Cured-in-Place Pipe (CIPP) Lining
Cured-in-place pipe lining inserts a resin-saturated felt sleeve into your existing sewer line, then hardens it with heat, steam, or UV light — forming a smooth, jointless new pipe inside the old one. It seals cracks and blocks roots with minimal digging. FlowFast connects you with an independent local plumber who can assess whether your line is a lining candidate.

Sewer Line Repair & ReplacementSewer line problems? Trenchless vs. traditional replacement, warning signs, and how to get connected with an independent local plumber for sewer work.
View all Sewer Lines servicesCIPP is the least invasive way to rehabilitate a damaged sewer line. After the old pipe is thoroughly cleaned — usually by hydro jetting — a flexible liner soaked in epoxy resin is inverted or pulled into place through a cleanout or small access point. The liner is then cured: hot water, steam, or UV light hardens the resin into a rigid, seamless tube bonded to the inside of the old pipe. The result seals cracks, bridges missing sections, and eliminates the joints where roots entered, all without opening a trench across your property.
Lining has real limits worth knowing. It needs a host pipe intact enough to hold the liner's shape — fully collapsed sections cannot be lined. It slightly reduces the pipe's inner diameter, and it cannot correct a belly, since the liner follows the existing sag. The old line must also be meticulously cleaned first, or the liner bonds to debris instead of pipe. FlowFast Plumbing is a referral service — we connect you with an independent local plumber who can camera your line and give you a straight answer on whether CIPP fits.
Warning signs
Signs you need this service
- A camera inspection showed cracks, joint separations, or root intrusion in a pipe that is still structurally holding its shape.
- You want the line rehabilitated with the least possible digging — lining often needs only existing cleanout access.
- The line runs beneath expensive hardscaping, additions, or mature trees that make any excavation painful.
- Multiple joints are leaking along a run, and lining them all at once beats repairing each joint individually.
What to expect
The process, step by step
The pro cameras and thoroughly cleans the line — usually with hydro jetting — since the liner must bond to clean pipe.
The resin-saturated liner is inserted through a cleanout or access point and positioned across the damaged section.
The liner is cured with heat, steam, or UV light, hardening into a rigid, jointless new pipe inside the old one.
A post-installation camera inspection verifies the liner's placement and flow, and lateral connections are reinstated robotically if needed.
Prevention
How to avoid this problem
- Keep roots from re-entering at connection points — the liner seals the run, but joints at either end stay vulnerable.
- Avoid harsh chemical drain cleaners, which can damage resin liners over time; use mechanical cleaning instead.
- Schedule a follow-up camera inspection in a few years to confirm the liner and the remaining original pipe are sound.
