Sewer Line Replacement Cost Estimate

Sewer line replacement cost involves a lot of variables. These include the placement of the line on your property, type of plumbing as well as the length to be installed or covered.

In the case of a full replacement, such will be expected to cost more than partial sewer line replacement.

There are different scenarios when it comes to the replacement of sewer lines. Some sewer lines are located under slabs, while other situations will require replacing both the main sewer lines and lateral replacement from a house to the street.

There are also other sewer lines located in basements. All of these scenarios each have their unique pricing models.

Let’s take a look at the cost of having sewer lines replaced in each situation.

  • Cost of Replacing Sewer Lines Under Slab

You attract additional expense when carrying out sewer line replacement under slabs. Such situations call for trenching which adds an extra $150 to $200 per foot to your bill.

However, an alternative way can be found around this to cut down on expenses.

For instance, trenchless sewer line replacement costs may be found to apply to your situation.

  • Replacement Cost for Lateral Lines from House to Street

Under this situation, sewer line replacement will cost anywhere from $3,000 to $6,000.

This cost excludes the removal of existing pipes. The connection point for your city will also impact costs in a significant way.

If your replacement requires that you extend the line further out into the street, then expect to pay much higher than normal. You may end up paying as much as $25,000 or more.

  • Cost of Replacing Sewer Lines in Basements

Sewer lines found in basements can be more challenging to replace. This is because getting access to such drain lines may require cutting through concrete.

The least cost you’ll incur starts at $600. This cost excludes the cutting of concrete to gain access to the line.

Sewer Line Repair Costs

Sometimes, a sewer line may only need a few fixes to be functional again.

In such situations, replacement isn’t an option. Several things could go wrong, thus necessitating the need for repairs. Such include broken or cracked pipes collapsed lines, and fixing clogs.

All of these attract varying degrees of costs. The more challenging or demanding the sewer line repair, the higher your total costs. It will be necessary to consider each of the repair scenarios mentioned above;

  • Cost of Fixing Broken or Cracked Sewer Pipes

Sewer lines sometimes get broken or cracked.

When such faults aren’t so severe, repairs can keep them functional. In this case, a portion of the sewer line may be changed. This will cost you a fee starting from $1,050.

The cause for such breaks and cracks also needs investigation to help prevent future occurrences.

Some of the common causes of such problems include persistent drain clogs as well as excess sewage around your home due to tree root penetration of pipes.

  • Collapsed Sewer Line Repair Cost

Collapsed lines are among issues you may encounter with your sewer lines.

Fixing a collapsed line requires the replacement of certain parts. However, when the entire line is collapsed, a complete replacement would be necessary.

For partial collapse, fixing such a problem will cost around $50 to $150 per foot. The wider the area of collapse, the higher your repair costs. A replacement will cost much more when the entire line is collapsed.

  • Cost of Fixing Clog Issues

Homeowners often deal with clog issues. Such problems prevent the free flow of sewage through sewer lines.

Clogging issues mostly arise from the indiscriminate disposal of sanitary products. Products such as wipes accumulate and get stuck at sewer line joints.

Clog issues can be identified from slow-flowing drains, gurgling or bubbling sounds as well as foul odors. Having a plumber fix the problem will cost around $45 to $200 per hour.

Sewer Line Removal Cost

So far, we’ve been talking about replacement and repair costs for a sewer line.

In the case of trenching, the cost is charged per square foot at $4 to $12. Digging up a sewer line may also be charged per square foot or a lump sum may be required.

When paying per square foot, you’re likely to incur a cost ranging from $50 to $250.

Digging and replacing the sewer line will cost anywhere from $3,000 to $25,000. Excavation costs will increase when the situation is a bit complicated.

Cleanup and Restoration Costs

As discussed above, getting access to your sewer lines may involve tearing down or digging up certain structures.

Such actions require tidying up and fixing any alterations to the structure. Now, cleanup and restoration may incur significant costs based on the level of a teardown.

Such costs range from $500 to $10,000. The size of the area covered also impacts the cost of service.

The nature of repairs may include sidewalk or driveway repaving, landscape replacement, or replacing certain structures like fencing or sheds.

So far, we’ve seen that sewer line replacement and repair costs are quite varied. These include the cost of digging or cutting through structures to gain access to sewer lines.

At the end of the replacement or repair, the repair area will need to be cleaned up and restored. This also attracts a fee.
