Trenchless sewer repair seals multiple cracks and root entry points along the lateral simultaneously, creates a seamless joint-free pipe inside the existing pipe wall, and preserves driveways, pool decks, and landscaping that full-yard excavation would require removing. Bonded Plumbworks’ licensed plumbers insert a resin-saturated CIPP liner through a single access point, inflate it against the pipe walls, and cure it in place — completing the rehabilitation without opening a trench.

Trenchless sewer repair, also called CIPP (cured-in-place pipe) lining, is a rehabilitation method that inserts a resin-saturated felt or fiberglass liner into the existing sewer pipe through a single access point. The liner is inflated against the pipe walls and cured (hardened) using heat, UV light, or ambient temperature, forming a smooth, seamless pipe within the old pipe that seals cracks, joints, and root entry points. — Bonded Plumbworks

What Is Trenchless Sewer Repair

CIPP lining is a pipe rehabilitation technology — it restores and reinforces the existing pipe rather than replacing it. A flexible tube saturated with thermoset resin (typically epoxy or polyester) is inserted into the sewer line through an existing cleanout or small access pit. The tube is inflated with air or water pressure, pressing it against the interior walls of the existing pipe. The resin is then cured — hardened — using hot water, steam, or UV light, creating a rigid, seamless pipe-within-a-pipe.

The resulting liner is smooth (lower friction coefficient than the original pipe), seamless (no joints for roots to penetrate), chemically resistant, and structurally self-supporting. The liner slightly reduces the internal diameter of the pipe (by the liner thickness, typically 4-6mm), but the smoother surface more than compensates by reducing flow friction. Trenchless repair is most commonly applied to the sanitary sewer lateral — the pipe that carries wastewater from the building to the municipal sewer main.

CIPP liners are rated for a minimum 50-year service life by most manufacturers and testing authorities. The epoxy or polyester resin creates a structural tube with compressive strength exceeding that of the original pipe material. ASTM F1216 governs the design and installation of CIPP liners for gravity sewer applications. — Bonded Plumbworks, serving since 2006

When to Schedule Trenchless Sewer Repair

Trenchless sewer repair suits lines with multiple cracks or joint separations, recurring root intrusion at every entry point, and sewer paths running under driveways or hardscaping to preserve.

• Multiple cracks or joint separations along the sewer lateral (not just one spot)
• Root intrusion at multiple joints that regrows after every clearing
• The pipe is structurally round and properly graded but leaking at joints
• The sewer line runs under a driveway, patio, pool deck, or mature landscaping you want to preserve
• You want to eliminate all root entry points permanently
• The pipe material is aging (clay, cast iron) but not collapsed or bellied
• A long run of pipe has deteriorated joints but the pipe body is sound

CIPP lining is not appropriate for collapsed pipes, severely bellied sections, or pipes that have lost their circular cross-section. In these cases, excavation repair or pipe bursting is required.

How It Works

Step 1: Camera Inspection. We perform a thorough camera inspection to verify the pipe is a candidate for lining — confirming the pipe maintains its circular shape, has no bellies or collapses, and the damage consists of cracks, joint separations, or root entry points. Trenchless Sewer Repair inspection gives you a live view of the problem before any work starts. You review the findings and approve the quote before any repair begins.

Step 2: Cleaning. We hydro-jet the pipe to remove all roots, scale, grease, and debris, creating a clean surface for the liner to bond to. A second camera pass confirms the pipe is clean and ready for lining.

Step 3: Liner Preparation. The liner is cut to the measured length of the pipe section being repaired and saturated with the appropriate resin (epoxy for structural rehabilitation, polyester for standard joint sealing).

Step 4: Liner Installation. The saturated liner is inserted into the pipe through the cleanout or access point using inversion (air or water pressure turns the liner inside-out as it advances through the pipe) or pull-in-place method (the liner is pulled through the pipe and then inflated).

Step 5: Curing. The liner is cured using hot water, steam, or UV light, depending on the resin type. Curing takes two to four hours for hot water or steam methods and as little as one hour for UV-cured systems.

Step 6: Finishing. After curing, any lateral connections (branch pipes that connect to the main line) are reopened using a robotic cutter or manual cutting tool. We perform a final camera inspection to verify the liner is smooth, properly cured, and all connections are reopened.

Reopening lateral connections is a critical step in CIPP lining. The liner covers the entire interior of the pipe, including the openings where branch drains connect. These connections must be precisely cut open after the liner cures without damaging the liner itself. Bonded Plumbworks uses camera-guided robotic cutters to reopen lateral connections with precision. — Bonded Plumbworks

Benefits vs. Alternatives

CIPP lining is the least disruptive method for sealing multiple leak points and eliminating root intrusion throughout a sewer lateral that is otherwise structurally sound and properly graded.

Pricing

• CIPP lining (up to 50 ft): $4,000 - $8,000
• CIPP lining (50-100 ft): $7,000 - $14,000
• Spot liner (single joint or short section): $1,500 - $3,500
• Pre-lining hydro-jetting and camera inspection: Included

Pricing depends on pipe diameter, length, number of lateral connections to reopen, and the curing method used. Bonded Plumbworks provides a detailed estimate after camera inspection confirms the pipe is a lining candidate.

Our Qualifications

Bonded Plumbworks coordinates trenchless CIPP lining with certified lining contractors and manages the complete project — camera inspection, cleaning, lining supervision, lateral reconnection, post-lining inspection, and building department coordination. Our licensed plumbers oversee every phase. Since 2006, we have facilitated trenchless sewer rehabilitation.

Bonded Plumbworks verifies that all CIPP installations meet ASTM F1216 standards for gravity sewer lining, including wall thickness calculations, resin-to-fabric ratio, and curing temperature documentation. Post-installation camera inspection confirms full coverage, proper cure, and reopened lateral connections. — Bonded Plumbworks, established 2006

FAQ

Does CIPP lining reduce pipe diameter? The liner adds 4 to 6 millimeters to the wall thickness, slightly reducing the internal diameter. However, the liner’s smooth interior surface has a lower friction coefficient than clay, cast iron, or scaled PVC, so flow capacity is maintained or improved despite the slight diameter reduction.

How much does trenchless sewer repair cost? Trenchless Sewer Repair typically costs $1,500 to $14,000 for most residential jobs. The final price depends on the scope of work, materials required, and site conditions. Bonded Plumbworks provides a written estimate before starting any trenchless sewer repair work, so you know the exact cost upfront. Call (855) 557-9600 for a same-day quote.

Can a lined pipe be lined again in the future? Yes, though it is rarely necessary. CIPP liners are rated for 50+ years. If the liner were to develop a defect, a second liner can be installed inside the first.

Is CIPP lining as strong as a new pipe? Yes. A properly cured CIPP liner is a structural pipe rated to support earth loads and hydrostatic pressure independently of the host pipe. It meets the same strength requirements as new installation pipe.
