Root Intrusion Sewer Repair in St. Louis

Tree and shrub roots are the number one cause of sewer line damage in older St. Louis neighborhoods. Roots seek out moisture and can penetrate small cracks in clay and concrete pipes, growing until they completely block the line. Gateway Sewer Pros specializes in root removal and long-term solutions that prevent roots from returning.

How We Remove Root Intrusion

We start with a camera inspection to see the extent of root growth. Mechanical cutting removes the roots inside the pipe. We then hydro jet the line to clear all debris. Depending on how much damage the roots caused, we may recommend pipe lining to seal cracks and prevent re-entry, or pipe bursting to replace a heavily damaged section.

Preventing Root Return

CIPP pipe lining is the best long-term solution — it creates a jointless, seamless pipe that roots cannot penetrate. Combined with root killer treatment for any trees near the line, it stops the cycle for good. Call (314) 888-5374 for a free root intrusion inspection.

We provide this service across the metro — see our Creve Coeur and Brentwood pages, or all services.

Why Snaking Never Ends the Problem

Snaking cuts roots out of the pipe. It does nothing about the opening they came through. Clay tile laterals were laid in short sections with joints that were never watertight, and roots find those joints because that is where moisture escapes. Cut them back and the same root system returns through the same joint, typically within a season or two, which is why so many homeowners here have a standing annual appointment. The permanent fix is sealing the joints, and that means lining or replacement. Chemical root treatments buy a little more time than mechanical cutting but work on the same principle — they kill what is inside the pipe without closing the door. We will keep cleaning a line for you if that is what you want, but we will also tell you plainly that it is maintenance rather than repair.

Common Questions

Do I have to remove the tree?

Usually not. Sealing the pipe removes the pathway, which is the actual problem. Roots grow toward moisture; a watertight line stops offering any. Removing a mature tree is rarely necessary and rarely the cheaper option.

How often will roots come back after cleaning?

Commonly within six to eighteen months, depending on the species and how aggressive the root mass is. If you are calling annually, the arithmetic on a permanent repair has probably already turned in its favour.

Do chemical root killers work?

They extend the interval somewhat and they are cheap. They do not seal the joint, so they postpone rather than solve. Worth using while you plan a permanent repair; not worth relying on indefinitely.
