Cracks and fractures
Clay, cast iron and other older materials may crack as soil shifts or the pipe deteriorates.
No dig. No destruction.
A new sewer pipe—inside the one you already have.
Cal Flow Repipe restores cracked, root-damaged and aging residential sewer mains from the inside using trenchless pipe-lining technology—without tearing through your driveway, landscaping or floors.

Inside an aging sewer main
What a 40-year-old line may look like today
Age alone does not determine whether a pipe needs relining or replacement. A camera inspection may reveal several defects that explain recurring backups, slow drains or root problems.
Root intrusion
Roots enter through joints and openings, then trap waste and cause repeated blockages.
Scale and corrosion
Rough internal surfaces reduce flow and make the line more likely to collect debris.
Offset joints
Separated sections can leak, snag solids or allow soil and groundwater into the line.
Choose the right repair
Why homeowners often prefer relining to replacement
Relining rehabilitates the pipe from within. Traditional replacement usually requires access by excavation and then repair of the disturbed property.
Trenchless relining
Best when the host pipe still has a usable path and can be properly cleaned and prepared.
- Minimal digging and property disturbance
- Preserves driveways, patios and landscaping
- Creates a smooth, continuous interior
- Reduces joints where roots commonly enter
- Often shortens the overall project
Excavation and replacement
May be necessary when the existing pipe cannot support or receive a liner.
- Trenching or slab access may be required
- Concrete and landscaping restoration can add cost
- More disruption, equipment and debris
- May take longer depending on site conditions
- Appropriate for collapse, severe deformation or grade failure
Honest qualification: relining is not the correct solution for every line. Fully collapsed sections, severe offsets, major bellies or poor grade may require spot repair, pipe bursting or conventional replacement.
How it works1 2 3 4
From camera inspection to restored flow
Inspect
We review camera footage and verify the location and type of damage.
Clean
Roots, scale and buildup are removed so the liner can bond correctly.
Install
A resin-saturated liner is positioned inside the existing sewer route.
Cure and verify
The liner hardens into a new pipe, followed by final camera inspection.
Homeowner questions
Before you decide
A proper recommendation depends on pipe material, access, length, diameter, cleaning results and the actual camera findings.
Can every old sewer line be relined?
No. The line must have a usable pathway and enough structural continuity for cleaning and liner installation.
Will relining stop tree roots?
A continuous liner seals many cracks and joints where roots enter. Existing roots must be removed and the connection points must be properly finished.
Does relining reduce the pipe diameter?
The liner slightly reduces internal diameter, but its smoother surface can improve flow compared with a rough, scaled or root-damaged pipe.
