In September 2008, floodwater took River Road. That storm pushed the West Branch DuPage River out of its banks and into commercial buildings and homes along River Road, across the Warrenville Road bridge, and into Bower Elementary School. Two years later, the DuPage County Board and Stormwater Committee approved the fix — a protection berm at Bower School, a raised River Road, the Warrenville Road bridge replacement, and corridor restoration — all born from that one storm. The West Branch still runs through Warrenville (ZIP 60555), a village about 31 miles west of the Loop settled by Julius Warren in 1833 that keeps its semi-rural feel, its forest preserves, and its Tree City award. A National Weather Service gage monitors the river right here in town: during the May 2020 storm it reached 12.8 feet against a flood stage of 11.5. Upstream sits the Fawell Dam, built 1969–1971 in the McDowell Grove Forest Preserve with three 10-by-10-foot operable slide gates and operated by DuPage County since 1998, storing floodwaters to reduce flood heights downstream. When that storage fills, Warrenville's low ground near the West Branch and River Road feels it first.

Common Causes of Water Damage in Warrenville
- West Branch DuPage River flooding. The primary riverine hazard. September 2008 is the benchmark — commercial and residential flooding along River Road, the Warrenville Road bridge, and Bower Elementary — and the May 2020 event (12.8 feet versus an 11.5-foot flood stage) showed the river still tops its banks.
- Sump-pump and basement seepage in low-lying areas. Low ground near the West Branch and River Road depends on sump systems; when river levels rise or storms stall, seepage overwhelms them.
- Post-2008 infrastructure still under stress. The 2010 watershed-plan addendum funded the Bower School berm, the raised River Road, the bridge replacement, and corridor restoration — real improvements, but engineered to a design storm, not every storm.
- 1970s–1990s housing vulnerabilities. 72% of Warrenville housing was built 1970–1999 — ranches, split-levels, and two-stories whose original sump pits, foundation drainage, and water heaters are reaching end of life. The older farmhouses and 1950s cottages carry older service lines.
- Winter freeze bursts. No Warrenville-specific freeze event is documented, but the county's hazard plan lists extreme cold and ice storms as priority hazards. Older cast-iron water mains and pre-1960 clay-tile service lines are the typical regional vulnerability — nearby Naperville saw a water-main break on Ogden Avenue in the January 2019 deep freeze.

Our Warrenville Water Damage Services
Water extraction
High-capacity pumping for West Branch floodwater and basement seepage alike, with containment protocols where river water or sewage is involved.
Structural drying
Monitored drying for ranch and split-level framing, drywall, and finished basements, verified with moisture meters — because a basement that "feels dry" after River Road seepage often isn't.
Mold remediation
River flooding that sits in basements breeds mold behind paneling and under flooring. We contain, remove, and treat to IICRC standards.
Sewage cleanup
When sanitary systems back up during major storms, we extract, sanitize, remove contaminated porous materials, and disinfect salvageable surfaces.
Storm damage repair
Repairs for flood, runoff, and wind-driven damage on ranches, split-levels, farmhouses, and condos — rebuilt to pre-loss condition.
How We Restore Water-Damaged Homes in Warrenville
- Your call, answered around the clock. Reach us at (773) 200-3228 any hour — active river flooding and sewage events move to the front of the queue.
- On-site assessment. We walk the property, identify whether the water came from the river, the sump, a line, or the sanitary system, and make the scene safe.
- Rapid extraction. Standing water comes out fast with truck-mounted and portable equipment; contaminated water is handled under containment from the start.
- Moisture mapping and tracked drying. We map hidden moisture behind walls and under floors, place air movers and dehumidifiers, and log readings until every material tests dry.
- Sanitizing and mold prevention. Affected areas are cleaned and disinfected; damaged materials are removed before mold takes hold.
- Rebuild and claim support. We restore finishes and keep the photo and moisture documentation your insurer expects, working directly with your company through the final walkthrough.
Cost Factors & Insurance Claim Help
No flat pricing — your Warrenville loss is scoped on its facts: the water category (clean supply water, river floodwater, or sewage), the square footage and materials affected, how long they stayed wet, and whether finished basements or original 1970s mechanicals complicate the work. Riverine flood losses and sewer backups often hinge on specific policy endorsements, so we review your coverage with you before work begins. We document everything and work directly with your insurance company from first call to final walkthrough.
Frequently Asked Questions
What happened in Warrenville during the September 2008 flood?
The September 2008 storm is the village's most documented flood fight: the West Branch produced commercial and residential flooding along River Road, flooding at the Warrenville Road bridge, and flooding at Bower Elementary School. It was severe enough that DuPage County's 2010 watershed-plan addendum funded the Bower School protection berm, the raising of River Road, the Warrenville Road bridge replacement, and corridor restoration.
What is the Fawell Dam, and does it protect my home?
The Fawell Dam sits on the West Branch in the McDowell Grove Forest Preserve between Naperville and Warrenville. Built 1969–1971 and operated by DuPage County since 1998, it stores floodwaters to reduce flood heights downstream, using three 10-by-10-foot operable slide gates. It helps the whole corridor — but it reduces floods, it doesn't eliminate them, which is why low areas near River Road remain exposed.
My home is a 1970s split-level near River Road. Why does my basement keep seeping?
Three things line up against you: the West Branch's high-water mark in your stretch of town, a basement that traps moisture, and mechanicals — sump pump, pit, check valve, discharge line — often original to a 1970s build and past their service life. Seepage that recurs in the same spot usually means the drainage system, not the storm, is the limiting factor.
What did the county actually build after 2008 to fix the flooding?
In 2010 the DuPage County Board and Stormwater Committee approved four projects: a protection berm at Bower School, raising River Road, replacing the Warrenville Road bridge, and corridor restoration along the West Branch. They reduced risk along the corridor — they did not make the floodplain dry land.
Does Warrenville have combined sewers that could back up into my basement?
No combined-sewer system was found for Warrenville; DuPage County municipalities operate under the county's MS4 permit program, meaning separate sanitary and storm systems. The typical basement-water story here is riverine seepage and sump-pump dependence in the low-lying areas near the West Branch and River Road — not combined-sewer surcharge.
