step by step?

Price each method line by line at the $177.13 crew hour and a 30% margin. The job: a 60-foot 4-inch lateral, about 4 feet deep, from the house cleanout to the property-line connection, across a lawn. All equipment and material figures are example numbers; replace them with your own costs and supplier quotes.

Line	Open trench	Pipe bursting	Lining
Crew hours at $177.13	16 h: $2,834.08	16 h: $2,834.08	8 h: $1,417.04
Descale or jet before lining (plumber, 2 h at $143 + $70 jetter)	−	−	$356.00
Excavator (rental or your per-use charge)	2 days: $900.00	1 day for pits: $450.00	−
Bursting rig and fusion machine, per use	−	$400.00	−
Lining equipment, per use	−	−	$250.00
Pipe, fittings, cleanout, bedding	$600.00	$700.00 (HDPE)	$1,800.00 (liner and resin)
Camera, 0.5 h at $143 + $25 per use	Final: $96.50	Final: $96.50	Before and after: $193.00
Permit (example; varies by city)	$350.00	$350.00	$350.00
Restoration: backfill, grade, seed	$250.00	$150.00	−
Spoils and old pipe disposal	$150.00	$50.00	−
Total cost	$5,180.58	$5,030.58	$4,366.04
Price at 30% margin (÷ 0.70)	$7,405	$7,190	$6,240
Per foot	$123	$120	$104

How the equipment charges work: a bursting rig and fusion machine that cost $60,000 together and do 30 jobs a year for five years come to $400 per job before repairs. Do the same sum for your excavator if you own one instead of renting. Leave the machine out and the crew pays for it out of profit, the same mistake our drain cleaning pricing guide warns about for jetters.

On an open lawn the three prices land close together. The gap opens with hardscape: if the trench crosses a driveway, add sawcut, haul-off and new concrete (example: 40 square feet at $15 a square foot of cost is $600, or $857 more in the open-trench price) while the trenchless prices don't move. That is the honest case for trenchless, and it belongs on the quote.

A sanity check against what homeowners read: This Old House, updated March 30, 2026, puts traditional replacement at $50 to $200 a foot and trenchless at $60 to $250 a foot, with camera inspections at $100 to $500 and permits at $100 to $1,000. If your per-foot price sits outside those ranges, check your hours and costs before you touch the margin.

How do you use camera footage to win and protect the job?

Use the footage as the evidence for every line on the quote. Customers get several prices for a job this size, and the shop that shows the break, the root mass or the belly on screen is easier to say yes to. Before you leave the first visit:

Record the full run and note the footage and depth of each defect from the locator.
Mark the cleanout, the defects and the property line on a site sketch or a photo of the yard.
Show the customer the screen and explain which methods the footage rules out.
Keep the video. It is your record if the customer, the city or a later plumber questions the scope.
Record the new line after the work, so the final video closes out the job and backs your warranty.

What should a sewer replacement quote say?

Method, length, pipe size and material, and where the work starts and stops (cleanout to property line, or to the main).
Camera findings in one line each, with footage and depth.
Permits, inspections and locates, who arranges them, and the lead time.
Restoration: what you put back (backfill, grade, seed) and what you don't (sod, irrigation, pavers), with unit prices for concrete.
Exclusions: rock, groundwater, a deeper main than expected, and damage to unmarked private lines, each priced before work.
Deposit, payment terms and warranty. See how much deposit to ask for on a job this size.

What mistakes make sewer jobs lose money?

Using the service-call rate on a multi-day job, or the reverse: billing a two-hour repair at the project rate.
No per-use charge for machines you own.
Selling lining for pipe the camera shows has collapsed. It fails, and you own the callback.
Leaving restoration vague. “Backfill” and “put the yard back” are different prices.
Never comparing estimated with actual hours. Log estimated and actual crew hours on the next few digs.

Where CrewRobin fits

Keep the crew hour, machine charges and restoration lines in CrewRobin's price book and send the methods that fit as good, better, best quotes the customer picks and signs online, with follow-up texts on day 2, 5 and 10. Ask for a deposit when the quote is approved, paid by card through your own Stripe account and taken off the final invoice. Technicians can attach photos of the camera screen and mark them up with arrows and circles; CrewRobin stores photos, not video, so keep the recording on the camera. CrewRobin doesn't book 811 locates or pull permits for you. See how it works for plumbers.

Frequently asked questions

How much should a plumber charge per foot for sewer line replacement?

Work it out from your own costs rather than a per-foot rule. Our worked 60-foot lateral comes to about $123 a foot open trench, $120 bursting and $104 lining at a 30% margin. This Old House (March 2026) lists $50 to $200 a foot for open trench and $60 to $250 for trenchless.

Is trenchless sewer replacement more profitable than open trench?

Not by itself. On an open lawn the prices land close together. Trenchless pays off when it avoids expensive restoration such as driveways, patios or a street cut, and when your equipment is busy enough to keep its per-use charge low.

Do I need to call 811 for a sewer lateral replacement?

Yes. The 811 site says anyone who plans to dig should call a few business days ahead and wait for every utility to respond. 811 may not locate private lines; Indiana 811, for example, only locates water and sewer mains in the public right-of-way.

When does a sewer trench need shoring?

OSHA 1926.652 requires a protective system for excavations 5 feet deep or more unless they're entirely in stable rock, and for shallower ones where a competent person sees signs of a possible cave-in. Price the trench box or sloping into deep jobs.

Should a sewer replacement quote include a camera inspection?

Yes. Camera the line before you quote and after the work. The first video decides which methods can work; the final video closes the job and backs your warranty.
