How Tree Roots Can Damage Sewer Lines and What Des Plaines Homeowners Should Do

Des Plaines is a mature, tree-lined community, and that is one of the things that makes it a great place to live. But those same mature trees that shade your yard and line your streets can quietly work their way into your sewer lines, causing damage that builds for years before you ever notice a problem.

Tree root intrusion is one of the most common causes of sewer line failure in older Illinois suburbs. Understanding how it happens, what to watch for, and when to act can save you from a very expensive repair.

Why Tree Roots Target Sewer Lines

Tree roots are always searching for water and nutrients. Your sewer line carries both, and even a hairline crack or a slightly loose joint in a pipe is enough to attract root growth.

Once roots find a small opening, they push through and grow inside the pipe. Over time, they expand, branch out, and can completely block or crush the line. The older the pipe, the more vulnerable it tends to be.

Pipe Materials Common in Des Plaines Homes

Many homes in Des Plaines were built in the 1950s, 60s, and 70s, which means sewer lines are often made of materials that are now past their expected lifespan.

• Clay tile pipe, which was standard in mid-century construction, is highly susceptible to root intrusion at the joints
• Cast iron pipe, which can corrode and crack over decades, creating entry points for roots
• Orangeburg pipe, a fiber-based material used post-World War II, deteriorates badly over time
• Early PVC installations that may have shifted due to soil movement and frost heave

Illinois freeze and thaw cycles make this worse. Ground movement from seasonal frost puts stress on pipe joints, creating small gaps that roots exploit year after year.

Warning Signs of Root Intrusion

Root damage rarely announces itself all at once. It tends to develop gradually, which is why so many homeowners are caught off guard when a full blockage or collapse finally occurs.

Watch for these signs that roots may already be inside your sewer line:

• Slow drains in multiple fixtures at the same time, not just one sink or toilet
• Gurgling sounds coming from drains or toilets after water is used
• Sewage odors inside the home or near the yard above the sewer line
• Toilets that back up or bubble when you run a sink or washing machine
• Wet or unusually green patches in the yard along the path from your house to the street
• Recurring clogs that keep coming back even after being cleared

Any one of these symptoms is worth investigating. Multiple symptoms together almost always point to a sewer line issue.

How Root Damage Progresses Over Time

Root intrusion does not stay small. Once roots are inside a pipe, they continue to grow with the tree. What starts as a partial restriction becomes a full blockage, and the pressure of expanding roots can eventually crack or collapse the pipe wall entirely.

A partial blockage can still pass water slowly, which is why homeowners sometimes live with slow drains for months before things get critical. By the time a full backup happens, the pipe may already need significant repair or replacement rather than a simple cleaning.

The Real Cost of Waiting

Clearing a root blockage with a mechanical auger or hydro jetting is a manageable repair when caught early. Replacing a collapsed or severely damaged sewer line is a much larger project that involves excavation, landscaping disruption, and significantly higher costs.

In Des Plaines, where lots often have mature oaks, maples, and elms with deep root systems, the risk is real for a large portion of older properties. Waiting until you have a sewage backup in your basement is not a strategy that works in your favor.

What You Should Do Next

If you are seeing any of the warning signs above, or if your home is more than 40 years old and has never had a sewer inspection, here are the right steps to take:

• Schedule a sewer camera inspection to see exactly what is happening inside the pipe
• Find out what pipe material your sewer line is made of and how old it is
• Note the location of large trees relative to your sewer line path
• Ask about root treatment options if roots are present, but the pipe is still intact
• Get a clear picture of the pipe condition before deciding between cleaning, lining, or replacement

A camera inspection takes the guesswork out of the process. You see exactly what is in the pipe, where the problem is, and how severe the damage has become.
