On April 18, 2013, it took a single day to overwhelm Downers Grove: 6.7 inches of rain fell in 24 hours onto ground already saturated by ten days of rain, and Lacey, Prentiss, and St. Joseph creeks — the village's three watersheds — all overflowed at once. The storm system failed, roughly 150 localized poor drainage areas surfaced, and homes, backyards, and streets flooded across the village; DuPage County was declared a disaster area. It was one of four flood-inducing heavy rains the village had endured in the prior decade — and it was not the last. In May 2020, 5.6 more inches fell (3.2 inches on a single Sunday), capping the wettest May on record after about three years that had delivered roughly 30 inches more rainfall than average. And beneath the downtown business district runs an 11-foot-diameter, 2,200-foot-long storm sewer still being rehabilitated. Downers Grove's homes span early-1900s Sears Catalog houses, 1960s–70s split-levels and ranches, and new construction alike (median year built 1974). When water finds your home here, Rapid Water Damage Restoration Illinois answers 24/7. Call (773) 200-3228.
Our Downers Grove water damage services
Water extraction
Creek overbank from Lacey, St. Joseph, or Prentiss creeks, storm-drain surcharge, sewer backup, or a burst pipe — high-capacity pump-out with containment for contaminated water.
Structural drying
Monitored dehumidification calibrated for everything from early-1900s Sears Catalog homes to 1960s–70s split-levels — verified with moisture meters, never by touch.
Mold remediation
Damp basements and wall cavities grow mold fast after creek floods and backups. We contain, remove, and treat to IICRC standards.
Sewage cleanup
When saturated systems back up into living space, we extract category-3 water in full PPE, remove contaminated porous materials, and disinfect every surface.
Storm damage repair
Wind-torn roofing, siding, and windows are secured, the intrusion extracted and dried, and the structure rebuilt to pre-loss condition.
Our Downers Grove restoration process
- Emergency call, any hour. Dial (773) 200-3228 day or night. Active flooding, sewage backups, and storm-damaged roofs go to the front of the line.
- Trace the water's source. Creek overbank, storm-drain surcharge, a backup, or a burst line — the source sets the protocol and frames your insurance claim.
- Extract, dry, and sanitize. Standing water comes out fast; dehumidifiers and air movers run against moisture-mapped targets; contaminated surfaces are disinfected.
- Repair and document for your insurer. Finishes are restored to pre-loss condition with a full photo and moisture-log file ready for your adjuster.
Common causes of water damage in Downers Grove
- The three-creek system. Lacey Creek drains the north, St. Joseph Creek the center, Prentiss Creek the south — all East Branch DuPage River tributaries, each with FEMA floodplain and floodway. In April 2013, all three overflowed on saturated ground.
- Extreme rainfall. April 18, 2013: 6.7 inches in 24 hours after ten days of rain. May 14–17, 2020: 5.6 inches, including about 1.5 inches in 90 minutes on May 17 — the wettest May on record. About 150 localized poor drainage areas amplify every big rain.
- An 11-foot storm sewer under downtown. The ~2,200-foot, 11-foot-diameter storm sewer beneath the downtown business district is undergoing an $8.5 million design-build rehabilitation — work that made headlines in July 2026 when a flash flood trapped two contractor workers inside the pipe.
- Flood-prone subdivisions. Residents along Whitefawn Trail (off 56th Street) reported creek overflow and sewer backup entering homes in both 1996 and 2013, including a 2013 breach in the berm between detention basins. Burlington Highlands has drawn its own stormwater improvement attention.
- Legacy drainage constraints. The BNSF corridor (extended through the village in the early 1860s) historically blocked overland drainage to St. Joseph Creek; the village has pursued a minimum uniform drainage level under its Stormwater Master Plan ever since.
- Deep-freeze pipe bursts. On February 14, 2021, the village issued bitter-cold advisories for wind chills of 15 to 25 below — the classic frozen- and burst-pipe setup for older homes.
Cost factors & insurance claim help in Downers Grove
No flat quotes — your loss is scoped on its facts: the water category (creek floodwater, stormwater, sewage, or supply water), how much of the structure was affected and for how long, and the home's age and materials. Creek flooding is generally a flood-insurance matter; burst pipes, wind-driven rain, and sewer backups (with the backup endorsement) typically fall under homeowners coverage. We document everything and work directly with your insurance company from first call to final walkthrough.
Frequently asked questions
What happened in the Curtiss Street storm sewer in July 2026?
On July 27, 2026, a flash flood trapped two contractor workers inside the village storm sewer during a rehabilitation project at the 800 block of Curtiss Street, where an ~2,200-foot, 11-foot-diameter pipe beneath downtown was being lined under an $8.5 million design-build contract. One worker was rescued July 27; the other was found dead July 28 after being carried toward St. Joseph Creek.
Which of the three creeks drains my neighborhood?
Lacey Creek covers the north, St. Joseph Creek the center, and Prentiss Creek the south — all flowing to the East Branch DuPage River. Each watershed has its own FEMA floodplain and floodway, so a flood-risk check starts with which creek is yours.
What are the village's "localized poor drainage areas"?
Roughly 150 are documented in village stormwater planning — pockets where drainage underperforms in big rains. A 2014 analysis targeted a minimum uniform drainage level village-wide (2-year/6-hour and 10-year/6-hour design storms), and DuPage County ARPA grants funded the Otis–Grant–Florence Avenue and Wisconsin Avenue drainage improvements.
I live near Whitefawn Trail — is my street still at risk?
Village stormwater-committee minutes record creek overflow and sewer backup entering homes along Whitefawn Trail (off 56th Street) in 1996 and 2013 — including a 2013 breach in the berm between detention basins. If your home is near a creek, basin, or berm, ask us about backup prevention during your inspection.
What should I do during a bitter-cold snap to prevent frozen pipes?
The village's February 2021 guidance still applies: let faucets trickle, open cabinet doors under sinks, keep vulnerable pipes insulated — and know where your main water valve is so you can shut it off fast if a pipe bursts.
