Water, fire and mold restoration in Darien, IL

ServiceMaster Restoration Services handles water and sewage cleanup, fire and smoke restoration, mold remediation, biohazard cleanup and cleaning for Darien homes and businesses, 24/7. The most useful local fact: after the July 4, 2026 storms, the City of Darien estimated about 35 homes had sanitary sewer backups, and a reimbursement program for overhead sewers followed.

Why do Darien basements get sewage backups?

In a heavy storm, groundwater can seep into sanitary sewers through cracked or root-damaged laterals, and storm water reaches them through improper connections. When a main receives more than it can carry, the Insurance Information Institute explains, sewage can push back out through basement floor drains and other low-lying openings. A City of Darien committee memo from August 2026 notes that DuPage County owns and maintains the sanitary sewer system for most of the city, and that roughly 35 homes backed up during the July 4 storms.

Ownership gets confusing. According to the city's sewer information page, Darien Municipal Services maintains the storm sewers, while three different agencies serve the sanitary side: DuPage County, the Downers Grove Sanitary District and a Hinsdale-based district. The pipe from the curb to your house is the homeowner's responsibility, so the city suggests calling first to see whether a blockage starts in public sewers.

The overhead sewer reimbursement program

An overhead sewer replaces a home's gravity sewer connection with an overhead configuration, which helps protect the house from future sanitary backups. Under the expanded program announced in August 2026, DuPage County reimburses the first $2,000 of a homeowner's paid installation cost, then 50% of the remaining eligible cost up to a county maximum of $7,500. The city adds up to $5,000 more, for a combined maximum of $12,500. The program does not cover restoration or remodeling, and residents are asked to contact the county before starting work.

First hour after a sewage backup or fire

1. Keep children and pets out of the area. Backup water is contaminated and should not be touched without gloves and boots.
2. Stop sending water down the drains. Hold off on laundry, showers and flushing until the line is clear, so you are not adding to the backup.
3. Turn off power to the basement only if you can do it from a dry floor. If not, leave it to the utility or an electrician.
4. Report it. Call the city or your sanitary district to find out whether the problem is in the public main or your lateral.
5. Photograph the water depth, the drain and damaged contents. Then notify your insurer and ask whether you carry backup coverage.
6. After a fire, wait for clearance. Ready.gov advises confirming with the fire department that the home is safe and not reconnecting utilities yourself.

Sewage is cleaned differently from clean water

Drywall, carpet and pad soaked by sewage are usually removed rather than dried in place, and hard surfaces are cleaned and disinfected. Our guide to sewage backup cleanup and Category 3 water explains why.

Is a sewer backup covered by insurance?

Usually not by a standard policy. The Insurance Information Institute says sewer backups are not covered under a typical homeowners policy or by flood insurance, and that the coverage is bought separately or as an endorsement, usually at a modest cost. Endorsement limits vary widely, so check yours before storm season rather than after.

What Darien's housing age means for repairs

Darien has 8,950 housing units, with a median year built of 1978 in the American Community Survey. More homes went up in the 1970s than in any other decade.

In all, 55.0% of the housing stock predates 1980. Homes from the 1960s and 1970s are now old enough that original clay or cast-iron sewer laterals, where they remain, may have cracked joints or root intrusion, both of which can contribute to backups. Darien also has a large share of attached and multi-unit housing: 5,420 of its units are single-family detached, and 1,854 are renter-occupied.

Pre-1978 homes bring two more checks. EPA's RRP rule requires lead-safe certified practices when paid work disturbs paint in those homes, and EPA lists vinyl floor tile and its adhesives among materials that may contain asbestos. Basement floors are often where backup water sits longest, so old tile is tested before it is pulled.

1970s split-levels and raised ranches

Split-level and raised-ranch designs common in that era often put a family room, laundry and a bathroom on the lowest level, close to the floor drain. That is convenient day to day and costly when a main surcharges, which is one reason overhead sewers and backwater valves draw interest here.

Creeks and storms around Darien

Much of Darien drains to Sawmill Creek, a Des Plaines River tributary. The Village of Willowbrook's summary of the county watershed plan says about 41.7% of the Sawmill Creek watershed lies within Darien, and DuPage County has an updated Sawmill Creek watershed plan in progress, along with plans covering Wards Creek and Prentiss Creek. The National Weather Service notes that heavy thunderstorm rain can cause flash flooding, and storms like those on July 4 are when backups tend to happen.
