Common Causes of Sewer Backups in Chicago
Chicago's older sewer infrastructure and tree-lined neighborhoods create predictable backup causes. Here are the big ones.
Sewer backups in Chicago usually come from a handful of familiar causes. Knowing them helps you spot trouble early.
Tree roots are one of the most common — they find their way into older clay and cast-iron lines and gradually block the flow. Grease buildup, especially in kitchen lines, is another major culprit. Aging pipes, shifting ground, and the city's combined sewer system all contribute too.
The good news is that most of these are preventable with regular maintenance and catchable early with a camera inspection. If you're seeing warning signs, the sooner we look, the smaller the fix tends to be.
