The biggest rainstorm in northeastern Illinois history — the October 9–11, 1954 flood — put its heaviest rain right here: up to 12.5 inches fell near Westmont over 48 hours, the highest measured anywhere in the event. The metro area suffered an estimated $25 million in damage, and Westmont sat at the bullseye. Nearly three decades later, the pattern repeated in a different form: on December 2–3, 1982, just 3.16 inches of rain fell in 24 hours — but on saturated ground, with the intensity of a 10-year storm, and the DuPage Progress headline read "Floods strike Westmont, Darien." Streets were barricaded at 59th and 60th between Cass Avenue and Williams. Several homes — "especially in the Fairview area" — took water from sanitary sewer backup as stormwater infiltrated sanitary sewers until they "reached capacity and backed up in residents' homes." That day, the Downers Grove Sanitary District superintendent reported every pump on line and still couldn't keep up.
The story kept going. Rainstorms in August 1987 brought a federal disaster declaration from President Reagan covering most of DuPage County. April 18, 2013, dropped roughly six inches of rain with widespread flooding — the village's water operator ran an all-hands emergency response with backup pumps, generators, storm-drain cleaning, and retention-pond pump-down. And in March 2026, DuPage County ran its regional flood-control system for the second time in two weeks: the Liberty Park facility — in Westmont itself — reached operational levels while the Elmhurst Quarry diverted more than 10 million gallons of Salt Creek floodwater overnight. The county operates 17 facilities holding nearly 6 billion gallons, and Westmont keeps needing them.
Westmont's signature flood mechanism isn't river overbank — it's the sewer. The 1982 Fairview-area precedent, the 2016 sanitary-sewer replacements on Chicago Avenue (installed "due to reoccurring maintenance issues"), and the downtown replacements behind Burlington Avenue and Lincoln all point the same way: stormwater infiltrates aging sanitary lines, the system reaches capacity, and backups hit basements. Illinois DNR research notes that urban flooding — flooded basements from storm-sewer backups — hits hardest in older sections of town and 1950s–60s subdivisions, which describes much of Westmont. This is a brick town, built by brick manufacturers like the Excelsior Brick Company after the Great Chicago Fire, and its 1950s–60s-era ranches with original clay laterals are the exact vintage the DNR flags.

Areas We Serve in Westmont
All of ZIP 60559, DuPage County: the Fairview area (the 1982 sewer-backup hotspot), North Westmont and South Westmont, the Indian Trail townhome subdivision, the King Arthur apartments (protected by the Deer Creek retention basin), downtown Westmont along Cass Avenue/Burlington, the Ogden Avenue commercial corridor, the Ty Warner Park area, and blocks near Veterans Memorial Park and the historic Gregg House (117 S. Linden Ave., National Register 1980).
Common Causes of Water Damage in Westmont
- Sanitary-sewer backup. Westmont's signature flood mechanism: stormwater infiltrates aging sanitary sewers, they reach capacity, and backups flood basements — the 1982 Fairview-area precedent, still relevant.
- Historic-scale downpours. The 1954 record (12.5 inches near Westmont), the 1987 federal-disaster storms, and the 2013 six-inch event prove this corridor can see extreme rainfall.
- Aging clay laterals and cast-iron lines. 1950s–60s-era ranch and mid-century homes with original sewer laterals — the exact vintage Illinois DNR links to urban basement flooding.
- Deer Creek and Salt Creek runoff. The Deer Creek retention basin protects the King Arthur area, and the Liberty Park flood-control facility sits in Westmont itself — but shoulder-season storms still activate both.
- Sump and storm-drain failure. Intense storms overwhelm street drainage; the village's stormwater plan was under active revision as of late 2025, signaling recognized gaps.
- High renter share. At 43.4% renters — far higher than neighboring villages — landlord/tenant water-damage disputes and delayed maintenance are common local context.
- Freeze-related pipe bursts. The brutal 2013–14 winter produced ~5,200 frozen water-service calls in Chicago; Westmont's oldest sections (Fairview, downtown, 1950s–60s subdivisions) carry the same aging-lateral profile.
How We Restore Water-Damaged Homes in Westmont
- Call (773) 200-3228 — emergencies answered around the clock. We dispatch with extraction gear, triaging active flooding and sewage backups first.
- Determine the water's route. Sanitary-sewer surcharge, storm-drain overflow, sump failure, or burst pipe — the source decides the safety and drying protocol.
- Extract with contamination controls. Standing water comes out; sewage-contaminated water gets containment and PPE protocols per IICRC standards.
- Find hidden moisture. Meters and thermal imaging trace water behind walls, under flooring, and inside finished basements.
- Dry under monitored conditions. Air movers and dehumidifiers run on logged schedules, with daily readings until materials hit their targets.
- Restore to pre-loss condition. Repairs documented from the first photo to the final walkthrough, ready for your insurer.

Cost Factors & Insurance Claim Help
No flat quotes — every Westmont loss is scoped on its facts: water category, square footage affected, materials involved, and how long they stayed wet. Sewage-contaminated losses cost more than clean-water ones; finished basements multiply scope. Coverage often hinges on a sewer-backup endorsement, so we review your policy with you — this matters here, where sanitary backup is the signature mechanism. Detailed photo logs and moisture readings give your adjuster a ready-made file, and we coordinate with your insurance company from the first call to the final walkthrough.
Frequently Asked Questions
Why does Westmont flood from sewers instead of rivers?
Because sanitary-sewer backup — not river overbank — is Westmont's signature mechanism. Stormwater infiltrates aging sanitary lines, the system reaches capacity, and backups push into basements. That's what happened in the Fairview area in December 1982, and the village's repeated sewer replacements (Chicago Avenue in 2016, downtown alleys) show it's still the recognized problem. DuPage County's regional facilities mitigate stream flooding; they don't fix lateral-level backup.
What happened in the December 1982 flood?
3.16 inches of rain fell in 24 hours on saturated ground — a 10-year-storm intensity — and the DuPage Progress headline read "Floods strike Westmont, Darien." Streets were barricaded at 59th and 60th between Cass Avenue and Williams, and several homes, especially in the Fairview area, took water from sanitary sewer backup. The Downers Grove Sanitary District had every pump running and still couldn't keep up. The Deer Creek retention basin, co-built with the village, saved the King Arthur apartments from flooding for the first time.
What's the Liberty Park facility in Westmont?
A DuPage County regional flood-control facility located in Westmont. In March 2026, the county ran its flood-control system for the second time in two weeks, and Liberty Park reached operational levels while the Elmhurst Quarry diverted 10+ million gallons of Salt Creek floodwater overnight. The county operates 17 such facilities with nearly 6 billion gallons of storage — and they see real use in shoulder-season storms.
I'm a renter in Westmont. Who handles water damage in my unit?
Typically the landlord owns the structure and its systems (plumbing, roof, sewers), while you own your belongings — but leases and circumstances vary, and 43.4% of Westmont households rent, so these disputes are common local context. Call us immediately to stop the damage; we document the source and scope, which protects both you and your landlord, and we can work with either party's insurer.
Why does the village's brick heritage matter for water damage?
Westmont grew as a brick-manufacturing town after the Great Chicago Fire — the Excelsior Brick Company, the 1872 Gregg House built to showcase its brick — and many older homes are brick or brick-veneer. Masonry walls handle drying differently than framed walls: they hold moisture longer and need controlled drying to avoid efflorescence and mortar damage. We calibrate our approach to the material.
