Sewer Line Repair and Replacement
Your home's sewer line is the single pipe — typically 4 to 6 inches in diameter — that carries all wastewater from your home to the municipal sewer system or septic tank. When this line fails, it affects every drain and toilet in the house simultaneously. Sewage backup is a serious health hazard, and sewer line problems do not resolve on their own.
Plumbing Crew USA connects you with licensed sewer specialists who perform camera inspections, trenchless repairs, and traditional excavation repairs — choosing the method that solves your problem with the least disruption to your property.
Common Sewer Line Problems
- Tree root intrusion: The most common cause of sewer line blockages in the US. Roots follow the moisture gradient, entering pipes through joints and cracks, then growing into dense root masses that completely block flow.
- Grease and debris buildup: Over time, grease accumulates on pipe walls, trapping solids and progressively narrowing the pipe bore.
- Pipe collapse or bellying: Sections of pipe can sag (belly) due to soil movement or improper installation, creating low spots where solids accumulate and flow is blocked. Severe bellying leads to full collapse.
- Corrosion: Cast iron and clay pipes are prone to corrosion. Hydrogen sulfide gas generated by decomposing waste accelerates deterioration from inside.
- Offset or separated joints: Ground movement, soil settling, and frost heave can shift pipe sections out of alignment.
- Infiltration and inflow: Groundwater entering cracked pipes can overwhelm the system and carries soil that causes further damage.
Warning Signs of Sewer Line Failure
- Multiple drains backing up simultaneously throughout the house
- Raw sewage smell inside or around the home
- Gurgling toilets when running sinks or the dishwasher
- Sewage backing up into the lowest floor drains or toilets
- Unusually lush or green patches in the yard (sewage acting as fertilizer)
- Indentations or sinkholes developing in the yard
- Persistent drain clogs that return despite cleaning
Our Sewer Repair Methods
CCTV Camera Inspection: Before any repair, we run a high-definition waterproof camera through the line to identify the exact problem, location, and severity. This prevents guesswork and unnecessary excavation.
Hydro-Jetting: High-pressure water cutting at up to 4,000 PSI removes root masses, grease, and debris. Often used as a first step before trenchless repair to clear the line.
Pipe Lining (CIPP — Cured-In-Place Pipe): A flexible liner saturated with epoxy resin is inserted into the existing damaged pipe. Once inflated and cured, it forms a seamless new pipe within the old one. No excavation required for accessible sections. Extends pipe life by 50+ years.
Pipe Bursting: A bursting head is pulled through the old pipe, fracturing it outward while simultaneously pulling a new HDPE pipe into position. Requires only small entry and exit pits rather than full trench excavation.
Traditional Excavation: When pipe damage is severe, collapse is complete, or trenchless methods aren't feasible, we excavate to fully replace the damaged section. Always the last resort due to landscape disruption.
Sewer Line Repair Costs
- Camera inspection: $150–$400
- Hydro-jetting: $300–$800
- Pipe lining (per foot): $80–$250/ft (typical job: $3,000–$8,000)
- Pipe bursting: $60–$200/ft (typical job: $2,500–$7,000)
- Traditional excavation and replacement (per foot): $50–$250/ft
Is Sewer Line Repair Covered by Insurance?
Standard homeowner's insurance typically does not cover sewer line repair — it's considered part of the structure maintenance responsibility. However, many insurers offer an affordable sewer line insurance rider. Some municipalities offer sewer line protection programs. Always check with your insurance agent before a problem occurs, not after.
Typical cost range: $500–$3,000. Prices vary by location and severity. Call for an upfront quote.
Frequently Asked Questions
How do I know if I have a sewer line problem?
Signs of a main sewer line problem: multiple drains backing up simultaneously, gurgling sounds from drains when other fixtures are used, sewage odor inside the home, wet spots or unusually lush grass over the sewer line path in the yard, or a water meter that moves when all fixtures are off. Any of these warrants a professional assessment — sewer line problems don't resolve on their own.
How much does sewer line repair or replacement cost?
Sewer line cleaning: $150–$350 for snaking, $250–$600 for hydro jetting. Camera inspection: $100–$300. Spot repair of a specific damaged section: $500–$2,000 depending on depth and access. Full sewer line replacement with excavation: $3,000–$25,000 depending on line length, depth, and soil conditions. Trenchless lining: $3,000–$15,000 depending on line length.
What causes sewer backups?
Common causes: tree root infiltration through sewer line joints, grease and debris accumulation narrowing the pipe, pipe sag creating a low point where solids accumulate, collapsed or offset sections of older pipe, and municipal sewer system overload during heavy rain events. In older homes with clay tile or cast iron lines, structural deterioration at joints is a primary cause. Camera inspection identifies the specific cause.
What is a sewer backup preventer or backwater valve?
A backwater valve is a one-way valve installed in the main drain line that allows sewage to flow out normally but prevents sewage from flowing back into the home during municipal sewer backups. It's one of the most effective flood prevention measures for homes in low-lying areas or areas prone to sewer surcharge events during heavy rain. Installation requires a plumber and typically involves concrete cutting.
