Moline is a company town built on the river: the mill city of the Quad Cities, home of John Deere World Headquarters, with the Mississippi along the north and the Rock River hugging the south and west before the two join just west of downtown. The Rock River has its own record book — 16.53 feet at Moline on April 21, 2013, the highest ever recorded. But Moline's water story doesn't need a record crest. During heavy rain, inflow and infiltration into the city's sanitary sewers push sewage back into homes — an Illinois Pollution Control Board filing says plainly that "during heavy rain events numerous homeowners have sewage backing up into their houses." It's why the city runs a Backwater Valve Program reimbursing homeowners for installing backup valves. River or sewer, Rapid Water Damage Restoration Illinois answers 24/7 in Moline.

Our Moline water damage services
Sewage cleanup
Our most-requested Moline service: category-3 extraction in full PPE after sanitary-system surcharge, removal of contaminated porous materials, and professional disinfection.
Water extraction
Mississippi overbank, Rock River rise, Sylvan Slough backflow, flash flooding, or a burst pipe in a 1910s Old Towne frame home — high-capacity pump-out for river events and interior failures.
Structural drying
Monitored dehumidification tuned to Moline's stock: brick bungalows, Victorian-era homes, mid-century ranches in Prospect Park and Park Hill — metered daily until every material tests dry.
Mold remediation
IICRC-standard containment, removal, and treatment where river-flood or sewer moisture has lingered in basements, wall cavities, and crawl spaces.
Storm damage repair
Wind-driven rain intrusion — the June 29, 2023 derecho, the April 4, 2023 EF1 tornado on John Deere Avenue — opened roofs and stripped siding: secured, extracted, dried, and rebuilt to pre-loss condition.
Common causes of water damage in Moline
- The Mississippi at record levels. All-time crest 22.70 ft (May 2, 2019); before that, 22.63 ft on July 9, 1993 — 7.63 feet above flood stage. The city's flood-hazard guidance names the Mississippi, the Rock River, and their tributaries as Moline's primary flood sources.- The Rock River. Record crest 16.53 ft on April 21, 2013; 16.38 ft on March 6, 2008; 16.21 ft on June 2, 2019. Low-lying areas along the Rock and Mississippi riverfront floodplain are the city's mapped hazard zones.
- Sanitary sewer backup during heavy rain. Chronic inflow-and-infiltration problems mean the sanitary system surcharges and sewage backs into basements — documented in an Illinois Pollution Control Board filing describing health problems and property damage. The Backwater Valve Program exists because this recurs.
- Flash flooding and derechos. The June 30, 2014 derecho caused significant flash flooding in the Quad Cities, with an East Moline neighborhood asked to evacuate late at night. The June 29, 2023 derecho brought destructive straight-line winds region-wide (88 mph measured gust at Good Hope, IL).
- The −33°F polar vortex. On January 31, 2019, Moline hit an all-time record low of −33°F — breaking −28°F from February 3, 1996 — with wind chills in the −50s to −60s. January 2019 was also Moline's snowiest January on record at 30.2 inches. Arctic outbreaks are a genuine burst-pipe season here.
- An older housing stock. Early-to-mid-1900s brick bungalows, two-story frame homes, and Victorians in river-adjacent Old Towne, Floreciente, Uptown Moline, and Willard-Wharton meet mid-century ranches in Prospect Park and Park Hill — older roofs, older laterals, older basements.

Our Moline restoration process
- Your call reaches a person, day or night. Call (773) 200-3228; we confirm what's happening — backup, floodwater, or a clean-line failure — and dispatch the right rig.
- We classify the water. Sanitary-sewer surcharge, Mississippi or Rock River overbank, storm runoff, or supply-line water: the category sets the gear, the protocol, and your insurance path.
- Extract with containment. Category-3 water is contained and extracted under full PPE; clean water gets high-capacity pump-out; unaffected areas are protected from cross-contamination.
- Moisture-mapped drying. Dehumidifiers and air movers run against mapped targets with daily meter readings — in Moline's older brick and frame homes, patience beats speed.
- Sanitize, rebuild, and prove it. Flood- and sewage-contacted surfaces are disinfected, compromised materials replaced, mold remediated to IICRC standards, and every photo and log packaged for your adjuster.
Frequently asked questions
What was the record Mississippi crest at Moline?
22.70 feet at Rock Island Lock & Dam 15 on May 2, 2019 — the all-time record, breaking the Great Flood of 1993's 22.63 feet. The river stood at major flood stage for 41-plus days.
What is Moline's Backwater Valve Program?
It's the city's own acknowledgment that basement sewer backup recurs: a program reimbursing homeowners for installing sewer or drainage backwater valves. The city's flood-hazard guidance also advises homeowners to "install a floor drain plug, standpipe, overhead sewer, or sewer backup valve to prevent backup flooding." If your block has backed up before, a valve — plus our number — is the right plan.
How cold did it get in Moline during the 2019 polar vortex?
−33°F on January 31, 2019 — an all-time record, breaking −28°F from February 3, 1996. Wind chills ran −50s to −60s, and January 2019 delivered Moline's snowiest January ever at 30.2 inches. That cold-thaw cycle is exactly when supply lines fail; unheated crawl spaces and exterior walls go first.
What was the "John Deere Avenue" tornado?
On April 4, 2023, an EF1 tornado tracked 0.88 miles through Moline along John Deere Avenue with 100 mph peak winds, damaging trees and roofs. The same morning, an EF1 struck Rock Island with widespread 90-mph straight-line winds. Tornadoes open roofs and strip siding — then rain does the real damage inside.
Do both rivers really threaten Moline?
Yes. The Mississippi borders the north, the Rock River runs along the south and west before joining the Mississippi just west of downtown, and Sylvan Slough threads between Sylvan Island and the river. Riverfront floodplain along the Mississippi and low ground along the Rock are the mapped hazard zones.
Cost factors & insurance claim help in Moline
No flat quotes — every Moline loss is scoped on its facts: the water category (sanitary sewage requires the most extensive sanitation protocol), the area that stayed wet and for how long, and how much porous material must be removed versus dried in place. Know the coverage map: sewer backups are typically covered only with a sewer/sump backup endorsement on your homeowners policy, while Mississippi or Rock River overbank flooding is a flood-insurance matter. Given the city's documented history of rain-driven backups, the backup endorsement is the single most important line on a Moline policy. We photograph and log everything, review your coverage with you, and work directly with your insurer from first call to final walkthrough.
