CIPP cost per foot typically runs $80-$250, with many residential projects averaging $120-$180 per foot. Pipe diameter, access, cleaning, location, and whether the work requires a new access point can move a quote substantially; short repairs may also carry a minimum charge.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Residential CIPP lining | $80/ft | $150/ft | $250/ft | Common 4-6-inch sewer laterals |
| Commercial or larger pipe | $120/ft | $250/ft | $500+/ft | Usually larger diameter or more complex setup |
| Minimum project charge | $2,000 | $3,500 | $6,000 | Can apply even to short lining runs |
| Inspection and cleaning | $300 | $800 | $1,800 | May be quoted separately or included |
Typical CIPP prices for 4- to 6-inch sewer lines
For a straightforward residential sewer lateral, expect roughly $80-$250 per linear foot, or about $4,000-$12,500 for 50 feet. A common midrange quote is $6,000-$9,000 for that length when the pipe is accessible, the line can be cleaned normally, and there are no major bends or collapsed sections. For budgeting, $150 per foot is a reasonable midpoint for a standard residential run, not a guaranteed local rate.
Small-diameter pipe can cost less per foot than larger pipe, but mobilization, inspection, setup, and minimum job charges make short runs expensive on a per-foot basis. Commercial lines, storm drains, and pipes larger than 8 inches often cost $150-$500 or more per foot depending on diameter and access. Assumptions: U.S. contractor pricing, cured-in-place liner installation, ordinary access, and no major excavation or structural rebuild.
What pipe cleaning, liner, and labor add to the quote
A CIPP estimate may combine several tasks into one total. Ask whether cleaning, video inspection, reinstating branch connections, and post-installation testing are included. The cost breakdown below gives broad planning ranges; line condition and contractor pricing affect each share.
| Quote component | Typical price | Pricing basis | What changes it |
|---|---|---|---|
| Cleaning and preparation | $300-$1,800 | Per project | Roots, scale, grease, and access |
| Liner and resin | $35-$120 | Per foot | Diameter, liner thickness, and resin type |
| Installation labor | $40-$130 | Per foot | Crew, setup, length, and complexity |
| Equipment and mobilization | $500-$2,500 | Per project | Equipment needs and travel distance |
| Cutting and testing | $250-$1,500 | Per project | Branch connections and documentation |
Line items do not always add directly to the quoted per-foot rate because contractors may bundle materials, labor, equipment, and overhead. Compare the final scope and included services, not just the liner rate.
How diameter, length, and pipe damage change CIPP pricing
Diameter is a major price driver because a 10-inch liner uses more material and may require different equipment than a 4-inch residential liner. Moving from a 4-inch to an 8-inch pipe can push per-foot costs into roughly the $150-$350 range; pipes 12 inches and larger may exceed $300 per foot, especially in commercial or municipal settings.
Length affects total price, but not always the unit rate. A 20-foot repair may still incur a $2,000-$6,000 minimum, while a 100-foot run may benefit from lower mobilization cost per foot. Severe offsets, standing water, collapsed sections, or bends that prevent liner installation can require excavation or a different repair method. Get a camera inspection before accepting a full-length lining quote.
How many hours a CIPP crew needs on site
A prepared residential lateral may take a crew about 4-8 hours on site for cleaning, liner installation, curing, and verification. A complicated 50- to 100-foot run can take one or two days, while larger commercial lines may require multiple work shifts. These are site durations, not necessarily continuous labor hours; curing and setup affect the schedule.
Labor pricing varies by region and crew complexity, but a planning range of $75-$150 per worker-hour is common for specialized plumbing or rehabilitation work. A two- or three-person crew working 8 hours represents $1,200-$3,600 in labor at those rates, before equipment, materials, and overhead. Confirm whether the quote charges by footage, crew time, or a bundled project rate.
When cleanouts, roots, or disposal raise the project total
Existing cleanouts can reduce access work. If a new cleanout or excavation is needed, budget approximately $500-$2,500 for a straightforward addition, with more for concrete, landscaping, or difficult digging. Root removal and heavy descaling may add $300-$1,500, depending on severity and equipment.
Some jobs also require bypass pumping, traffic control, or restoration after access work. Those items can add hundreds to several thousand dollars on commercial or hard-to-reach sites. Ask whether debris disposal, water use, branch reconnections, and a final video recording are included. Unexpected access work is often a bigger budget risk than a small change in liner price per foot.
CIPP lining versus excavation for a 50-foot sewer repair
For a 50-foot residential line, CIPP might total $4,000-$12,500 when the pipe is suitable and access is available. Traditional excavation and replacement may run about $8,000-$25,000 or more, especially when the pipe lies under a driveway, finished yard, or foundation-adjacent area. Prices depend on local labor and restoration needs.
Excavation may be more practical when the pipe is fully collapsed, badly misaligned, or needs a change in slope. CIPP can limit surface disruption, but it does not correct every structural or drainage problem. Compare the repair method against the inspection findings and the cost to restore the surface.
Regional labor rates can shift a CIPP estimate
Urban markets and high-cost coastal areas may price CIPP work 15%-35% above a national midpoint because of labor, travel, parking, and permitting costs. Lower-cost rural areas can come in 10%-20% below that midpoint, although long contractor travel distances or limited provider availability can erase the difference.
Dense cities may also need traffic control or work-hour coordination. Rural quotes may include higher mobilization fees when the crew travels far. Request local quotes using the same pipe footage, diameter, cleaning scope, and included testing so regional comparisons are meaningful.
Ways to lower a CIPP bill without cutting necessary work
Combining nearby repairs or lining a longer confirmed section may spread setup and mobilization charges across more footage. Clear access to cleanouts, remove stored items around work areas, and provide accurate site details when requesting estimates. Avoid paying to line sound pipe unless inspection evidence supports that scope.
Request at least three written bids that state footage, diameter, preparation, liner method, curing process, branch reconnections, warranty, and exclusions. A lower quote can reflect omitted cleaning or testing rather than a cheaper equivalent service. Keep the scope consistent across bids, and weigh the total price against documented pipe condition and restoration costs.
