Sycamore’s historic neighborhoods are part of what makes the city special. Tree-lined streets, well-kept properties, and a downtown that still looks and feels like a genuine Illinois community. But underneath many of those charming older homes, the original sewer lines are reaching — or have already passed — their expected lifespan.
If your Sycamore home was built before 1980, there’s a strong chance your sewer lateral is clay tile. If it was built between 1980 and 2000, it may be early PVC or a combination of materials where the older original line connects to newer sections. Either way, age is the single biggest risk factor for sewer line failure in residential properties.
Why Sewer Lines Fail in Older Sycamore Homes
Clay tile joint separation. Clay sewer pipe was installed in 4-foot sections joined together with mortar or oakum. Over 50+ years, ground movement, frost heave cycles, and vibration from traffic gradually separate those joints. Once a joint opens even slightly, roots find it, soil enters the pipe, and the deterioration accelerates.
Root intrusion. Sycamore’s mature trees — the ones that give the city its name — have root systems that extend well beyond the drip line of the canopy. Sewer laterals running through front yards are prime targets. Roots don’t just clog the pipe; they physically break it apart over time, widening cracks and displacing joints.
Pipe bellying and settlement. The clay-heavy soils in DeKalb County shift with moisture and freeze-thaw cycles. Over decades, this can cause sections of pipe to sag, creating low points where waste collects. A bellied pipe can’t be cleared with drain cleaning alone — the low section needs to be repaired or replaced to restore proper flow and grade.
Orangeburg pipe (bituminous fiber). Some homes built in the 1940s through 1960s used Orangeburg pipe — a tar-impregnated cardboard material that was inexpensive and easy to install. If your Sycamore home still has Orangeburg in any section of the sewer lateral, replacement isn’t a question of if — it’s when. This material collapses and deforms under soil pressure and has a much shorter lifespan than clay or PVC.
How Sewer Line Inspection Works
The first step in any sewer repair decision is a camera inspection. A waterproof, lighted camera is fed through the sewer line from an interior cleanout. This gives your plumber a live view of the pipe’s condition — cracks, root masses, offset joints, belly sections, and any material deterioration are all visible on camera.
Good plumbers mark the location and depth of each problem area, which determines whether a targeted spot repair will solve the issue or whether a longer section (or the full lateral) needs replacement.

Repair vs. Replacement — Making the Right Call
Not every sewer line problem requires full replacement. Here’s a general framework:
Spot repair makes sense when the damage is limited to one or two joints or a single short section, the rest of the pipe is in acceptable condition on camera, and the damaged area is accessible without major landscape or hardscape disruption.
Full replacement is the better investment when the camera shows deterioration throughout the line, the pipe material is Orangeburg or severely degraded clay, root intrusion is occurring at multiple joints, or the pipe has multiple belly sections indicating widespread settlement.
Your plumber should be transparent about which option they’re recommending and why. If someone tells you the entire line needs replacement without running a camera first, get a second opinion.
What About Your Neighbors?
Sewer line age tends to be consistent within a neighborhood — homes built around the same time usually have the same pipe material and are experiencing similar degradation. If your neighbors on Somonauk Street, North California Street, or anywhere in Sycamore’s older residential areas have already dealt with sewer failures, your home may be approaching the same tipping point.
Being proactive with an inspection costs a fraction of what an emergency sewer backup costs in cleanup, repair, and property damage. The City of Sycamore Public Works Department can provide information about municipal sewer main maintenance, but the lateral from your home to the main connection is the homeowner’s responsibility.
