When It’s Time to Replace Your Sewer Line in Schaumburg or Evanston
A failing sewer line isn’t just an inconvenience—it’s a health hazard and a property emergency. Homes built before the 1970s in Schaumburg and Evanston often have original clay, cast iron, or Orangeburg sewer pipes that have reached the end of their useful life. Tree root intrusion, pipe collapse, and persistent backups are signs that repair may no longer be enough.
At MMDS, we specialize in both trenchless and traditional sewer line replacement for homes across the Chicago suburbs. Below, we’ll explain both methods, compare costs, and help you understand which approach is right for your property.
Signs You May Need Sewer Line Replacement
- Recurring backups: If drain cleaning solves the problem for only a few weeks or months, the pipe itself may be compromised.
- Multiple slow drains: When several fixtures drain slowly at the same time, the issue is likely in the main sewer line, not individual drains.
- Sewage odor in your yard: A cracked or collapsed pipe can leak sewage into the surrounding soil.
- Sinkholes or wet spots: Unexplained soggy areas in your yard can indicate a broken sewer line.
- Foundation cracks: In severe cases, a leaking sewer line under or near your foundation can cause settling and cracking.
- Camera inspection reveals damage: A sewer camera shows cracks, offsets, root intrusion, or collapse that can’t be cleared mechanically.
Trenchless vs. Traditional Sewer Replacement
Traditional (Open-Trench) Replacement
The conventional method involves digging a trench along the entire length of the sewer line—from your home to the municipal connection at the street. The old pipe is removed and a new one (usually PVC or ABS) is laid in its place.
When traditional is the right choice:
- The pipe has completely collapsed and there’s no remaining structure to line
- The pipe has a significant belly (low spot) that trenchless can’t correct
- The pipe route needs to change (regrading, rerouting around obstacles)
- Access is relatively easy (no major landscaping, driveways, or structures in the way)
Trenchless Pipe Lining (CIPP — Cured-in-Place Pipe)
CIPP involves inserting a resin-coated flexible liner into the existing pipe, inflating it against the pipe walls, and curing it with heat or UV light. The result is essentially a new pipe inside the old one—with a smooth, jointless interior that resists roots and corrosion.
When trenchless lining works best:
- The existing pipe is structurally intact enough to serve as a host
- The pipe runs under driveways, landscaping, or structures you don’t want to destroy
- You want faster completion (typically 1 day vs. 3–5 days for open trench)
- Root intrusion has caused cracks but not complete collapse
Trenchless Pipe Bursting
Pipe bursting pulls a new HDPE pipe through the old one while simultaneously breaking the old pipe outward. It replaces the pipe entirely rather than lining it.
Best for: Collapsed pipes or pipes that are too deteriorated for lining, but where you still want to minimize excavation.
Sewer Line Replacement Costs in the Chicago Area
| Method | Typical Cost (50–100 ft run) | Timeline | Landscape Impact |
|---|---|---|---|
| Traditional open-trench | $5,000–$15,000 | 3–5 days | Significant (full trench) |
| Trenchless CIPP lining | $6,000–$12,000 | 1 day | Minimal (2 access pits) |
| Trenchless pipe bursting | $7,000–$15,000 | 1–2 days | Minimal (2 access pits) |
| Spot repair (5–10 ft section) | $1,500–$4,000 | 1 day | Moderate (localized dig) |
Costs vary based on pipe depth, length, soil conditions, and whether the municipal connection (tap) needs replacement. Permits and inspection fees are typically $200–$500 additional. Financing through Sunbit and PowerPay can help manage the investment.
The Sewer Camera Inspection: Your First Step
Before recommending any replacement method, we always start with a sewer camera inspection. A waterproof camera is fed through the pipe to assess:
- Pipe material and condition
- Location and severity of cracks, offsets, and collapses
- Root intrusion extent
- Belly (low spots) where water and waste pool
- Exact location and depth of the problem (using a locator transmitter)
Camera inspection costs $250–$500 and is the most important diagnostic tool for sewer problems. It prevents unnecessary digging and ensures we recommend the right solution.
Pipe Materials: What’s Going In
| Material | Lifespan | Used In |
|---|---|---|
| PVC (Schedule 40) | 75–100 years | Traditional replacement |
| HDPE (High-Density Polyethylene) | 75–100 years | Pipe bursting |
| CIPP epoxy liner | 50+ years | Trenchless lining |
| ABS | 50–75 years | Some traditional replacements |
What About Tree Roots?
Tree roots are the #1 cause of sewer line failure in Schaumburg and Evanston. Mature trees—especially silver maples, willows, and elms—send roots toward sewer lines because they’re attracted to the moisture and nutrients inside. Once roots enter through a joint or crack, they grow rapidly and can completely block the pipe.
Prevention after replacement:
- CIPP lining creates a jointless pipe that roots can’t penetrate
- PVC and HDPE have fewer joints than clay, reducing entry points
- Root barriers can be installed around the new pipe
- Annual maintenance with a root-cutting tool can prevent re-intrusion
Frequently Asked Questions
How do I know if my sewer line needs replacement or just cleaning?
A camera inspection will tell you definitively. If the pipe shows cracks, offsets, bellies, or root damage that goes beyond surface intrusion, replacement is usually more cost-effective than repeated cleanings. If the pipe is structurally sound and roots are the only issue, mechanical cleaning plus root treatment may buy you more time.
Does homeowner’s insurance cover sewer line replacement?
Standard homeowner’s insurance typically does not cover sewer line replacement due to wear and tear or root damage. However, many insurers offer add-on “service line coverage” for $5–$10/month. Check your policy or ask your agent about this endorsement—it can cover $10,000+ in repair costs.
Do I need a permit for sewer line replacement?
Yes. Both Schaumburg and Evanston require plumbing permits for sewer line work, and the work must pass inspection. MMDS handles all permitting and scheduling of inspections.
Can I stay in my home during the work?
For trenchless methods, yes—the work is usually completed in one day and water/sewer service is interrupted for only a few hours. For traditional replacement, you may need to make arrangements for 1–2 days if the interior cleanout needs relocation.
What happens to my yard after traditional replacement?
We backfill and grade the trench, but settling will occur over the following months. We recommend waiting 3–6 months before re-seeding or re-landscaping the area. Any driveway, sidewalk, or patio sections that were removed will be restored as part of the project.
