Sewer Scope Inspection: Why It Matters in Chicago

The sewer lateral - the underground pipe that carries waste from your home to the municipal main - is one of the most expensive systems not covered by a standard home inspection. When it fails, repairs can run into the thousands. A sewer scope inspection is the only way to know its condition before closing.

How a Sewer Scope Works

A small waterproof camera on a flexible cable is fed through an accessible drain or cleanout into the sewer lateral. The video is recorded in real time, and our inspector identifies blockages, root intrusion, cracks, offsets, bellies (low spots that hold water), and signs of pipe collapse. You receive the video and a written summary as part of your digital report.

Why Chicago-Area Homes Are High Risk

• Many neighborhoods still have original clay laterals from the 1920s-1960s, which crack and shift as tree roots grow.
• Mature trees throughout the city and inner-ring suburbs - beautiful, but their roots are the #1 cause of sewer line failure.
• Older cast-iron transitions corrode at the joint where clay meets the home's interior drain stack.
• Freeze-thaw cycles in Chicago winters accelerate joint failure.

When You Absolutely Should Get a Sewer Scope

• Any Chicago home built before 1985
• Any home with mature trees (especially silver maple, willow, or elm) within 25 feet of the lateral
• Homes with a finished basement
• Homes where the seller mentions any history of backups
• Any inspection where you're paying for a thorough evaluation - it's the highest-ROI add-on by far

Getting a Quote for a Sewer Scope
