In Malta, a lot of homes have sewer lines made from clay tile, which is especially common in mid-century construction. Clay tile works well when new, but as it ages, it's vulnerable to tree root intrusion. This isn't a rare issue, our team sees it regularly in DeKalb County and throughout northern Illinois. Even a few small roots finding a crack or joint can lead to backups, standing water, and expensive repairs if left unchecked. Understanding why this happens and how to catch it early can make a huge difference for your home and your wallet.
Why Older Malta Homes Clog
Malta's housing stock is full of single-family homes built before PVC sewer pipe became standard. These older systems often rely on clay tile, which develops gaps or cracks over decades. With Malta's flat terrain and clay-heavy soil, tree and shrub roots are naturally drawn toward any source of moisture, even a tiny drip from a loose joint in your sewer line. Once inside, roots can quickly multiply and block wastewater flow.
We see the issue pop up most often in yards with mature maples, elms, or willows. Roots from these trees can travel 10 to 30 feet searching for water. Because Malta sits near the Kishwaukee River and sees about 36 inches of annual rainfall, our ground stays damp enough for aggressive root growth every spring and summer. This is a slow process, but over a few years, it can create serious problems underground.
Warning Signs to Watch
Tree root blockages aren't always obvious at first. Homeowners often miss the early signs until drains stop working completely. Here are some symptoms to keep an eye on:
- Frequent gurgling sounds or slow drains in bathtubs, showers, or basement utility tubs
- Toilets that back up or need plunging more than usual
- Water pooling around basement floor drains, especially after rainstorms
- Patches of greener grass along the sewer line path in your yard
- Sewer odors coming from floor drains or outdoor vents
If you notice these problems, you're probably dealing with a partial or full blockage. Don't ignore them, roots won't go away on their own, and clearing them before they completely fill the pipe makes repair far simpler and less costly. For persistent drain clogs, our drain cleaning crew uses specialized cable machines or hydro jetting to cut and flush out root masses before they become a recurring issue.
How Roots Get In
The joints between clay tile sections loosen over decades as the ground shifts through freeze-thaw cycles, which are common every winter in Malta. That's the major entry point for roots. Once roots reach inside, they start to grow, sometimes forming thick mats that trap toilet paper, wipes, and other debris. Even when the pipes don't leak much liquid, the humid air inside draws roots to the joints.
Some newer homes in the village do have cast iron or plastic sewer lines, which are less susceptible to root damage. Still, any older clay or even cast iron line near a thirsty tree is at risk. Our sewer line services include camera inspections, so we can confirm exactly where roots are entering and how extensive the problem is before breaking ground.
Steps to Keep Roots Out of Your Sewer
- Schedule a camera inspection every 2-4 years, especially if your home has original clay tile lines
- Keep large shade trees at least 20 feet from the sewer route, or avoid planting new ones over existing pipes
- Clear minor root intrusions with a mechanical auger when first detected
- Use root-killing chemical treatments as recommended by a licensed plumber, never just dump store-bought chemicals on your own
- Consider a full-line replacement with PVC if your pipe clogs multiple times per year
- Check that your yard's drainage directs water away from the sewer, so roots don't have extra incentive to seek it out
We always recommend a full visual inspection before deciding on any solution. Sometimes, targeted pipe repairs at a bad joint are enough. In other cases, the only long-term fix is a complete replacement. Our pipe repair and repiping team can walk you through the options, so you can weigh the cost versus the risk of future backups.
What Happens During Sewer Line Repairs
If roots have collapsed or crushed a section of your sewer, we'll pinpoint the location using video inspection gear. Most older Malta homes have clay lines 4 to 6 inches in diameter, running from the house out to the municipal main under the street or alley. Depending on the problem's size and location, we may need to dig a trench to remove damaged sections, or use trenchless methods for less disruption. If there's a risk of groundwater entering your basement, our crew also checks the sump pit, pump, and sump pump system for signs of stress.
Every pipe repair follows local codes and is built to last decades, using PVC or other approved materials that roots can't pierce. We can also add backflow check valves or recommend yard grading changes if recurring backups are linked to drainage issues from Malta's flat terrain and clay-heavy soil.

Because regular freeze-thaw cycles, tree growth, and soil shifts are all part of life in our region, consistent sewer maintenance saves money. We help a lot of homeowners with proactive leak detection and repair work before a minor leak becomes a big excavation job.
