Sewer Line Repair Cost

Not every sewer problem needs a new line. Roots, a single crack or a clog can often be fixed in one spot. Angi puts the average sewer line repair at about $2,600, with most jobs between $1,100 and $4,100.

Cost by problem

Inspection first

A camera inspection shows where the damage is and how long it runs. Angi lists it at $300 to $400, HomeAdvisor at $100 to $500 and HomeGuide at $125 to $500. Ask for a copy of the video; it helps when comparing quotes.

Repair methods

• Spot repair. Digging down to one damaged section and replacing it.
• Pipe lining (CIPP). A resin liner is cured inside the old pipe, creating a new pipe within it: $80 to $250 per foot (Angi).
• Pipe bursting. A new pipe is pulled through while the old one is broken apart: $60 to $200 per foot (Angi).

If damage runs along much of the line, a full replacement can cost less per foot than several repairs. Compare with sewer line replacement cost.

Signs of sewer line trouble

• Several drains backing up at the same time, especially lower-level ones.
• Gurgling toilets or drains.
• Sewage odors indoors or in the yard.
• Unusually green or soggy patches of lawn above the line.

Clearing a clog

If the problem is a blockage rather than damage, cleaning may be enough. Snaking a main line costs $100 to $400 (Angi), while hydro jetting costs more but clears grease and roots more thoroughly.

Common sewer line problems

• Root intrusion through joints in clay or cast iron pipe.
• Bellies, where a section of pipe has sagged and holds water and waste.
• Cracks and breaks from age, soil movement or heavy loads.
• Offset joints, where sections have shifted out of line.
• Corrosion in older cast iron pipe.

How plumbers find the problem

A camera inspection through a cleanout shows the type and location of the damage and how deep the pipe is. Many plumbers also use a locator to mark the problem spot on the surface so excavation is kept to a minimum.

More on repair methods

• Spot repair. Dig down to the damaged section and replace it. Practical when the damage is limited.
• Pipe lining (cured-in-place). A resin-soaked liner is inserted and cured inside the old pipe, creating a new pipe within it without major digging.
• Pipe bursting. A new pipe is pulled through the old one while breaking it apart; requires access pits at each end.
• Full replacement. Trenching and replacing the whole line, usually when damage runs the full length.

What affects the price

Depth of the pipe, length of the damaged section, what sits on top of it (lawn, driveway, landscaping), the repair method, and permit requirements all change the cost. Repairs under a slab or a driveway are the most expensive.

Questions to ask

1. Can I see the camera footage and the location of the damage?
2. Is a spot repair enough, or is the rest of the line likely to fail soon?
3. Does the price include restoring the yard or driveway?

In Texas

Expansive clay soil in much of Texas swells and shrinks with moisture, which can shift and crack underground pipes. Combined with older clay and cast iron sewer lines and mature trees, this makes sewer line problems common in older Texas neighborhoods.

What a camera inspection report should show

A good sewer camera inspection gives you more than a verbal summary. Ask for the video file and a written report that notes the distance from the cleanout to each problem, the type of pipe, and what the camera found: roots, cracks, offsets at the joints, sags (bellies) holding water, or a full collapse. Many systems also have a locator that marks the problem spot on the ground, which shows whether the defect is under the yard, the driveway or the house.

With that information, you can get repair quotes from more than one company based on the same facts. Without it, each company would need to inspect again.

Matching the repair to the problem

Roots at one joint. Often solved with a spot repair, or by cleaning and installing a short liner at that joint.

A belly in the line. Water and waste collect in the low spot and cause repeat clogs. The section usually needs to be dug up and relaid on a proper grade. Lining does not fix a sag.

Cracked or corroded pipe along much of the line. Lining or full replacement makes more sense than chasing individual repairs.

A collapsed section. Usually requires excavation at that spot, because a camera or liner cannot pass through.

Who is responsible for which part

In most cities, the homeowner is responsible for the sewer lateral from the house to the property line or to the connection with the city main, while the city maintains the main itself. The exact dividing point varies, so check with your city's utility department. If the problem is in the city's section, the city should repair it at no cost to you. A camera inspection that measures the distance to the problem helps settle that question.

Permits and right-of-way work

Digging in a sidewalk, street or easement usually requires a permit and sometimes a separate contractor approved by the city. These costs can be significant and are often not in the first quote. Ask the plumber whether the repair point falls inside or outside your property line.

Insurance and service line coverage

Standard homeowners policies often exclude sewer line repairs caused by wear, roots or settling. Some insurers and utilities offer service line coverage as an add-on for a small yearly fee. If you have an older home with clay or cast iron pipe, it may be worth comparing the cost of coverage with the cost of a single repair.
