As a responsible homeowner or business owner in the greater Chicago area, maintaining your property’s plumbing system is crucial to ensure the health, safety, and comfort of your family, employees, or customers. While proper maintenance, such as regular drain cleaning, can go a long way in keeping your plumbing system in top shape, there comes a time when replacing your sewer line becomes necessary. At Chicago Sewer Experts, we specialize in residential and commercial plumbing and drain cleaning services, and we’re here to guide you in identifying the signs that it’s time for a sewer line replacement.

Sewer lines play a vital role in transporting wastewater away from your property and into the municipal sewer system. Over time, however, these pipes can experience various issues, such as corrosion, age-related wear and tear, or damage caused by tree roots. Eventually, these problems may necessitate a full sewer line replacement to prevent serious issues like flooding or sewage backups.

Although sewer line replacement can be a significant investment, it can also save you from future headaches and costly repairs. By being proactive and replacing your sewer line at the right time, you can safeguard your property from potential damage and ensure the continued smooth operation of your plumbing system.

In this blog post, we will shed light on the most common warning signs that your Chicago home or business may need a sewer line replacement. We’ll also discuss the importance of working with experienced professionals to handle this project and provide insight into how Chicago Sewer Experts can efficiently and effectively replace your sewer line, minimizing disruptions to your daily life or business operations.

As a leading provider of plumbing and drain cleaning services in the Chicago area, we understand the importance of a well-maintained and properly functioning sewer system. Read on to learn more about the top signs that it’s time for a sewer line replacement and how we can help you make the right choice for your property.

1. Frequent Drain Clogs and Sewage Backups

One of the most common signs that your sewer line may need replacement is consistent issues with drain clogs and sewage backups. While a single clogged drain can usually be resolved quickly with professional drain cleaning services, multiple recurring clogs and backups could indicate a more severe problem with your sewer line. This can result from pipe collapse, intrusion by tree roots, or other forms of damage that obstruct the flow of wastewater. If these issues persist despite regular maintenance, it’s time to consider a sewer line replacement.

2. Slow Draining Water and Foul Odors

Another warning sign that your sewer line may need replacing is the presence of slow-draining water and persistent foul smells emanating from your drains. Slow drains and unpleasant odors can signal that your sewer line has become compromised due to build-up, damage, or misalignment. In addition, these issues may be an indication of a broken or detached pipe section that’s causing wastewater to seep into the surrounding soil, possibly resulting in unhealthy living or working conditions. If you notice these signs on your property, consulting with a professional plumber to assess the situation is essential.

3. Sudden Increase in Pest Problems

An unexpected increase in pest issues, such as rats, mice, or insects, can be an indicator of sewer line problems. Damaged or cracked sewer lines can provide convenient access points for pests, allowing them to enter your home or business through the gaps. If you’re noticing an unexplained increase in pest activity, consider inspecting your sewer line for any potential damage that may be attracting these unwanted visitors.

4. Soggy or Uneven Patches in Your Yard

If you observe soggy, sunken, or uneven patches of grass in your yard, it may be a sign that your sewer line is leaking. Sewer leaks can saturate the surrounding soil, leading to noticeable changes in the appearance and health of your lawn. Furthermore, foul-smelling pools of sewage in your yard are a clear indication of a serious sewer line problem that warrants immediate attention. It’s crucial to address these issues by consulting with a professional plumbing service to assess the damage and determine if a sewer line replacement is necessary.

Choosing the Right Sewer Line Replacement Method

If you suspect that your property’s sewer line may need replacement, it’s essential to work with experienced professionals, like the team at Chicago Sewer Experts. We will first conduct a thorough examination of your sewer system, using advanced methods, such as video camera inspection technology, to pinpoint the precise issue and location. Once we have identified the problem, we can determine the best course of action for replacing the damaged sewer line.

There are two primary methods of sewer line replacement:

1. Traditional Sewer Line Replacement: This method involves excavating a trench to access and replace the damaged sewer line. While this can be more invasive, it may be necessary when dealing with extensive damage, pipe collapses, or complex installations.

2. Trenchless Sewer Line Replacement: This less-invasive approach allows our team to replace the damaged sewer line without needing to dig long trenches in your yard. Trenchless technology involves inserting a new pipe liner or breaking up the old pipe while simultaneously pulling through a replacement pipe. This method is often quicker, less disruptive, and more cost-effective than traditional methods.


Recognizing the warning signs that your Chicago home or business needs a sewer line replacement is vital to avoiding potentially costly and disruptive problems, such as flooding and sewage backups. By keeping an eye out for frequent drain clogs, slow-draining water, foul odors, increased pest activity, and soggy yard patches, you can catch these issues early on and address them promptly.
