Signs of Root Intrusion in Lake Zurich, Buffalo Grove, Crystal Lake & Nearby Areas

Tree roots are one of the most common causes of sewer line problems throughout Northern Illinois. Many homes in areas like Lake Zurich, Buffalo Grove, Crystal Lake, Palatine, and Evanston still have older clay or cast iron sewer lines underground. Over time, tiny cracks form in these pipes, allowing tree roots to force their way inside searching for moisture. They find it and not only grow but flourish inside.

Once roots enter a sewer line, they continue growing and expanding. Eventually they catch toilet paper, grease, waste, and debris until the pipe begins backing up into the home. We have pulled out roots as thick as 1.5 inches in diameter. Watch our video on Facebook click here.

At All Affordable Plumbing Inc., we frequently find heavy root intrusion during sewer camera inspections across Chicagoland suburbs. Some sewer lines become completely packed with thick roots, causing repeated drain backups, slow drains, sewage smells, and even collapsed underground piping.

Why Tree Roots Are Such a Big Problem in Illinois

Northern Illinois neighborhoods often feature mature trees planted decades ago. While beautiful, these older root systems are extremely aggressive toward aging sewer infrastructure.

Clay sewer pipes, especially in older neighborhoods, were installed in short sections connected by joints. Over time:

  • Ground movement shifts the pipe
  • Joints separate
  • Tiny openings form
  • Moisture escapes
  • Roots naturally grow toward the water source

According to plumbing industry studies, root intrusion is one of the leading causes of residential sewer line damage in older homes across the Midwest.

Homes built before the 1980s are especially vulnerable.

Common Signs of Tree Roots in Your Sewer Line

If you notice any of these warning signs, roots may already be growing inside your sewer pipe:

  • Multiple drains backing up at once
  • Gurgling toilets or tubs
  • Slow draining sinks and showers
  • Sewage odors indoors or outside
  • Water backing up in basement floor drains
  • Frequent drain clogs that keep returning
  • Wet spots or unusually green grass in the yard

Many homeowners first notice the issue after heavy rain or when doing laundry.

How Sewer Camera Inspections Help

Modern sewer camera inspections allow plumbers to locate the exact problem underground without digging blindly through the yard.

A waterproof camera is inserted into the sewer line to inspect:

  • Root intrusion
  • Broken clay pipe
  • Cracks or offsets
  • Grease buildup
  • Collapsed sections
  • Standing water inside the line

This helps determine whether the sewer line can be cleaned, repaired, lined, or replaced.

Hydro Jetting vs Root Cutting

Many sewer root problems can initially be cleared using professional sewer cleaning equipment.

Root Cutting

Mechanical root cutting removes thick root masses from inside the pipe.

Hydro Jetting

Hydro jetting uses high-pressure water to thoroughly clean pipe walls and flush debris downstream.

Hydro jetting is especially effective because it not only cuts roots, but also removes grease, sludge, and buildup coating the inside of the sewer pipe.

However, if the pipe is severely damaged or collapsed, repair or replacement may eventually be necessary.

Older Chicagoland Homes Are More Vulnerable

Older homes in Crystal Lake, Palatine, and Barrington often have aging clay sewer pipes that are highly vulnerable to root intrusion.

Homes with large mature trees near sewer routes are particularly at risk. Nearly all municipalities planted the trees in the parkway at the same time the street was built. These municipalities like Evanston, Crystal Lake, Palatine, Barrington are all old and therefore these trees are now mature and with a large root system.

Preventing Sewer Root Problems

While roots cannot always be prevented entirely, homeowners can reduce the risk by:

  • Scheduling periodic sewer inspections
  • Avoiding flushing grease or wipes
  • Addressing slow drains early
  • Repairing damaged sewer sections promptly
  • Removing problematic trees near sewer routes when necessary

Preventative maintenance is far less expensive than emergency sewer excavation after a major backup.

Frequently Asked Questions

Can tree roots completely block a sewer line?

Yes. In severe cases, roots can fully obstruct the pipe and cause sewage backups inside the home.

Will drain cleaner remove tree roots?

Most store-bought drain cleaners will not effectively remove heavy root intrusion and may damage pipes over time.

How often should sewer lines be inspected?

Homes with older sewer systems or previous root issues should consider inspections every 1–2 years.

Can hydro jetting damage old pipes?

When performed properly by professionals, hydro jetting is generally safe. A camera inspection is usually recommended first to evaluate pipe condition.

What type of sewer pipe is most affected by roots?

Older clay sewer pipes are the most common target for root intrusion because roots easily penetrate pipe joints.
