What Determines Sewer Replacement Cost?

If you have roots causing sewer backups, or cracks and leaks in your underground pipes, it’s time to call a trusted plumber who can assess and address your sewer replacement needs. And while sewer line replacement may sound overwhelming and invasive of your property, it’s important to understand just how important sewer line replacement is, and how much it will cost you.

Why Sewer Replacement Matters

Sewer issues can cause slow draining in your home, foundational cracks, harmful moulding, rodent and insect issues, septic waste pooling in your yard, and sewage backup in your sinks, bathtubs, and toilets. This contaminated water is unhealthy, harmful to consume or inhale, and can make the pets and people in your home very sick.

It is, therefore, critical that you address any sewer line issues before they become worse and compromise the foundation of your home or your health. And although costly to repair, the consequences of not replacing your sewer are much more severe.

The Costs of Sewer Replacement

To ensure that you are aware of what’s involved in calculating your sewer replacement bill, we’ve compiled a list of factors that determine the cost of sewer replacement:

Technology Advancements

With new technology, plumbing issues can be solved more efficiently and effectively than ever before. Using video lines that are filtered into plumbing lines, plumbers can scan the pipe for bursts and corrosion without having to dig up your entire yard. When an issue is detected on the camera, plumbers may then focus their attention on the problematic part of the pipe – potentially needing to only fix one area if the damage is contained and easily accessible.

Less invasive, this video scanning method saves plumbers a lot of guesswork, and it will save you a lot of hassle, property damage, and money – a win/win.


Sewer lines can cause problems in very inconvenient places – such as under concrete slabs, trees, your home, and parking pads. Therefore, the more inaccessible your sewer issue may be, the more your sewer replacement may cost – as plumbers may need to remove tree roots or other external materials that are causing your plumbing concerns.

The Amount & Type of Damage

The cost of sewer replacement will also be determined by the type and amount of damage you face. For example, one small leak is much easier to fix than a pipeline that has 60 years of corrosion damage throughout the entire system.

Should your pipeline be damaged beyond repair, your system may need to be removed and replaced entirely. Be sure to discuss all of your options with your plumber to fully understand the steps involved in your case.

Application & Materials Required

As plumbers continue to find new ways to address tricky plumbing issues, there may be more than one option for your replacement or repair. For example, pipes under a concrete slab no longer need to be hammered and dug out – creating a large mess of your home or property. Instead, plumbers can now replace pipes by running a new pipe through the old pipe.

And while these new methods are less invasive and help to solve accessibility issues, it’s important to know that the length of pipe, and the type of materials required to replace your pipe, add up. In other words, the more material you need, the more expensive your replacement sewer will cost.

The Plumber You Work With

The price of your sewer replacement also comes down to the quality of the plumber you are working with. Plumbing scammers will try to increase the price of each material and service you require – attempting to take advantage of you and your property. Unfortunately, it is these same plumbers who will also cut corners and not complete the repair to code or industry standards – putting you at risk for further plumbing issues.

That is why it is so important to do your research – to ensure that you choose to work with a reliable and long-standing plumbing business that has a proven track record of success.
