How do I know if tree roots are in my sewer line?

Common signs include slow drains, gurgling toilets, frequent backups, and yard spots that stay wet. A professional camera inspection is the best way to see if roots have invaded your line.

Can I use store drain cleaners to clear tree roots?

Chemical drain cleaners aren't effective against roots and can damage older pipes. Professional root cutting or hydro jetting is safer and much more effective for removing intrusions.

Will clearing the roots once fix the problem for good?

Root removal fixes the immediate clog, but the roots often return unless the pipe is repaired or replaced. Regular inspections and possible pipe upgrades help prevent repeat blockages.

Are newer PVC pipes safer from root damage?

PVC and HDPE pipes are more resistant to root intrusion since they have fewer joints and better seals than older clay or cast iron. Upgrading to these materials can reduce future problems.

Tree Roots in Sewer Lines Mokena

Seasonal PrepUpdated July 2, 2026

Tree root intrusion is one of the most persistent causes of sewer line problems in established communities like Mokena. Whether your home sits near Main Park, along U.S. Route 45, or in a newer subdivision built in the 1990s, your sewer line may be at risk. Roots seek out moisture, and older clay or cast iron lines offer plenty of joints and tiny cracks for them to sneak in. A slow-draining toilet or gurgling basement drain can be the first warning sign. Ignore it too long and you might face a total blockage, messy backups, or even worse, damaged pipe buried under your yard.

Why Tree Roots Target Sewer Lines in Mokena

Homes across the south suburbs see this problem because our trees thrive in the humid continental climate, especially during warm, rainy summers. The clay soils and moderate water table in Mokena keep the ground moist, which helps trees grow but also encourages roots to travel far in search of water. Sewer lines buried under front lawns or near older trees are prime targets. In neighborhoods with homes built from the 1980s through the early 2000s, it's common to find original sewer piping made of clay tile or cast iron. Both materials are vulnerable to cracks over time, making it even easier for roots to get in and start spreading.

Common Warning Signs of Root Intrusion

Root problems build slowly, so spotting changes in your plumbing can save you from a bigger headache later. Watch for these signs around your home:

Slow-draining sinks, bathtubs, or basement floor drains
Gurgling sounds in toilets or floor drains, especially after heavy rain
Frequent sewer backups, even after using drain cleaners
Unpleasant odors coming from basement or yard drains
Soggy patches or greener grass near your sewer line path

Any of these can point to a partial or growing blockage underground. Roots do not only cause clogs, they also break or dislodge pipes, making a small problem much bigger if ignored.

What Our Plumbers Do to Solve Root Problems

When our crew responds to a suspected root-related sewer issue, we take a step-by-step approach. First, we inspect the line using a specialized sewer camera to spot the exact location and extent of the root intrusion. This visual lets us find cracks, offsets, and dense root balls without guessing. For clogs, we often use heavy-duty augers or hydro jetting to remove roots and clear blockages. Jetting works by blasting water at high pressure, which cuts through roots and flushes debris out of the line. In older Mokena homes, sections of the pipe may already be weakened. If roots have collapsed or shifted the line, we may recommend partial or full replacement with modern PVC piping.

Seasonal Factors That Make Root Intrusion Worse

The cycle of freeze and thaw in Mokena's winters can widen existing cracks in sewer pipes. As the weather warms in spring, roots become more active, hunting down water sources. Thunderstorms and heavy summer rains add extra water to the soil, accelerating root growth. That's why we see more root calls in late spring and early summer. Homeowners who have sump pumps often notice both their basement drainage and main sewer lines acting up during wet months. If you rely on a sump system, regular sump pump maintenance can help protect your basement, but it won't prevent tree roots from invading your sewer line itself.

How to Prevent Future Sewer Line Damage

There's no permanent fix once roots find their way in, but there are smart ways to protect your home:

Schedule an annual sewer camera inspection, especially for older clay or cast iron lines
Use root barriers or safe root-killing treatments if you have mature trees near the line
Avoid planting new trees or landscaping too close to the sewer path
Repair or replace damaged sections with PVC or HDPE pipe less prone to root damage
Have your main line cleaned with professional drain cleaning equipment to remove small roots before they become a clog

If you suspect a bigger problem or have repeated blockages, it may be time to look into pipe repair and repiping options. Our team also specializes in finding hidden leaks or damaged joints with leak detection and repair tools, so you won't be left guessing about what's happening underground.
