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
Safety comes first: shut off electricity to the area, wear PPE, and keep everyone clear until it's assessed. For the full walkthrough, PPE checklist, and the exact line between a DIY job and a call-a-pro job, see our complete sewage backup cleanup guide. For anything larger than a small, contained spill, our crew handles extraction, disinfection, and drying start to finish.
Why sewage backs up in Chicago homes
Chicago's combined sewer system, aging clay lateral lines, and basement-heavy housing stock make backups more common here than in most cities. Read the full breakdown of causes, including which neighborhoods see it most, in our Chicago sewage backup guide.
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.

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 backup like this 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 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. Contamination 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.
How long does sewage cleanup take?
Most residential cleanups like this 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 water. 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 backup like this 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 contaminated water 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 it, see dark water, or anyone in the home is at higher health risk. When in doubt, call, this is not a safe do it yourself job.
Where does sewage backup water usually enter a home?
It 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.
Who is responsible for a sewage backup, the landlord or the tenant?
It usually comes down to what caused the blockage. If a tenant put grease, wipes, or other items down the drains that they were not built for, the tenant may be liable. If the cause is tree roots, a collapsed line, or an aging main, that is typically the landlord's responsibility as the property owner. Either way, document the damage with photos and keep every message in writing, because the cause is what decides who pays.
What are my rights as a renter if my landlord will not clean up a sewage backup?
Raw sewage in a rental is a health hazard, and most areas require a landlord to keep the unit habitable. Photograph everything, put every request to your landlord in writing, and if they will not act, you can often hire an emergency plumber and ask them to note it as an emergency backup on the invoice. Rent deduction or escrow may be an option as a last resort, and if the problem may start outside your unit, call 311 so the city can check its side of the line.
Will you just clean up the sewage, or do you have to gut the whole area?
It depends on what the water touched. Sealed, hard surfaces can often be extracted, sanitized, and dried with no demolition at all. Porous materials like carpet, padding, and unsealed drywall that soaked up Category 3 water usually cannot be saved and have to come out. We scope the job to the actual contamination, explain what has to go and what can stay, and give you the estimate before any work starts, so you are never surprised by the scale.
Isn't my sump pump supposed to handle a sewage backup?
No. A sump pump is built to move clean groundwater away from your foundation, not raw waste. Running it through the pump can clog and ruin the motor, and it will not stop a backup that is pushing up through your floor drain or toilet. It needs proper extraction and disinfection, not a sump pump.
Does a backwater valve stop every sewage backup?
A backwater valve stops waste that is trying to flow back into your home from the city line, so it is very effective against municipal backups during heavy rain. It does not help if the clog is on your own lateral line, and a valve installed at only one point can shift pressure and cause a backup elsewhere in the house. It is strong protection, but it is not a cure for every cause.
Can sewage bacteria spread through my house through the furnace or HVAC?
It can, which is why containment matters. If contaminated water reaches a return vent or the system keeps running, airborne particles can circulate to other rooms. We shut down the affected HVAC, contain the area, and use HEPA air filtration to capture aerosols, not just surface disinfection. If a backup is near your furnace or ductwork, turn the system off and keep everyone out of that area until it is assessed.
What do I do with the solid waste after cleaning up sewage?
Never put it down a storm drain or flush large amounts back into the system. Solid waste and contaminated materials should be double-bagged in heavy trash bags, sealed, and set out with your regular household trash following local waste rules. For anything beyond a small amount, a professional crew removes and disposes of biohazard waste properly, which also keeps you from cross-contaminating the rest of your home.
Do plumbers clean up sewage?
Not usually. A plumber stops the backup at its source by clearing the blockage or repairing the line, but plumbers are not equipped to extract contaminated water, disinfect the structure, or dry it out. That cleanup is a separate, certified job. Most backups need both trades: a plumber for the line, and a restoration crew like us to remove the waste, sanitize, and dry the space before mold starts.
How do I get rid of the sewage smell after a backup?
The smell means contamination is still present, so it will not clear with air freshener because the source is bacteria in porous materials and trapped moisture. Proper odor removal means discarding materials that cannot be sanitized, disinfecting hard surfaces with EPA registered products, and drying the structure completely. Once the area is fully cleaned and dried, the smell goes with it.
