Why roots are the top cause of repeat backups in older South Suburban homes.
Call (888) 217-5859In Richton Park and the surrounding South Suburbs, tree roots are one of the most common causes of sewer line trouble, especially in older homes with clay pipe. If your main sewer line keeps backing up no matter how often it is cleared, roots are a likely reason. Here is how they get in, the warning signs, and how the problem is solved.
Roots are drawn to the moisture, warmth, and nutrients inside a sewer line. They find their way into small gaps at pipe joints or hairline cracks, then grow inside the pipe into a fibrous mass. That mass catches toilet paper, grease, and debris, slowly choking off the flow until the line backs up. Older clay and cast iron pipe, with its many joints, is far more vulnerable than newer materials, which is why root intrusion is so common in established neighborhoods across the South Suburbs.
Common signs include drains that gurgle, multiple slow drains throughout the house, repeated clogs in the same line, and a drain that backs up again soon after it was snaked. A sewage smell indoors or near the outdoor cleanout, or a soggy, unusually green patch in the yard over the sewer line, can also point to roots and pipe damage. Our guide on the signs of a clogged main sewer line covers these signals in more detail.
A snake can cut a channel through a root mass and temporarily restore flow, but it leaves the roots in the pipe, and they grow back. That is the pattern behind a drain that clogs every few months. To actually clear the line, the roots need to be cut and flushed out along the whole pipe, which is where hydro jetting comes in. The trade-offs between the two methods are explained in our comparison of hydro jetting and snaking.
Hydro jetting cuts and flushes roots out along the full length of the line, which clears the blockage far more completely than snaking. A sewer camera inspection then confirms how much intrusion remains and, importantly, whether the joint or pipe is damaged enough to need a sewer repair. Roots often enter through a joint that has shifted or cracked, and once the pipe is compromised, cleaning is a temporary fix until the section is repaired.
There is no way to stop trees from growing toward a moisture source, but you can stay ahead of the problem. Periodic jetting on a line with known root intrusion keeps it clear, and a camera check shows whether the pipe is holding up. Good habits help too, as covered in our guide on how to prevent drain clogs.
Fast-growing, water-loving species are the usual offenders: silver maple, willow, poplar, and many older parkway trees common across the South Suburbs. The issue is rarely the tree you would suspect, since roots can travel a surprising distance toward a leaking joint. Removing a tree does not remove roots already in the line, which is why clearing and inspecting the pipe matters more than blaming any single tree.
If a camera shows that roots have cracked or offset a joint, cleaning buys time but not a permanent fix. Depending on the damage, a spot sewer repair might address a single bad section, while more extensive damage calls for replacing the affected run. Catching it early, when the signs in our main sewer line guide first appear, keeps the repair smaller.
On a line with active intrusion, roots can regrow within a year or two, sometimes faster in a wet season. That is why a one-time snaking rarely holds. A thorough hydro jetting followed by periodic maintenance and the habits in our clog prevention guide is the realistic way to stay ahead of roots until the pipe is repaired.
Foaming root-control products sold in stores can slow regrowth for a time, but they do not remove an established root mass and they will not repair a damaged joint. They are a maintenance aid at most effective, not a fix. For a line that is already backing up, mechanical clearing through hydro jetting is what restores flow, and a sewer repair tells you whether the joint also needs attention.
Mature trees and decades-old clay pipe make root intrusion a recurring story across Richton Park, Olympia Fields, and Flossmoor. If your drains keep backing up, roots are worth ruling in or out with an inspection. Call the number at the top of the page to get connected with a local plumber who can clear and diagnose the line.

Yes. Roots enter at joints and expand as they grow, which can crack, offset, or eventually collapse older clay and cast iron pipe.
Hydro jetting cuts and flushes roots out along the whole line, and a camera inspection confirms whether the joint also needs repair.
Early signs include slow drains, gurgling toilets, and repeat backups that return weeks after clearing. As roots grow, multiple drains back up at once. Because these overlap with other clogs, a camera inspection is what confirms roots are the cause.
They can. Clearing roots opens the line, but roots are drawn back to the moisture and often return to the same joint over time. Hydro jetting removes more of the root mass than a cutter alone, and repairing or lining the damaged joint is what stops them coming back.
Foaming root treatments can slow regrowth after the line is cleared, but they will not clear an established root mass on their own. They work as routine maintenance after mechanical removal or jetting, not as a substitute for clearing the line.
Options include periodic jetting and root treatments to keep the line clear, avoiding planting trees over the sewer lateral, and repairing or lining cracked joints that let roots in. A camera inspection shows where roots are entering so prevention targets the right spot.
Standard policies often exclude root damage and gradual wear, though some offer a separate service-line endorsement that may help. Coverage varies, so check your specific policy. A camera inspection documents the damage, which is useful either way.
