This is the question everyone actually wants answered, and it is the one most contractors dodge. Here is the honest version: lining is priced per foot, the range is wide because the variables are real, and the only number that means anything is the one that comes after somebody has looked inside your pipe.
What we can do usefully is explain exactly how the number is built, so you can read a quote properly and tell whether two of them are even describing the same job.
Why it is priced per foot
Liner material, resin volume and installation labour all scale directly with the length of the run. A 25-foot lateral and an 80-foot lateral are not the same job, and a single lump sum hides that.
Per-foot pricing has a second advantage for you: it makes competing quotes comparable. If one contractor quotes per foot and another quotes a flat figure with no breakdown, ask the second one to itemise. What you learn from the answer is usually more useful than the number.
The six things that move the price
- Length of the run — the primary driver, and the reason per-foot pricing exists.
- Depth — a lateral four feet down is a different job from one at twelve, particularly where access pits are needed.
- Whether there is an accessible cleanout — without one, access has to be created first, and that is additional work.
- Pipe condition — heavily scaled cast iron needs mechanical descaling before lining, which is a separate operation from jetting.
- Number of branch connections — each one has to be reinstated after the cure.
- What is on the surface — this is where trenchless earns its keep, because it is the line item open-cut cannot avoid.
What a complete quote includes
The most common way a lining quote comes in artificially low is by leaving things out that will happen anyway. Before you compare two numbers, check both include:
- The pre-lining camera inspection and locate
- Cleaning and descaling of the host pipe
- The liner itself, specified to your pipe’s diameter and length
- Reinstatement of every branch connection
- Post-cure camera verification, with footage provided
- WSSC permitting where the work requires it
- Site cleanup and any surface restoration at access points
Comparing trenchless against open-cut properly
The comparison people make is plumbing versus plumbing. The comparison that determines what you actually pay is total project versus total project.
Take a sixty-foot lateral running under a section of driveway, across lawn, past two mature trees. The open-cut quote covers excavation and pipe. It does not cover repouring the driveway section, re-turfing the trench, replacing the plantings that were in the way, or the tree if the trench went through its root plate.
On that property, restoration can equal or exceed the plumbing. On a property where the line runs under open lawn with nothing above it, the two methods are genuinely competitive and we will say so.
Getting a number you can rely on
Our estimates are free, and for sewer line work the camera inspection that informs the estimate is included when you proceed with the repair. The quote is flat-rate: the figure you are given before work starts is the figure you pay.
If we open something up and find a genuinely different problem from the one diagnosed, we stop and re-quote before continuing. We do not add to an agreed price without your approval.
