How Tree Roots Affect Sewer Lines in Chicago & How a Sewer Scope Helps

In Chicago, mature trees are part of what gives neighborhoods their charm. From historic bungalows to classic two-flats, tree-lined streets are everywhere. But underground, those same trees can create serious problems for sewer lines, especially in older homes. A sewer scope can help identify where the problems are.

Why Tree Roots Target Sewer Lines

Tree roots naturally grow toward moisture and nutrients. Sewer lines provide both. Many Chicago homes, particularly those built before the 1970s, still rely on clay, cast iron, or older concrete sewer pipes. Over time, these materials develop tiny cracks or loose joints. Roots sense the moisture escaping through those openings and slowly work their way inside.

Once inside, roots expand. As they grow, they can restrict wastewater flow, catch debris, and eventually cause full blockages. In colder months, trapped waste can freeze and worsen the issue. Left unaddressed, root intrusion may lead to cracked pipes, sewer backups, or costly emergency repairs.

Common Signs of Root Damage

Homeowners often don’t realize roots are the issue until problems escalate. Warning signs include:

• Slow drains throughout the home

• Frequent drain clogs

• Gurgling sounds from toilets or sinks

• Sewage odors indoors or outside

• Water backing up in floor drains

Because these symptoms can also point to other plumbing issues, visual confirmation is critical.

How a Sewer Scope Inspection Helps

A sewer scope inspection uses a high-resolution camera to visually inspect the sewer line from the inside. The camera is fed through a cleanout or drain and provides real-time footage of the pipe’s condition.

For Chicago homeowners, a sewer scope can:

• Identify tree root intrusion early

• Locate cracks, offsets, or collapsed sections

• Determine the severity of root damage

• Help avoid unnecessary digging or guesswork

This inspection is especially valuable during real estate transactions. Buyers can see exactly what’s happening underground before finalizing a purchase, potentially saving thousands in unexpected repairs.

Why Early Detection Matters

Catching root intrusion early can mean the difference between routine maintenance and a full sewer line replacement. In many cases, roots can be cleared and managed before they permanently damage the pipe.

In a city like Chicago, where aging infrastructure is common, a sewer scope inspection offers peace of mind—and a clear picture of what’s happening below the surface.
