How professional sewage cleanup works
A documented, safety first process from the first call to a dry, disinfected space.
Emergency Dispatch
A real person answers 24/7. We gather the details and roll out fast, usually on-site within the hour.
Containment & Safety
We set isolation barriers, apply negative air when needed, and wear full PPE to stop cross contamination.
Source Control
We coordinate with your plumber to stop the backup at its source so the area does not re-contaminate.
Extraction & Removal
We pump and vacuum the contaminated water, then remove unsalvageable porous materials for regulated disposal.
Disinfection
We apply EPA registered antimicrobial cleaners to every affected hard surface with the correct dwell time.
Drying & Verification
Air movers and dehumidifiers run until daily moisture readings confirm the structure is fully dry.
Health risks of a sewage backup
Sewage is a serious health hazard. Here is exactly why it needs fast, professional cleanup.
Bacteria & Viruses
E. coli, Salmonella, Hepatitis A, and rotavirus live in sewage and cause serious illness.
Airborne Exposure
Drying sewage releases particles you can breathe in, which is why containment matters.
Mold Within 48 Hours
The moisture left behind grows mold in 24 to 48 hours, adding a second health hazard.
Higher Risk Groups
Children, older adults, and anyone with a weak immune system face the greatest danger.
The CDC and EPA both classify sewage as a serious contamination hazard. If sewage has entered your home, keep people and pets away from the area and call (773) 885-8528 for safe, professional removal.
How to clean up a sewage backup safely
If the backup is small and you must act before help arrives, follow these steps. For anything larger than a few square feet, call a professional.
- 1. Safety first. Do not enter until electricity to the area is off. Wear PPE: rubber gloves, boots, goggles, and an N95 mask. Open windows to ventilate. Keep children and pets away.
- 2. Stop the water and relieve pressure. Stop using every sink, shower, and toilet. If you can safely reach the outside mainline cleanout, removing the plug pushes overflow into the yard instead of the home.
- 3. Remove the water. Use a sump pump for standing water, then a wet/dry vacuum for the rest, working from the far corner toward the exit.
- 4. Discard porous items. Carpet, padding, mattresses, cardboard, and unpainted drywall cannot be disinfected and must be thrown away. Discard any food or medicine that touched the water.
- 5. Clean and disinfect. Wash hard surfaces with hot, soapy water, then sanitize with about 1 cup of bleach per gallon of water. Let it sit 10 minutes. Never mix bleach with ammonia, it creates toxic fumes.
- 6. Document and call for help. Photograph everything for insurance before cleanup. For any backup beyond a small spill, a certified crew is safer and protects your claim.
For official guidance, see the Illinois Department of Public Health flood and sewer cleanup page, or request a city sewer inspection from the City of Chicago Department of Water Management. When in doubt, call us at (773) 885-8528.
Why sewage backs up in Chicago homes
Chicago's older infrastructure makes backups more common than in newer cities. These are the causes we see most.
- Combined sewer system. Much of Chicago runs storm water and sewage in the same pipes, so heavy rain overwhelms the line and pushes waste back up through basement drains.
- Old clay lateral lines. Many Chicago homes still have decades old clay pipes that crack or collapse, letting tree roots and blockages cause backups.
- Basement heavy housing. Chicago's bungalows, two-flats, and garden units put finished space right where sewage enters first.
- Heavy summer storms. Big rain events tied to the regional sewer system are the number one trigger for the backups we clean.
Why sewage is Category 3 black water
The category of water decides how it must be handled and what can be saved.
Clean Water
From a clean supply line. Low risk, but it still needs fast drying before it degrades.
Grey Water
Slightly contaminated water from appliances. Carries bacteria and needs careful handling.
Black Water
Sewage and flood water. Highly contaminated, a true health hazard, and requires full protective cleanup.
What sewage cleanup costs in Chicago
Here is a realistic range so you know what to expect before any work begins.

How to prevent a sewage backup
A few upgrades can keep sewage out of your Chicago basement for good.
- Install a backwater valve. This one way valve blocks sewage from flowing back into your home when the city line surcharges.
- Consider an overhead sewer. Common in Chicago, it reroutes drainage so a backup cannot reach the basement floor.
- Maintain your sump and ejector pit. Test the pump before storm season and add a battery backup.
- Never pour grease down drains, and have old clay lines inspected for roots and cracks.

Sewage cleanup questions Chicago asks
Direct answers to what property owners search most.
Can a sewer backup make you sick?
Yes. Sewage is Category 3 black water and carries bacteria, viruses, and parasites such as E. coli, Salmonella, and Hepatitis A. Contact with it, or breathing airborne particles as it dries, can cause infections, stomach illness, and breathing problems. Keep everyone away from the area and call for professional cleanup.
What are the health risks of a sewage backup in a basement?
A basement sewage backup exposes you to harmful bacteria, viruses, and parasites, plus mold that grows within 24 to 48 hours in the leftover moisture. Airborne particles can affect your lungs, and contaminated surfaces spread illness. Children, older adults, and anyone immunocompromised are most at risk.
How much does sewage cleanup cost in Chicago?
Most sewage cleanups in Chicago run between $3,000 and $7,000, with small jobs starting near $2,000 and large contamination reaching $10,000 or more. The final cost depends on the volume, the area affected, and how much material must be removed. We give a clear estimate first.
How fast do you respond to a sewage emergency?
We answer the phone 24/7 and are usually on-site within the hour anywhere in Chicago. Sewage spreads and mold can start in 24 to 48 hours, so we treat every backup as an emergency. Call 773 885 8528 any time, day or night.
Can I clean up sewage myself?
A small spill on a hard surface under a few square feet can be handled with gloves, a mask, and disinfectant. Anything larger, anything touching drywall, carpet, or contents, or any basement backup should be left to professionals. Sewage carries pathogens and hidden moisture that cause mold and damage.
Does insurance cover sewage backup?
Often yes, but only if you have a sewer or water backup endorsement on your policy. Standard homeowner policies usually exclude backups without it. We document the damage, photograph everything, and work directly with your adjuster so your claim goes smoothly.
How long does sewage cleanup take?
Most residential sewage cleanups take 1 to 3 days. Extraction and disinfection usually finish on day one, while structural drying runs 2 to 4 days depending on how far the water spread. Daily moisture readings confirm when the area is fully dry.
What should I do right after a sewage backup?
Stay out of the affected area, keep children and pets away, and avoid using water that drains into the backed up line. Do not touch the sewage. Shut off power to the area only if you can do it safely, then call for professional cleanup right away.
Why is a sewage backup considered a health emergency?
A sewage backup is an emergency because it is Category 3 black water, loaded with bacteria, viruses, and parasites that spread illness on contact and through the air. Mold also begins within 24 to 48 hours. The longer it sits, the greater the health risk and the property damage, so fast removal matters.
Why does my basement smell like sewage after heavy rain?
In Chicago, heavy rain overwhelms the combined sewer system, pushing waste water back up through your basement floor drain. That released gas and residue is what you smell. If the smell keeps returning, it often means sewage has entered the space and needs professional cleaning and disinfection.
When should I call a professional for a sewage backup?
Call right away for any backup that covers more than a few square feet, touches drywall, carpet, or belongings, or reaches a basement. Also call if you smell sewage, see dark water, or anyone in the home is at higher health risk. When in doubt, call, sewage is not a safe do it yourself job.
Where does sewage backup water usually enter a home?
Sewage most often enters through the lowest drain in the house, which is usually a basement floor drain, a laundry drain, or a downstairs toilet. In Chicago's basement heavy homes, that means finished lower levels are hit first, which is why fast response protects the most valuable space.
Who is responsible for a sewer backup, the city or the homeowner?
It depends on where the blockage is. If it is in your private lateral line, it is usually the homeowner's responsibility. If it is in the city main, the city may be responsible. Either way, the cleanup inside your home falls to you, and we document everything to support any claim.
What happens if you do not clean up sewage properly?
Improper cleanup leaves bacteria, moisture, and odor behind. Within 24 to 48 hours mold begins to grow, contaminated materials keep spreading pathogens, and the structure can suffer lasting damage. What starts as a cleanup issue can turn into a health and repair problem that costs far more.
