At an August 2026 village board meeting, a La Grange resident laid out the numbers nobody wanted to hear: the McCook Reservoir — MWRD's Deep Tunnel flood-control facility — had filled six times in the first six months of 2026, compared with five times total in the prior five years. The intersection of Sunset and Elm floods "every single rain." And the village had seen flooding in January — "a month typically considered safe." La Grange's water problem isn't a single bad storm; it's a system running out of headroom.
The village's own records tell the same story. On June 26, 2021, a severe storm overwhelmed the sewer system, flooding basements and low-lying depressional areas. A flash flood warning on May 17, 2020, exceeded sewer capacity and flooded streets, basements, and low areas. A high-intensity, short-duration storm on June 24, 2014, did the same. Voters approved a 2015 referendum to fund flood mitigation, including the 50th Street Relief Storm Sewer from East Avenue to Spring Avenue — but the project was delayed for years by litigation with the Lehigh Hanson quarry in McCook, which had demolished part of a roughly 100-year-old sewer line in 1992 without permission.
La Grange's homes — Victorians and Tudors mixed with Colonials, American Foursquares, Dutch Colonials, mid-century moderns, ranches, and brick bungalows on tree-lined streets, median price around $550,000 — deserve defenses matched to the risk.

How We Restore Water-Damaged Homes in La Grange
- Immediate response, any hour. Call (773) 200-3228. We dispatch with extraction equipment and identify the source first — sewer surcharge, overland flow, sump failure, or burst pipe.
- Safe water removal. Standing water is extracted; sewage and floodwater get containment and protective protocols before anything else moves.
- Hidden-moisture mapping. We trace moisture with meters and thermal imaging — behind plaster, under hardwood, inside finished basement walls — because older La Grange homes hide water where you can't see it.
- Monitored drying. Air movers and dehumidifiers run until moisture meters confirm every material is dry. We verify daily and reposition as needed.
- Restore and document. Damaged finishes are repaired to pre-loss condition, areas cleaned and disinfected, and everything is photographed and logged for your insurance file.
Common Causes of Water Damage in La Grange
- Sewer capacity exceeded by high-intensity storms. The village archives document it repeatedly — June 2021, May 2020, June 2014: short, intense downpours overwhelm the system and back sewage into basements.
- Depressional-area overland flow. Low spots collect runoff when sewers and streets can't convey it; the village's June 2021 newsletter specifically documented overland flooding in depressional areas.
- The chronic Sunset and Elm flood spot. Per 2026 resident testimony, the Sunset Avenue and Elm intersection floods "every single rain" — a known problem location, not a freak occurrence.
- Flagg Creek and the Salt Creek watershed. Flagg Creek runs along the village's eastern side, and La Grange sits in the Lower Salt Creek / Lower Des Plaines watershed — creek-adjacent and low-lying properties carry extra risk in regional events like April 2013 and September 2008.
- Winter freeze and unusual winter flooding. January 2026 brought flooding in a month "typically considered safe," while deep freezes threaten older homes' plumbing and freeze sump discharge lines solid.
Our La Grange Water Damage Services
Water extraction
Sewer surcharge, overland flooding, sump failures, burst pipes — standing water removed fast with truck-mounted and portable equipment.
Structural drying
Monitored drying calibrated for Victorian plaster, hardwood floors, and finished basements — older materials that hold moisture long after surfaces look dry.
Mold remediation
Damp plaster, drywall, and wall cavities grow mold within days. We contain, remove, and treat to IICRC standards.
Sewage cleanup
After sewer-capacity events push contaminated water through drains and fixtures: extraction, sanitization, safe disposal of contaminated porous materials.
Storm damage repair
Repairs for flood, runoff, and wind-driven damage — from 19th-century Victorians to mid-century moderns — rebuilt to pre-loss condition.
Areas We Serve in La Grange
We serve all of La Grange in ZIP 60525 — including downtown's La Grange Road corridor, the recurring flood-watch area around Sunset Avenue and Elm, the neighborhoods near the La Grange Country Club's 18-hole golf course, Sedgwick Park and Denning Park, and the blocks around both Metra BNSF stations (La Grange Road and Stone Avenue, about 40 minutes to Union Station).
Cost Factors & Insurance Claim Help
Every La Grange loss is scoped on its facts — never a flat price: water category, square footage and materials affected, how long they stayed wet, and the level of finish below grade. Many La Grange losses hinge on the sewer-backup endorsement. We inspect first, document with photos and moisture logs, and work directly with your insurance company from the first call to the final walkthrough.
Frequently Asked Questions
Why does the Sunset and Elm intersection flood "every single rain"?
Because it's a known chronic spot, not bad luck. Resident testimony at the August 2026 board meeting described Sunset and Elm flooding in essentially every rain event — the signature of a localized capacity or grading problem. If your home is near that intersection, assume the next storm tests you too.
What is the 50th Street Relief Storm Sewer, and why isn't it built yet?
It's the flagship project of the village's voter-approved 2015 flood-mitigation referendum: a relief storm sewer along 50th Street from East Avenue to Spring Avenue. It was delayed for years by litigation with the Lehigh Hanson quarry in McCook, which had demolished part of a roughly 100-year-old sewer line back in 1992 without permission. As of fall 2026, MWRD is in active discussions with the village, permits have been issued, and an intergovernmental agreement is expected. Until it flows, your basement is on its own.
Why did La Grange flood in January 2026 — I thought winter was safe?
That's exactly what the resident at the August 2026 meeting said — flooding arrived "in a month typically considered safe." Winter flooding comes from rain-on-snow events and warm spells that melt snowpack faster than frozen ground and full storm systems can absorb. The lesson: in La Grange, there's no off-season for water risk anymore.
What does it mean that the McCook Reservoir filled six times in six months?
The McCook Reservoir is MWRD's Deep Tunnel facility — the region's last line of defense against sewer surcharge. Filling six times in the first half of 2026, versus five times in the entire prior five years, means the system is absorbing extreme events far more often. For your home, it means the infrastructure protecting your basement is operating near its limits.
My home has a stone foundation and big parkway trees. How does that affect my risk?
Two ways. Stone foundations on older Victorians and Tudors are more seepage-prone than poured concrete — water finds the mortar joints. And La Grange's mature tree canopy sends roots into aging clay and cast-iron service lines, cracking them and inviting blockages that turn the next surcharge into a backup.
Does the village's sewer televising project include my street?
A $500,000 HUD community-project grant is funding televising and cleaning of storm and sanitary sewers south of 47th Street. If you're south of 47th, the village is actively working your lines. If you're north of it, your sewers aren't in that project — and a private inspection of your lateral is the way to know its condition.
