As a 2026 planning estimate, lining a full 15–25 m residential sewer lateral with a cured-in-place pipe (CIPP) liner typically quotes about $9,000 to $28,000 CAD in Canada, or roughly $500 to $1,200 per metre after setup. A single sectional liner over one defect usually quotes $2,500 to $6,500. Cleaning, reinstated connections and access decide where a quote lands.
- A lining quote is mostly liner material, resin and specialised equipment; there is little excavation to pay for when a usable cleanout exists.
- Cleaning the host pipe properly is the step that decides whether the liner lasts, so it should be a priced line, not an afterthought.
- Every branch connection the liner covers must be reopened, and each one is usually priced separately.
- A liner follows the old pipe, so a sag, a collapse or a badly offset joint needs a different fix first.
01 /How much does it cost to line a sewer pipe?
Lining costs depend first on how much pipe is lined. A full-length liner from the house to the property line or the main is a replacement-scale job; a sectional liner over one cracked or root-infiltrated joint is a repair-scale job. The table shows typical 2026 quoted ranges for each, in Canadian dollars.
| Lining job | Typical range | Assumptions |
|---|---|---|
| Full lateral liner, 15–25 m | $9,000–$28,000 | Existing cleanout, 100 mm pipe, one or two connections |
| Per metre after setup | $500–$1,200 ($150–$365/ft) | Varies with diameter, liner thickness and cure method |
| Sectional (point) liner, one defect | $2,500–$6,500 | Short liner over a single defect, installed from a cleanout |
| Each extra section, same visit | $1,500–$3,500 | Mobilisation already covered |
| Pre-cleaning, root cutting or descaling | $400–$2,500 | Required before any liner goes in |
| Reinstating a branch connection | $300–$1,200 each | Robotic cutter working from inside the liner |
| Access pit where no cleanout exists | $1,500–$4,500 | Plus restoration above the pit |
| New exterior cleanout | $600–$2,500 | Often installed in the same pit |
Compared with digging, most of a lining budget moves from the shovel to the truck: resin, liner tube, inversion equipment, a heat or light source for curing and a robotic cutter. That is why lining looks expensive on an open lawn and cheap under a driveway. The broader method choice is covered in trenchless lining vs pipe bursting cost.
02 /What does a lining crew actually do?
A lining job is a sequence of preparation, installation and proof. Knowing the sequence helps you check that each step is priced in the quote rather than assumed.
- Camera and measure
The crew runs a camera to confirm length, diameter, connections and defects, and cuts the liner to length. Diameter changes, such as a 75 mm (3 in) section under the house meeting a 100 mm (4 in) lateral, must be identified at this stage.
- Clean the host pipe
Roots, grease and scale are removed by cutting, jetting or descaling until the wall is clean. A liner cured over debris bonds poorly and can wrinkle.
- Wet out the liner
A felt or fibreglass tube is saturated with resin, usually epoxy for residential laterals, in a quantity matched to the pipe volume.
- Invert or pull in the liner
Air or water pressure turns the tube inside out into the pipe from the access point, or the tube is pulled into place and inflated with a bladder.
- Cure
The resin hardens with ambient time, hot water, steam or ultraviolet light, depending on the system. Cure time is the window when you cannot use the drains.
- Reinstate and finish
A robotic cutter reopens any branch connections, the ends are trimmed and sealed, and a recorded camera run documents the finished pipe.
Each step is a place where a low quote can cut corners. The one most often skimped is cleaning, because it is slow and invisible once the liner is in. Ask the contractor to describe the cleaning method, and to show you footage of the cleaned pipe before the liner goes in.
03 /What line items belong in a lining quote?
A complete lining quote separates preparation, the liner itself and proof of the result. When two lining quotes differ by several thousand dollars, compare them line by line using the list below.
| Line item | What it should specify | Typical range |
|---|---|---|
| Mobilisation and setup | Equipment, locates if a pit is needed, site protection | $500–$2,000 |
| Pre-lining camera | Recorded run with distances; sometimes credited | $0–$400 |
| Cleaning and preparation | Method (root cutting, jetting or descaling) and number of passes | $400–$2,500 |
| Liner and resin, installed | Length, diameter, resin type, liner thickness, cure method | $500–$1,200 per metre |
| Reinstatements | Number of connections and how they are sealed | $300–$1,200 each |
| Access pit and restoration | Only when there is no usable cleanout | $1,500–$4,500 plus surface |
| Transitions and end seals | How the liner ends at the house and at the property line or main | Often included; confirm |
| Permit | Who pulls it and whether an inspection is needed | $100–$500 |
| Post-lining video | Recorded footage end to end, including every connection | Should be included |
Resin type and liner thickness define what you are buying, in the same way SDR defines PVC pipe. If a quote only says "trenchless liner", ask for both in writing. Inverted liners are commonly designed to an established practice such as ASTM F1216, and asking which standard the design follows is a fair question for any contractor.
04 /What pushes a lining quote up or down?
| Driver | Raises the price | Lowers the price |
|---|---|---|
| Access | No cleanout, so a pit must be dug | Exterior cleanout at the foundation |
| Host pipe condition | Heavy roots, thick scale, grease | Clean pipe needing one jetting pass |
| Connections | Several branches, or a shared lateral | One straight run with no branches |
| Diameter changes and bends | Transitions from 75 to 100 mm; bends over 45 degrees | Constant diameter, gentle bends |
| Length | Very short runs, where fixed costs dominate | Mid-length laterals of about 12–25 m |
| Cure conditions | Cold weather lengthening cure; hot water or steam needed | Mild weather allowing an ambient cure |
| City side | Liner extended to the main with a connection seal | Liner ends at the property line |
Pipe material matters mostly through cleaning. Vitrified clay with root masses at every joint needs aggressive cutting; cast iron with heavy tuberculation needs descaling down to sound metal; Orangeburg may be too deformed to line at all. Ask how the contractor will prepare your specific material, and whether the price changes if preparation takes longer than expected.
Short runs deserve a specific check. A 6 m lateral carries almost the same setup, cleaning and camera costs as a 20 m one, so its per-metre figure looks high. Convert every quote with the method in sewer line cost per foot before deciding a short-run lining price is out of line.
05 /Is a full liner or a sectional liner better value?
A sectional liner is better value when the camera shows one or two isolated defects in otherwise sound pipe. A full liner is better value when defects repeat along the run, because several sectional liners soon cost as much as one continuous liner and still leave the joints between them unsealed.
Illustrative example: a 14 m clay lateral with roots at four joints. Four sectional liners on one visit might quote $2,800 for the first and $1,800 for each of the next three, or $8,200, leaving the other joints open to future roots. A full liner at $800 per metre plus $1,500 setup and $900 of root cutting quotes about $13,600 and seals every joint. The extra $5,400 buys protection at the joints the camera has not flagged yet.
Whether that extra is worth it depends on the tree cover, the pipe's age and how long you plan to own the house. The sewer line repair cost guide covers the single-defect side of the decision.
06 /How do I check the quality of a lining job?
Check a lining job with the post-lining video and the paperwork. The video should run the full length and show a smooth, continuous liner with fully reopened connections; the paperwork should record exactly what was installed.
- Continuous liner, no gaps. The camera should travel end to end without meeting the old pipe wall anywhere inside the lined section.
- Wrinkles within reason. Small ripples at bends are common; folds that stand proud of the wall can catch paper and should be discussed before final payment.
- Reopened connections. Each branch should be cut back to its full opening, with a smooth edge that will not snag.
- Sealed ends. The liner ends at the house and at the far end should sit tight to the host pipe, with no step that traps debris.
- Records. Liner length, diameter, resin type, thickness, cure method and date belong on the invoice.
Hold the final payment until you have the recording. If you plan to rely on the warranty, keep the footage with it; it is the baseline any future claim will be measured against. Payment structures that do this are covered in paying for sewer repairs.
To price your own line, run the lining option in the sewer cost estimator, then request quotes that state the length, diameter, number of connections and access point from your camera report. Whether lining is the right method at all is covered in is trenchless sewer repair worth it.
FAQQuestions people ask
How much does it cost to reline a sewer pipe?
As a 2026 planning estimate, relining a full residential lateral in Canada typically quotes about $9,000 to $28,000 CAD, and a single sectional liner about $2,500 to $6,500. Access, cleaning and the number of connections move the price.
Is lining cheaper than replacing a sewer line?
Often, when a driveway, trees or landscaping sit over the pipe, because lining avoids most restoration. On a shallow line under open lawn, open-cut replacement can cost about the same or less.
How long does sewer pipe lining take?
Most residential lining jobs take one day on site, sometimes two when heavy cleaning or several reinstatements are needed. Drains are out of use during installation and cure, usually for several hours.
Can every sewer pipe be lined?
No. Lining needs a pipe continuous enough for the liner to pass and hold its shape. Collapsed sections, large offsets, sags and badly deformed Orangeburg usually need excavation or bursting instead.
Does lining make the pipe smaller?
Slightly. A liner a few millimetres thick reduces the inside diameter, but the smooth, jointless surface often carries flow well. For a standard 100 mm residential lateral this rarely causes problems.
What warranty comes with a sewer liner?
Terms vary widely by contractor and liner system. Ask for the written warranty, what it covers (liner, workmanship, connections), how long it runs and whether it transfers to a buyer.
