Sewage Backup Cleanup in Chicago, IL
Category 3 water from Chicago’s combined sewer system is a health hazard, not a mop job. Containment, removal, disinfection, and verified drying.
When Chicago’s combined sewers surcharge during a major storm, what comes back through floor drains is Category 3 water — contaminated with bacteria, viruses, and whatever else was in the system. This is the most hazardous water damage scenario a homeowner faces, and it cannot be handled with a wet vac and bleach.
Our sewage backup protocol follows IICRC S500 guidance for Category 3 losses: containment of the affected area, removal of porous materials that contacted contaminated water, HEPA-filtered negative air where needed, disinfection of remaining surfaces, and drying with daily documentation.
Signs you need this service
- Dark water or solids coming up through a basement floor drain during rain
- A sewage odor from drains, especially after storms
- Multiple fixtures backing up at once — a sign the problem is in the lateral or main, not one trap
- Standing water in the basement after a heavy Lake Michigan storm system
How we handle it
Containment
The affected area is isolated with poly sheeting and negative air so contamination does not spread to clean parts of the home.
Extraction & removal
Contaminated water is extracted and porous materials — carpet, pad, drywall, insulation — are removed and disposed of properly.
Cleaning & disinfection
Hard surfaces are pressure-cleaned and treated with EPA-registered disinfectants appropriate for sewage contamination.
Drying & clearance
The structure is dried to target moisture levels and the space is ready for rebuild once readings confirm it.

Questions about sewage backup cleanup
Is it safe to stay in my home during sewage cleanup?
If the loss is contained to a basement and properly isolated, most families stay in the home during the work. Whole-floor contamination or compromised HVAC near the loss may make temporary relocation the safer call — we will tell you straight.
Does insurance cover sewer backup in Chicago?
Standard homeowner policies usually exclude sewer backup unless you added a water/sewer backup endorsement. Given Chicago’s combined sewer system, that endorsement is worth asking your agent about before the next big storm.
