How CIPP works
A resin-saturated felt sleeve is pulled or inverted into the old pipe, then cured — with hot water, steam, or UV light — into a hard, smooth, jointless pipe inside the host. Because it needs only an access point or two (often the existing cleanout), there’s no trench along the run. The new liner is seamless, so it also seals the joints where roots used to enter.
What drives the price
Length and diameter set the base. Bends and transitions add difficulty. Access — whether the crew can work from an existing cleanout or must dig a pit — matters, as does the resin system (UV cure is faster but pricier). The savings show up on the other side of the ledger: no surface restoration.
When lining is (and isn’t) the answer
Lining is ideal when the host pipe is cracked, root-infiltrated, or leaking but still structurally present. It is not an option for a collapsed, badly offset, or severely bellied line — that needs pipe bursting or an open-cut replacement. A camera inspection decides which camp you’re in, and the repair calculator compares all three methods side by side.
If the cause is covered, you may not owe the whole bill — check the coverage verdict first.
Common questions
How much does CIPP pipe lining cost?
CIPP lining runs about $80–$250 per foot, so a typical 50–100 ft residential lateral lands around $4,000–$20,000 installed. Diameter, the number of bends, access, and the resin system all move the figure; the payoff is little to no surface restoration.
Is CIPP lining cheaper than digging?
Per foot, no — lining costs more than open-cut pipe work. All-in, it frequently wins because there is no trench to backfill and no driveway, patio, or lawn to rebuild. On a line under hardscape or deep in the yard, relining is usually the cheaper and far less disruptive choice.
How long does CIPP lining last?
A properly installed cured-in-place liner is rated for roughly 50 years — comparable to a new pipe. The resin sleeve hardens into a smooth, jointless pipe inside the old one, which also resists root intrusion at the former joints.
Can any pipe be lined?
No. The host pipe must be intact enough to line — a collapsed, badly offset, or severely bellied line can’t be, and needs pipe bursting or an open-cut replacement instead. A camera inspection is what determines whether lining is an option.
Does insurance cover CIPP lining?
Only if the cause of the failure is covered — the common causes (roots, age, corrosion) are excluded on a standard policy unless you carry a service-line endorsement. The repair method doesn’t change the coverage; the cause does.
