Step 1
Camera-locate the defect precisely
A high-resolution sewer camera locates the defect to the foot and determines its length, width, and pipe diameter. This footage drives the spot liner specification.

Spot Lining that seals one problem without touching the rest
Spot lining (also called a CIPP patch) places a short cured-in-place liner precisely over a single defect in your sewer line. When the rest of the pipe is in good shape and only one section needs repair, a spot liner is faster, less disruptive, and less expensive than a full-run CIPP install.

COMMON REASONS
When Spot Lining Is the Right Call
Spot lining is the targeted repair for a single, camera-confirmed defect. Four situations point to a spot liner over a full-run CIPP install.
Common Spot Lining situations:
Spot lining for a single root-entry crack
When camera footage shows one crack or joint gap where roots are entering (and the rest of the line is in good shape), a spot liner seals that entry point without lining the full run.
Spot lining for a single offset or crack
A pipe offset or fracture at one location can be patched precisely with a spot liner. No need to line 60 feet of pipe when only 18 inches are defective.
Spot lining for a single joint failure
A joint that has crumbled or separated at one point in an otherwise sound line is an ideal spot liner case. The patch bonds to both sides of the joint and closes the gap where roots and water were entering.
Spot lining as a cost-effective targeted repair
When a full camera scope shows one isolated defect and the balance of the line is structurally sound, a spot liner is the right-sized solution: less time, less cost, and comparable results to a full-run liner.
WHAT TO WATCH FOR
Signs a Spot Liner Is the Right Fit
An isolated defect can spread if left alone. Here are four signs that a spot liner is worth discussing at your next camera inspection.
Watch for these Spot Lining triggers:
- A camera scope showing one isolated defectWhen the camera finds a single crack, root gap, or joint failure in an otherwise clean line, that is the exact use case for a spot liner.
- Roots returning at the same location annuallyIf annual camera scopes show roots re-entering through the same 12-inch section every year, a spot liner seals that entry point, and roots cannot penetrate cured resin.
- A single offset causing recurring partial blockagesA pipe offset that catches debris and creates recurring partial blockages is efficiently addressed with a spot liner that bridges the offset without replacing the full run.
- A targeted repair that protects the rest of the investmentWhen you have had a full-run CIPP liner installed and a single joint shows stress years later, a spot liner extends the system without replacing the entire liner.
SERVICE PROCESS
How Our Spot Lining Process Works
Precision is everything in spot lining. Four standards make every LiningWorks spot liner accurate and durable.
Spot Lining starts with a targeted camera scope
We locate the defect precisely by camera before the liner is prepared. The exact position, length, and pipe diameter determine the spot liner specification.
Spot Lining requires a clean pipe wall at the defect
We hydro-jet the section around the defect to ensure the liner bonds to clean pipe wall on both sides. Even a small area of grease or root debris compromises the bond.
Spot Lining uses a resin-saturated short liner tube
The spot liner is a short CIPP tube (typically 12 to 36 inches) saturated with resin and sized to overlap the defect by at least four inches on each side.
Spot Lining is verified by camera at the defect location
After the spot liner cures, a camera confirms the patch is fully seated and bonded. You see the repaired section on screen before we close out the job.
SIMPLE PROCESS
The Spot Lining Process, Step by Step
Same precise sequence on every spot liner job, whether the patch is over a 12-inch crack or a 36-inch joint gap.
Step 2
Hydro-jet the defect area so the liner bonds cleanly
We jet the pipe wall at and around the defect location. The resin liner must bond to clean pipe material; even minor contamination at the defect edge compromises the seal.

Step 3
Prepare and saturate the short spot liner tube
We cut and saturate a short CIPP tube sized to overlap the defect by at least four inches on each side. The resin is mixed fresh on site.
Schedule a consultation Step 4
Place the spot liner precisely over the defect
Using a placement tool, we position the saturated liner exactly over the defect and inflate it under controlled pressure against the host pipe wall on both sides.
Schedule a consultation
Step 5
Cure and verify the spot liner with a final camera pass
The spot liner cures under pressure. Once cured, a camera confirms the patch is fully sealed at the defect. You see the repair on screen and keep the verification video.

BEFORE & AFTER
Spot Lining Fixed: A Belmont Home, One Root-Entry Crack in an Otherwise Sound Line
Annual camera scopes kept showing root intrusion at the 31-foot mark. The rest of the 58-foot line was structurally sound. LiningWorks placed a 24-inch spot liner over the crack in a single two-hour visit, and the verification scope confirmed full closure at the defect.
Spot lining is the right call when the camera confirms one isolated defect. There is no reason to line 58 feet when only 24 inches are defective. One targeted patch, one flat price, problem solved.
