How Much Does Sewer Line Repair Cost in Tennessee?

Most full sewer line replacements cost about $1,390 to $5,320, according to national cost guides. Their average sits near $3,300. One guide puts a spot repair on a single cracked section at $600 to $1,050.

Long runs cost more, and so do lines under concrete. One national guide puts an 80-foot replacement at $4,000 to $20,000. These are market numbers, not our price list.

What do sewer line repairs cost, job by job?

These ranges come from national cost guides. Local conditions decide where a Middle Tennessee job lands.

One guide puts the average replacement near $150 per foot, with materials and labor included. Root removal and a spot repair cost far less than a new line. That gap is why finding the exact problem matters.

How does the length of the line change the price?

Replacement is often priced by the foot, so length sets the starting point. One national guide reports these totals for a full replacement:

The same guide says most full replacements run about 40 feet. Partial repairs may cover only 1 to 15 feet, so they cost less.

Should you repair the sewer line or replace it?

Repair makes sense when one section is bad and the rest of the pipe is sound. A single crack or one joint full of roots often needs only a spot repair.

Replacement makes more sense when the pipe fails in several places. National cost guides point to a collapsed pipe or one with the wrong slope. Backups that return after every cleaning point the same way.

A clog that clears and stays clear is a drain cleaning job. A clog that keeps coming back often points to damage in the pipe itself.

What else moves the cost of a sewer line repair?

These factors move a job up or down.

• Depth. Deeper pipe takes more time and equipment to reach, one national guide says. Another puts digging alone at $50 to $200 per foot. Soil and depth decide where a job falls in that range.
• Rock. Talbott is the most common soil around Nashville. The USDA soil survey puts its bedrock 20 to 40 inches down. Rock can show up on one lot and not the next. A Metro Codes brochure says sewer pipe may not be laid on solid rock. The rock comes out, and crushed rock goes under the pipe.
• What sits on top. Pipe under lawn costs less to reach than pipe under a driveway, one guide notes. It adds $3 to $8 per square foot to remove concrete. Another puts a slab section at $300 to $350 per foot once it is broken up and restored.
• Putting the yard back. One guide puts landscaping at $4.50 to $12 per square foot. It puts concrete driveway repair at $1 to $25 per square foot.
• Finding the problem. Most sewer projects start with a video inspection at $100 to $500, according to one guide.
• Permits. One guide puts plumbing permits at $30 to $500. Another says permits can add $100 to $1,000.

What are the signs of a failing sewer line?

One slow drain may be a simple clog. Trouble in several drains at once points to the main line, national cost guides note. Watch for these signs:

• Several drains slow or backing up at the same time
• Water rising in the tub or shower when the toilet flushes
• Gurgling drains or a sewage smell in the house
• Soggy or sunken spots in the yard over the line

Roots cause many sewer clogs, says Metro Water Services. They send feelers through tiny cracks or loose joints, then feed inside the pipe. The utility advises keeping trees and shrubs at least 10 feet from the sewer line.

Hydro jetting can clear roots and heavy clogs, one guide notes. Broken lines and large cracks still need a partial or full replacement, the same guide says.

Pipe material plays a part too. One national guide gives old clay pipe 30 to 60 years of service. It gives cast iron and PVC 50 to 100 years.

A soggy patch with no sewage smell may be a water line leak instead. Our water line repair page covers that pipe.

Who pays for the sewer line in Nashville?

The property owner does, from the house all the way to the public sewer main. Metro Water Services says there is no Metro part of the private service line. The public main may run beside or behind the lot.

Metro Water Services may still help when a plumber cannot fix a problem inside the public easement. The owner first has the line dug up and opened at the easement line, and signs a release. The utility does not bill residential customers for its repair there.

Other Middle Tennessee utilities set their own rules. Ask yours where its part of the line begins.

Does trenchless sewer repair cost less?

Per foot, usually not. One national guide puts trenchless methods at $60 to $250 per foot and digging at $50 to $200. Another lists pipe lining at $90 to $250 per foot and pipe bursting at $60 to $200.

Trenchless work can save on putting the yard back, the first guide adds. It does not suit every pipe. Another guide says it is not a fit for a collapsed pipe or one with the wrong slope.

Our sewer line work is excavation and replacement. We dig down to the bad pipe and replace it.

Do you need a permit or a locate before digging?

Tennessee law calls for a locate ticket through Tennessee 811 (dial 811) at least three working days before digging. Utilities mark their own lines only. Tennessee 811 says they may not mark private lines, so a private sewer line goes unmarked.

Permit rules vary by town, one national guide notes. In Nashville, a Metro Codes brochure on sewer service work says the inspection must be approved in writing before backfill. Hendersonville’s plumbing permit form lists sewer work as a permit item. Elsewhere, the city or county codes office answers the permit question.

How do you get a real number for your sewer line?

Cost guides show the market, and your line sets your number. Length, depth, rock and what sits on top all count. We look at the job and put the quote in writing.
