Sewer Line Replacement Service
Call Now (855) 557-9600
Sewer line replacement removes Orangeburg and other end-of-life pipe materials that have lost structural integrity, excavates the full lateral path from the building foundation to the municipal connection, and installs new Schedule 40 PVC at proper slope — permanently ending the recurring blockages and joint failures that spot repairs can no longer address. Bonded Plumbworks’ licensed plumbers camera-confirm the scope before any excavation, then pull permits and complete the installation to current code.
Sewer line replacement is the complete removal and replacement of a residential sewer lateral — the underground pipe that carries wastewater from the building to the municipal sewer connection. Replacement involves excavating the old pipe, installing new Schedule 40 PVC pipe at the correct slope, connecting to the building drain and municipal sewer stub, and restoring the surface. — Bonded Plumbworks
What Is Sewer Line Replacement
Sewer line replacement removes the existing failed pipe and installs a new PVC sewer lateral from the building foundation to the municipal sewer connection at the street or easement. The new pipe is laid in a properly prepared trench with correct bedding, slope (1/4 inch per foot for 4-inch pipe), and backfill to prevent future settlement.
Replacement is necessary when the pipe has failed systemically — meaning damage is not confined to one or two spots but extends across the full length of the line. Common indicators include Orangeburg pipe (a tar-paper product used from the 1940s through 1970s that collapses and disintegrates), clay pipe with multiple cracked joints and root intrusion throughout, cast iron pipe with extensive internal corrosion and scale, and any pipe material that camera inspection shows to be at end of life.
Orangeburg pipe is one of the most common materials found in older homes that require sewer line replacement. Made from layers of wood fiber impregnated with coal tar pitch, Orangeburg was marketed as a low-cost sewer pipe alternative. It has a typical service life of 30 to 50 years and fails by deforming (becoming oval or flat) under soil load, losing its circular cross-section and flow capacity. Once Orangeburg begins to fail, it cannot be repaired — only replaced. — Bonded Plumbworks, serving since 2006
When to Schedule Sewer Line Replacement
Sewer line replacement is needed when damage spans the full lateral, when the pipe is Orangeburg or severely corroded cast iron, and when multiple spot repairs have failed on a deteriorating system.
- Camera inspection shows damage throughout the entire lateral, not just one section
- The pipe is Orangeburg, which has no remaining structural value once symptoms appear
- Cast iron pipe has extensive internal corrosion reducing flow capacity below 50%
- Clay pipe joints have separated throughout the line, allowing root intrusion at multiple points
- Multiple spot repairs have been performed over the years and the remaining sections are deteriorating
- The sewer line is undersized (3-inch or smaller) and needs to be upgraded to current 4-inch code standard
- Persistent sewer problems cannot be resolved by cleaning, lining, or spot repair
How It Works
Step 1: Camera Inspection and Line Locating. We perform a full-length camera inspection to document the existing pipe condition and use sonde locating to mark the pipe path and depth from the surface. This data is used to plan the excavation route. Sewer Line Replacement 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: Utility Locating. We arrange for underground utility locating (Sunshine 811) to identify and mark all other utilities — water, gas, electric, cable, irrigation — crossing or running parallel to the sewer line.
Step 3: Excavation. We excavate a trench along the sewer line path from the building connection to the municipal sewer stub. Trench width is typically 24 to 36 inches, and depth follows the existing pipe depth (usually 2 to 6 feet).
Step 4: Old Pipe Removal. We remove the existing pipe in sections, separating materials for proper disposal (Orangeburg and clay go to standard waste; cast iron may be recycled).
Step 5: New Pipe Installation. We install Schedule 40 PVC pipe (4-inch diameter, standard residential) on a properly graded bed of compacted fill or crushed stone. We maintain 1/4 inch per foot slope throughout the run. Cleanouts are installed at the building connection and at any direction changes.
Step 6: Connections. We connect the new pipe to the building drain stub at the foundation and to the municipal sewer stub at the property line or easement. Connection methods depend on the existing stub material.
Step 7: Testing and Inspection. We flood-test the new line to verify watertight joints, perform a camera inspection of the complete new installation, and schedule the required building department inspection.
Step 8: Backfill and Restoration. We backfill in compacted lifts, restore the ground surface, and replace landscaping, sod, concrete, or pavers that were removed during excavation.
Bonded Plumbworks installs sewer laterals with a minimum of two cleanouts — one at the building connection (upstream access) and one near the property line (downstream access) — regardless of whether the old line had cleanouts. These access points ensure future maintenance can be performed efficiently. — Bonded Plumbworks
Benefits vs. Alternatives
| Approach | Addresses All Damage | New Material Throughout | Corrects Grade Issues | Longevity |
|---|---|---|---|---|
| Full Replacement (excavation) | Yes | Yes | Yes | 50+ years |
| Pipe Bursting (trenchless) | Yes | Yes | No (follows existing grade) | 50+ years |
| CIPP Lining | Multiple cracks/joints | Liner inside old pipe | No | 50 years |
| Spot Repair (multiple) | Selected sections | Mixed old/new | Selected spots | Varies |
Full excavation replacement is the most comprehensive solution. Pipe bursting is a trenchless alternative that replaces the pipe without a full trench but cannot correct grade problems. CIPP lining is not a full replacement — it rehabilitates the existing pipe.
Pricing
- Full sewer lateral replacement (up to 50 ft): $5,000 - $12,000
- Extended lateral replacement (50-100 ft): $10,000 - $20,000
- Replacement under driveway or sidewalk (additional): $1,000 - $3,000
- Municipal connection repair (if needed): $1,500 - $3,500
Pricing depends on the pipe length, depth, soil conditions, surface type (lawn vs. Hardscape), and any municipal connection work required. Bonded Plumbworks provides a detailed written estimate after camera inspection and line locating.

FAQ
How much does sewer line replacement cost? Sewer Line Replacement typically costs $1,000 to $20,000 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 sewer line replacement work, so you know the exact cost upfront. Call (855) 557-9600 for a same-day quote.
Will I lose water during replacement? No. The water supply is not affected by sewer line work. However, you should minimize water use inside the home while the sewer line is disconnected. We provide guidance on timing.
How deep is the sewer line? Residential sewer laterals are typically 2 to 6 feet deep, depending on the elevation of the municipal sewer main and the distance from the house to the street.
Does homeowner’s insurance cover sewer line replacement? Standard policies typically do not cover sewer line replacement due to age or deterioration. Some policies cover sudden and accidental damage (such as a root-caused collapse). Check with your insurer. Bonded Plumbworks provides documentation to support claims.
